1.1 Introduction
BUFFALO FILTER® ViroVac Smoke Evacuation Systems are intended to evacuate and lter surgi-
cal smoke plume and aerosols created by the interface surgical tools with tissue, examples being
lasers, electrosurgery systems, and ultrasonic devices.
e ViroVac Smoke Evacuation Systems have been designed with a high suction, high ow rate
vacuum motor. 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 personnel 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.
