■Introduction
Description
The THRC is a portable, self-contained high efficiency particulate air (HEPA) filtration system with an optional
ultraviolet lamp that helps to disinfect the filter face. The THRC is designed to easily and economically create a negative
pressure isolation room that will meet OSHA and CDC TB guidelines. The THRC can be used as a positive pressure clean
air recirculating system in clinics, waiting rooms, hospital emergency rooms and other confined areas or as a partial or
complete exhausting system to create a negative pressure isolation room for possible use with patients known or
suspected of having TB, SARS, COVID-19, or other infectious diseases. The THRC is available in two different sizes: the
THRC Low Flow (LF) and the THRC High Flow (HF). As a recirculating unit, the THRC’s powerful motor/blower can deliver
up to 370 CFM (628 m3/hr) for the THRC LF and up to 800 CFM (1360 m3/hr) for the THRC HF to provide a large number
of room air changes per hour to minimize the spread of airborne diseases to patients and health care workers. As a
negative pressure unit, the air passing through the HEPA filter is filtered of 99.99% of particles at 0.3 micron and may be
exhausted directly to the exterior through a window, or through a wall, simply by connecting flexible ducting to the 6 in. (152
mm) collar located on the top of the THRC.
Features
• Low Cost Isolation Room
The THRC is an easy and economical solution for creating a negative pressure isolation room. Simply roll the
THRC into a standard room, connect flexible ducting to the 6 in. (152 mm) collar on the top of the unit for partial
exhaust or to the optional 8 in. (204 mm) flanged collar for total exhaust, and vent the purified air to the exterior through
a window or wall.
• Flexible Applications
The versatile THRC can be used as a clean air recirculating unit, a negative pressure unit, or as a split system to
create both negative pressure and clean air recirculation by simultaneously exhausting some of the air out while
recirculating the remainder back into the room.
• Small and Portable
The THRC can be rolled from one room to another and easily fits into areas with limited floor space.
• Simple Maintenance
Both HEPA filter and prefilter are easily accessible for replacement by authorized personnel.
•Adjustable Airflow
The THRC provides effective air filtration for a wide variety of room sizes. The THRC LF utilizes a solid state speed
control with airflows ranging from 70 to 370 CFM (118 to 628 m3/hr). The THRC HF utilizes a three position switch with
airflows ranging from 560 to 800 CFM (951 to 1360 m3/hr).
• Low-High Clean Air Circulation Pattern
Room air, along with airborne contaminants, is drawn into the intake grill at the bottom while the purified air is discharged
at a high velocity from the exhaust grill located at the top of the THRC to generate a sweeping, low-to-high air
circulation pattern with adequate “reach” to optimize the clean breathing zone for patient and staff.

■Operation
Initial Start-Up
1. Connect the power cord to a standard 115-Volt, Single Phase, 60 Hertz, or 220-Volt, 50/60 Hertz, grounded power source.
Verify that the circuit is sized to provide sufficient amperage as noted on the THRC data plate.
2. Locate the “ON/OFF” switch on the right side of the unit. The switch is a maintain contact rocker type.
3. Turn the THRC unit on by pressing downward on the raised portion of the rocker switch. A light whirring sound will be
heard as the motor starts. Within 5 to 10 seconds, the module will start to provide clean air into the environment.
Speed Adjustment
Note: THRC HF unitsare set on high speed at the factory. TLRC LF units are set to OFF.
1. To change speeds, remove the supply grille by pulling down and lifting out.
2. Turn the 3-speed switch (or solid state speed control) to the desired setting on the THRC HF or LF.
3. Replace the supply grille when finished.
Filter Change Indicator
1. Locate the airflow indicator on the right side of the unit above the “ON/OFF” switch. On high speed, the light will turn on
when there is insufficient pressure, indicating the need for a filter change. It is recommended to change prefilter. If the
filter change indicator light is still illuminated, it is recommended to replace the HEPA filter. The airflow indicator should
not be used as the only guide for when a filter change is necessary. The unit should be checked at each use to ensure
recommended room air changes per hour are being met.
2. The filter change indicator light can be adjusted by adjusting the pressure switch which can be seen on the back panel of
the THRC. For setting the light, block the lower intake grill approximately 75% while the unit is on high speed. The
pressure switch should be set to have the light flicker while covered 75%. Once the restriction is removed, the light should
go off. If the intake grille is completely covered, the light should be solid on.
3. The air velocity generated by the unit may be checked using an airflow measurement device. For the THRC HF the
volume of air entering the lower intake grille should be approximately 560 CFM (951 m3/h) on low, 690 CFM (1172
m3/h) on medium, and 800 CFM (1359 m3/h) on high with a new filter. Air volume on the THRC LF should be
approximately 70 CFM (118 m3/h) to 370 CFM (628 m3/h) depending on the position of the speed control with a new filter.
Recirculation Mode
1. The THRC unit is set at the factory on the 100% air recirculation mode.
2. The room air change rate of the unit will depend on both the THRC speed setting and the size of the room.
3. For maximum recirculation efficiency in a patient room, the unit should be placed between the entry door and the patient’s
bed or the activity area (see Figure 1 below). However, the unit will function effectively at other locations within the room.

THRC HF & LF
Partial Exhaust/Recirculation Mode
Note: The THRC units come with a removable Exhaust Cover Plate and a removable 6-inch (152mm) Duct Collar for
attachment to exhaust ducting (not included) to create a negative pressure room. lf the Exhaust Cover Plate is not
removed, the THRC units will operate in the 100% recirculation mode.
1. Remove the Exhaust Cover Plate located on top of the lsoClean® unit by taking off the four (4) screws and plastic caps
used to secure the cover to the THRC exhaust port.
2. Remove the 6-inch (152mm) duct collar underneath the top cover and flip the collar over.
3. Attach exhaust ducting (not included) onto the collar and fasten tightly with a round hose clamp (not included).
4. Mount the duct collar with ducting onto the THRC exhaust port using the four (4) screws that originally held the cover
plate. Note: Keep the top plate and plastic washers for re-assembly when needed.
5. The HEPA filtered exhaust air can now be vented to the outside or returned to the main HVAC system1. lf the unit is ducted
to an exhaust duct rather than directly to the outside, it must be verified that the exhaust duct is capable of handling the
exhaust air expelled by the unit.
6. The lTHRC is designed to exhaust 100-300 CFM for the High Flow and 25-150 CFM for the Low Flow at the 6-inch
exhaust port. lt is recommended that the unit be set on the high-speed setting when operating in this mode to achieve
maximum exhaust and negative pressure. At this setting, the THRC will exhaust approximately 300 CFM (510 m3/h) and
recirculate 500 CFM (850 m3/h) for the High Flow and exhaust approximately 150 CFM (254 m3/h) and recirculate 220
CFM (373 m3/h) for the Low Flow.
Total Exhaust Mode (Negative Pressure)
CAUTION: To reduce risk of re and to properly exhaust air, be sure to duct air outside - Do not vent exhaust air into
spaces within walls or ceilings or into attics, crawl spaces, or garages.
CAUTION: For General Ventilating Use Only. Do Not Use to Exhaust Hazardous or Explosive Materials and Vapors.
Note: The cover plate must be securely attached to the top of the THRC for the unit to run in the 100% exhaust mode.
An optional 8-inch (203mm) Exhaust Collar with Flange is available to convert the THRC unit to the 100% exhaust mode.
1. Remove the front exhaust grille by pulling down and lifting out.
2. Place the optional 8-inch (203mm) exhaust collar over the opening where the grille was removed and attach with the
screws included with the 8-inch collar.
3. Attach exible exhaust duct (not included) over the 8-inch collar and fasten tightly with a round hose clamp (not included).
4. The HEPA ltered exhaust air can now be vented to the outside or returned to the main HVAC system1. lf the unit is ducted
to an exhaust duct rather than directly to the outside, it must be veried that the exhaust duct is capable of handling the
exhaust air expelled by the unit.
Negative Pressure
NOTE: CDC GUIDELINES RECOMMEND 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 TOACHIEVE AND MAINTAIN
NEGATIVE PRESSURE THAT WILL RESULT IN AIRFLOW INTO THE ROOM IS 0.01 INCH W.G. (2.5PA) (A HIGHER
PRESSURE IS PREFERRED). TO ACHIEVE THIS, THE EXHAUST FLOW SHOULD BE 10% OR 50 CFM (85 M3/H)
GREATER THAN THE SUPPLY (WHICHEVER IS GREATER).
Achieving Negative Pressure
1. The THRC unit is designed to exhaust 100-300 CFM (High Flow unit) or 25-150 CFM (Low Flow unit) when the 6-inch
(152.4mm) exhaust collar is used. lt is recommended that the unit be set on the high-speed setting when operating in
this mode to achieve maximum exhaust and negative pressure.
2. lf an exhaust volume greater than 300 CFM (800 unit) or 150 CFM (400 unit) is required to create a negative pressure
room, the optional 8-inch (203.2 mm) 100% exhaust collar should be used.
3. The attachment of ductwork to the exhaust port decreases the air volume exhausted through the port. The magnitude of the
decrease varies depending on the length and type of duct as well as unit configuration.
1 CDC recommends that air from negative pressure rooms be exhausted to the outside in accordance with federal, state, local or country regulations.
The air should not be recirculated into the general ventilation. ln certain cases in existing facilities, recirculation of air into the general ventilation system
is unavoidable and, in such cases, CDC guidelines state that HEPA lters should be installed in the exhaust duct leading from the room to the general
ventilation system.
