Hospi-Gard®AirCeil™
HEPA Filtration System
■Introduction
Purpose
The Hospi-Gard®AirCeil™ module is a self-contained, ceiling-mounted HEPA ltration system specically designed to provide
a high velocity airow pattern to lter out unwanted room particles including airborne microbiological contamination. The
AirCeil can either recirculate clean air back into the room or exhaust the air out to create a cost effective, negative pressure,
patient isolation room.
Description
Air enters the module through the intake grille located on the lower section of the unit. The air is evenly drawn by the motor/
blowers rst through a prelter and then through a High Efciency Particulate Air (HEPA) lter before being recirculated back
into the room through the Ceiling Filtered Air Diffuser. Alternatively, the HEPA ltered air can be exhausted to the outside or
returned to the main HVAC system to create negative pressure. Whether used for recirculation or exhaust, the Hospi-Gard
AirCeil moves air at a variable volume ranging from 300 – 600 cubic feet per minute (ft3/min) to carry away airborne particles
generated by the patient or activities within the room.
Features
• The self-contained, ceiling mounted HEPA ltration system is designed to t in a standard 2 ft x 4 ft T-bar ceiling grid or
other ceiling types.
• Designed to effectively create a low-cost negative pressure isolation room to meet CDC and OSHA guidelines.
• Tamper resistant IR hand held remote controller allows for “hands off” controlling of the module.
• The optional Ceiling Filtered Air Diffuser and 12-inch Clear Flexible Ducting allows the unit to be converted from a 100%
exhaust system to a total air recirculation system.
• Total height of the unit does not exceed 19.5 inches.
• Pending FDA and cUL listing.
• HEPA lter and prelter are room-side replaceable.

■Operation
Airow Indicator Light
The Airow Indicator light on the AirCeil control panel (Figure 3 below) glows red when the unit is running and green when in
the standby mode or when adjusting the speed with the hand held IR Remote Controller.
Note: When the AirCeil is “OFF” both the red and green indicator lights are not lit.
AirCeil Flow-Set
The Flow-Set is a hand held Infrared Remote Controller congured to adjust the airow of the AirCeil unit. The combined use
of the Flow-Set Transmitter and the Infrared Sensor mounted on the control panel of the AirCeil, allows the motor to be turned
“ON” or “OFF”, adjustments to the airow index (from 1-100) and conrms the current airow setting.
Note: When any of the Flow-Set buttons are depressed, the Flow-Set Indicator Light will ash, indicating that a change has occurred.
During an adjustment session, the green Setting Indicator Light on the AirCeil Control Panel ashes each time a valid entry is made.
• The button to the left of the up arrow quickly increases to the airow index by increments of ten (see Figure 4).
• The button to the left of the down arrow quickly lowers to the airow index by increments of ten.

• Similarly, using the set of buttons to the right of the arrows 1 allows ne, single digit adjustments to the airow index.
• If the airow index is already set to its maximum value of 100, any further attempts to raise the airow index using either
the 10 button or the 1 button will not be allowed. The green Setting Indicator Light will not blink, indicating an invalid entry.
• With an airow index of 91, depressing the 10 button will be considered an invalid entry. The green Setting Indicator Light
will not blink and the increase will not occur because this entry would take the airow index above 100.
• The 1 and 10 buttons respond in a similar manner during any attempts to set the airow index below 1 because 0 is not
a valid airow index.
Turning the AirCeil “ON” (Run Mode)
1. Point the Flow-Set Transmitter toward the Infrared Sensor on the AirCeil control panel.
2. Press the ON/OFF button once and the both the red operation light and the green setting light will glow conrming the unit is “ON.”

Note: If the Controller’s buttons are inadvertently depressed or you enter an adjustment session but do not modify the
airow setting, the adjustment session automatically terminates after 15 minutes of inactivity.
Viewing the Current Motor Speed or Airow Setting
1. With the unit in the Run Mode, depress the Clear button once.
2. The green Airow Setting Indicator Light begins to ash indicating the signal was received.
3. The green ash sequence indicates the current airow index (1-100).
4. The green ash sequence occurs in two sets, with rst set of long ashes representing the tens digit setting and the
second set of short ashes representing the single digit setting.
5. An extra long ash replacing either the long ash(es) or the short ash(es) indicates the value of the corresponding tens
digit or single unit digit setting is zero.
• Example 1: Two long ashes followed by four short ashes represents an airow index of 24. The motor will be operating
at approximately 24% of its maximum capacity.
• Example 2: Eight long ashes followed by nine short ashes represents an airow index of 89. This setting indicates that
the motor is operating at approximately 89% of its maximum capacity.
• Example 3: An extra long ash followed by four short ashed represents an airow index of 04 or that the motor is running
at 4% of capacity.
• Example 4: Nine long ashes followed by an extra long ash represents a ow index of 90 or that the motor is running at
90% of capacity.
■Airflow Configuration
Note: Turn the AirCeil “ON” and let it run for a 15-30 minutes to ensure a clean environment is established when running
the unit in the recirculation mode. Alternatively, a permanently mounted or handheld room pressure monitor can be used to
conrm room conditions meet the latest CDC guidelines for a negative pressure isolation room.
Complete Air Recirculation
1. Install the optional Ceiling Filtered Air Diffuser (Part No. 63841) in a standard 2’ x 4’ T-bar ceiling grid with a 2’ x 2’ blank
off panel.
2. Use clear, exible 12-inch ducting (Part No. 63842) to connect the optional Ceiling Filtered Air Diffuser to the AirCeil
exhaust collar.
3. The AirCeil has the capacity to recirculate up to 600 ft3/min of air.
Note: The actual capacity of the AirCeil will depend on several factors unique to each facility and may include, but shall
not be limited to the length and number of bends in the exible ducting, the type of prelter used and the voltage supplied.
4. The room air change rate the AirCeil unit will generate depends on both the AirCeil airow index setting and the size of
the room. See Table 1 in the Appendix for representative room air changes per hour (ACH).
5. The exibility of placement of the AirCeil unit relative to the Ceiling Filtered Air Diffuser can optimize the needs of the
patient, healthcare workers and the specic activities within the room.
6. Positioning the AirCeil away from the foot of the bed and the Ceiling Filtered Air Diffuser directly above the bed or area of
activity (see Figure 11) allows clean air to be constantly swept across the patient. This may be benecial for an immune
compromised patient.
7. To minimize the spread of airborne contaminants generated by the patient, position the AirCeil toward the head of the bed
and the Ceiling Filtered Air Diffuser downstream from the foot of the bed (see Figure 12). This allows clean air to sweep
past healthcare workers and visitors while removing airborne contaminants generated by the patient.

Installation, Operation, & Maintenance Manual
Total Air Exhaust Mode (Negative Pressure)
1. Attach any 12-inch ducting to the AirCeil exhaust collar.
2. The HEPA ltered exhaust air can be vented either to the outside or returned to the main HVAC system2.
Note: Veried that the ducting and the external exhaust motor/blower can handle the air volume exhausted by the unit.
3. The AirCeil has the capacity to exhaust up to 600 ft3/min of air.
Note: The actual capacity of the AirCeil will depend on several factors unique to each facility and may include, but shall
not be limited to the length and number of bends in the exible exhaust ducting, the type of prelter used and the voltage
requirements.
Initial Start-Up Testing and Certication
Note: The CDC requires that quantitative leakage and lter performance tests be performed at initial installation and every
time the lter is changed or the AirCeil unit moved. These tests should be repeated every 6-12 months. The factory tests
should not be substituted for the initial test.
1. Initial on-site testing and certication of the Hospi-Gard AirCeil is included with the purchase of each unit within the
Continental United States.
Note: Operation of the unit prior to authorized certication may void the warranty.
2. The following services shall be performed at the time of initial on-site testing and certication.
3. Test the HEPA lter quantitatively for leakage and to verify lter performance. Any leaks detected will be repaired or the
lter will be replaced as required.
4. Conrm the maximum capacity of the AirCeil unit is 600 ft3/min ± 10% when the airow index is set on its maximum value
of 100 and the unit free of optional carbon or anti-microbial prelters and any ducting attached to the AirCeil collar.
5. Test ground leakage and ground continuity for electrical safety.
6. Contact an Authorized Service Contractor to arrange a certication date.

■Negative Pressure
CDC guidelines2recommend that rooms used for negative pressure isolation should be single patient rooms with negative
pressure relative to the corridor or other areas connected to the room. The minimum pressure difference necessary to achieve
and maintain negative pressure that will result in airow into the room is 0.001 inch W.G. (a higher pressure is preferred). To
achieve this, the exhaust ow should be 10% or 50 CFM greater than the room supply air, whichever is greater.
Achieving Negative Pressure
Note: It is the responsibility of the purchaser and not ENVIRCO Corporation to ensure the room in which the AirCeil unit
is used to create the negative pressure is in compliance with CDC guidelines2for a negative pressure isolation room and
monitored to ensure its continuing performance.
1. Each AirCeil has the capacity to exhaust up to 600 ft3/min of air.
2. The attachment of ductwork to the exhaust port decreases the air handling capacity of the AirCeil unit. The magnitude of
the decrease will vary depending on the length and type of duct as well as its conguration. For example, a 10-foot run of
standard exible duct containing two 90-degree bends will reduce the exhaust capacity by approximately 100 cfm.
3. A room pressure monitor can be used to conrm the room conditions meet the latest CDC guidelines for a negative
pressure isolation room.

Difculty Achieving Negative Pressure
Note: The AirCeil has the capacity to exhaust up to 600 ft3/min of air, however the actual capacity will depend on several
factors unique to each facility and may include, but shall not be limited to the length and number of bends in the exible
exhaust ducting, the type of prelter used and the voltage requirements.
1. The equipment may not be able to achieve or maintain negative pressure in conformance with the CDC guidelines due to
issues with the existing building ventilation system or air leaks within the negative pressure room.
2. The room should be inspected for any possible source of air leakage through doors, windows, plumbing and equipment

■Optional Accessories
Hospital Grade Power Cord
If purchased with an optional power cord, insert the plug into a properly grounded three pronged receptacle.
Charcoal Prelter
Carbon prelters integrate odor control capabilities to the AirCeil Unit. Carbon prelters help control the odors from cigarette
smoke, perfume, urine and much more. Carbon impregnated lters generally last 30-60 days.
Note: AirCeil Unit can accommodate either the optional charcoal prelter or the optional antimicrobial prelter, but is not
designed to accommodate both.
Antimicrobial Prelter
Antimicrobial treated polyester prelters inhibit the growth of microorganisms (85-90% resistance) on the primary HEPA lters.
These lters should be changed every 30-60 days.
Note: AirCeil Unit can accommodate either the optional antimicrobial prelter or the optional charcoal prelter, but is not
designed to accommodate both.
Ceiling Filtered Air Diffuser
• Required for use in the Total Clean Air Recirculation Mode.
• Fits in a standard 2’ x 2’ ceiling grid section.
UV-C Germicidal Light with Reector
Warning: The Charcoal Prelter must be used with the UV Germicidal Light.
Warning: Never override the safety switch located behind the front panel.
Note: As a safety precaution, the UV Light Safety Switch located just inside the Filter Access Panel door frame will automatically
inactivate the UV Light whenever the Filter Access Panel is opened.
Operating the UV Germicidal Light
• For units with the optional UV Germicidal Light with Reector, locate the “ON/OFF” toggle switch located on the Control
Panel (Figure 3.)
• Press “ON/OFF” toggle switch to the “1” position to turn the UV Light “ON”.
• Press the “ON/OFF” toggle switch to the “0” position to turn the UV Light “OFF.”
Removing the UV Germicidal Light
Caution: The unit must be decontaminated prior to opening the door panel to remove or service the UV Germicidal Light.
Caution: Conrm that the AirCeil Unit is disconnect from its power source before attempting to remove the UV Germicidal Light.
Caution: When removing the UV Light, avoid touching the white HEPA lter pleats. Even a light touch on the lter surface
may damage the lter.
1. Open the Filter Access Panel as described in the Section 6.2.4.
2. Remove the white, green and black wires from the routing clamps on the light reector.
3. Remove the all three UV light wires (white, green and black) leading from the power source to the UV ballast at the
insulated wire connectors (located near the ballast.)
4. Remove the nuts and washer from the end of the light reector channel located on the end opposite the Control Panel.
5. Remove the hardware (nut, screw and washers lock and at) from the Lamp Mount Channel.
6. Carefully, shift the UV Germicidal Light with Reector towards the lamp mount angle until it can be slid to the right (away
from the door hinge.)
Caution: Ensure that the HEPA lter media is not damaged by the UV Germicidal Light as it is removed from the AirCeil Unit.

Calibrating the AirCeil
1. The airow index does not represent the actual airow capacity of the unit. The index represents only the percentage of
capacity at which the motor is operating.
2. The actual air volume generated by the AirCeil should be veried using a calibrated airow measurement device.
3. Determine the room air volume by multiplying the width, length and height of the room in feet.
4. In the air recirculation mode, the CDC recommends that 12 or more air changes per hour (ACH) be established.
5. Multiply the desired ACH (12 or more) by the volume of the room and divide by 60. This is the CFM setting that will provide
the desired ACH for the room.
6. Using a calibrated airow measurement device, set the AirCeil at the airow capacity.
Note: If the desired air capacity cannot be attained, an additional AirCeil may be required.
Air Volume Measurement
• Test Equipment: ShortRidge with 24” X 48” ow hood.
• Test Procedure: Place the ow hood over the intake screen. Take three sets of readings with the airow index set to 100
(full speed.)
Full Speed (airow index at 100)
Uncorrected Corrected
____________ __________
____________ __________

Average of Corrected __________
Acceptable Range: 600 cfm ± 10% on full speed
HEPA Filter Leak Test
Test Equipment
• “DOP” generator with Laskin type nozzles or equivalent
• Aerosol photometer with a linear or expanded logarithmic scale (calibrated)
Test Procedure
1. Set the speed setting index to 55% (5 long ashes – 5 short ashes.)
2. Place the photometer probe in the exhaust collar.
3. Move the aerosol generator hose to all possible leak locations (check the perimeter of the lter seal, the entire lter face
and the back panel of the unit).
4. Acceptance: DOP penetration not to exceed 0.03%.
