1.1 Introduction
BUFFALO FILTER® ViroVac™ Smoke Evacuation Systems are designed to remove smoke and
noxious odors produced by surgical smoke during laser, electrosurgical, ultrasonic, argon, plasma
and mechanical instrument procedures.
e ViroVac™ Smoke Evacuation Systems have been designed with a high suction, high ow rate
centrifugal action pump. e ultra-quiet motor is used to draw the surgical smoke from the
surgical site through the vacuum tubing and into the ViroSafe lter where the surgical smoke is
processed by a series of lters. A single disposable lter is used to simplify the installation and
removal during lter changes. e lter is completely enclosed to protect the healthcare person-
nel from potential contamination during lter changes. One Bualo Filter ViroSafe lter contains
four dierent stages within to capture the smoke plume.
e rst stage ltration is a prelter whose function is to trap and remove gross particulate and
casual uid.
e second stage ltration is ULPA grade (Ultra Low Penetration Air) lter whose high-tech
patented (U.S. Patent #5874052) design captures particulates and micro-organisms from .1 to .2
microns at an eciency of 99.999%.
e third stage ltration uses the highest grade virgin activated carbon, especially designed for
Bualo Filter for the removal and adsorption of odors and toxic gases produced by burning tis-
sues. ese harmful gases may constitute a health hazard to healthcare professionals who are
subjected to prolonged exposure. e activated carbon used in the ViroVac™ Smoke Evacuation
Systems preferentially removes toxic organic gases rather than water vapor and provides optimal
odor removal.
e fourth stage ltration is an expanded foam used to trap activated carbon nes from migrating
out of the lter.
e electronic controls on the face panel of the ViroVac™ Smoke Evacuation System has been
designed “user friendly” and facilitate unit set up and operation. Please refer to Section 2.0 for
Operating Instructions.
1.2 Inspection
e ViroVac™ Smoke Evacuator has been thoroughly tested and inspected before shipment from
the factory. Please check the unit before using it to insure that no damage has occurred in transit.
If damage is evident, please contact BUFFALO FILTER Customer Service at 1-800-343-2324 (US
Only) or [phone] (International)

10. is equipment needs special precautions regarding ElectroMagnetic Compatibility and
needs to be installed according to EMC information found in this manual.
11. is equipment utilizes mobile RF communications equipment that can aect medical elec-
trical equipment.
12. is equipment has been tested and found to comply with the limits for a Class A digital de-
vice, pursuant to Part 15 of the FCC rules. ese limits are designed to provide reasonable

environment. is equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the
interference at their expense.
13. is equipment operates in the following radio frequency specications:

TX Frequencies: Manchester encoded,
A = fc =/- 423.75kHz, B = fc +/- 484.29kHz
Low bit: transition A to B
High bit: transition B to A
e ViroVac™ Smoke Evacuation System(s) and all lters are not intended for contact with
patients.
1.4 Cautions and Warnings
Please note that all Cautions and Warnings should be read and understood before any use of this
equipment.
Attention, consult Accompanying Documents (Manual)
1.4.1 WARNINGS:
• Read this manual thoroughly, and be familiar with its contents prior to using this equipment.
• Test this equipment prior to a surgical procedure. is product was thoroughly tested at the fac-
tory before shipment.
• Disconnect the unit from the electrical outlet prior to inspecting system components.
• e ViroVac™ system is only intended and suitable for the applications that are mentioned in
the operating instructions.

Bualo Filter ViroVac™ Operator’s Manual: Page 6
• e smoke evacuator produces a strong vacuum. Adjust the airow and the position of the
inlet end of the wand or tubing to prevent patient injury and to prevent suction of surgical
materials and surgical specimens.
• If the smoke evacuator is activated while the airow is set to a high speed, it may produce a
sudden, strong suction action. Check the airow setting before activating the smoke evacu-
ator to prevent patient injury and to prevent suction of surgical materials and surgical
specimens.
• To maximize patient safety, the tubing or wand should not come into direct contact with
tissue. Otherwise, patient injury may result.
• e BUFFALO FILTER ViroSafe lters and single-use accessories are completely disposable.
Please dispose of according to your local codes or regulations and hospital policy. ese lters
may be disposed of or incinerated, whichever is appropriate for your institution.
• Care should be taken to route the power cord, foot pedal, smoke evacuation tubing, and remote
switch activator cable as to not cause a tripping hazard or crimping of cords.
• Do not operate this device in the presence of ammable or explosive gases.
• is equipment is intended for use by healthcare professionals only. is equipment may cause
radio interference or may disrupt the operation of nearby equipment. It may be necessary to
take mitigation measures, such as re-orienting or relocating the ViroVac™ or shielding the loca-
tion.
• e use of ACCESSORIES other than those specied by BUFFALO FILTER, or sold by BUF
FALO FILTER as replacement parts for internal components, may result in increased emissions
or decreased immunity of the ViroVac™.
• is equipment should not be used adjacent to or stacked with other equipment and that if
adjacent or stacked use in necessary, the ViroVac™ should be observed to verify normal opera-
tion in the conguration in which it will be used.
• Refer routine servicing to qualied biomedical technical personnel.
• Changes or modications not expressly approved by Bualo Filter could void the user’s author
ity to operate the equipment.
e warranty on this product is void if any of these warnings are disregarded.

Bualo Filter ViroVac™ Operator’s Manual: Page 7
1.4.2 CAUTIONS:
• Federal law (United States of America) restricts this device to be used by, or on the order of a
physician.
• Do not block either the tubing or the lter. If either becomes occluded or signicantly restrict-
ed, the motor/blower may overheat and cause the unit to fail.
• Using any other lter or accessory not supplied by BUFFALO FILTER may cause damage and/
or cause the system to be inoperable and may void the warranty.
• Care must be exercised in the installation of hoses, adapters and suction canisters. Failure to
follow the procedures outlined in this manual may result in overheating of the motor and may
void the unit warranty.
• is device is not intended for evacuation of uid. If uid is expected to be aspirated to the
ViroSafe Filter, uid collection devices must be installed with the vacuum hose assembly. Fail-
ure to install a uid collection device could cause lter blockage and electrical damage.
• e ViroSafe Filter should be changed according to the life of the lter. e ViroSafe Filter,
used with the ViroVac™ Smoke Evacuation System(s), should not be used for more the time
specied for each lter. Failure to change the lter may result in decreased eciency and
contamination of the electric motor, vacuum pump, and sound absorbing media within the
unit.
• Do not block either the tubing or the lter during operation. An occlusion or signicant restric
tion may cause the motor to overheat and the unit to stop working.
• e installation of this equipment must be on a at, level surface with all four (4) feet in contact
with that surface at all times. Failure to properly install the unit may cause reduced perfor-
mance, damage and/or cause the system to be inoperable and may void the warranty.
• e ambient temperature during operation must be kept between 50°F to 104°F (10°C to
40°C)
• e relative humidity during operation must be kept between 10% to 75%.
• An atmospheric pressure range of 700 hPA to 1,060 hPa.
• Storage environmental ambient temperature 14°F to140°F (-10°C to 60°C).
• Storage environmental relative humidity 10% to 75%.
