INTRODUCTION
Air Science Vent-Box™ ductless filtration
systems are designed to protect
laboratory personnel from chemical
vapors found inside of stand alone
chemical safety cabinets. The Vent-Box
serves as modular ventilation and a
filtration system for all chemical
safety cabinets.
AIR SCIENCE
MULTIPLEX FILTRATION
TECHNOLOGY SYSTEM
The Vent-Box utilizes the
exclusive Air Science
Multiplex filtration
system, a unique configuration that includes
a pre-filter and main filter
to create a chemical,
physical or combination
architecture to adsorb,
neutralize or trap the
target chemicals or
particulate. Fumes are
pulled via a flexible
hose connected to the
cabinet and clean,
filtered air is returned
to the laboratory,
eliminating the need
for external ducting
and minimizing loss of
treated, conditioned air
from the facility.
MULTIPLEX
SYSTEM FILTERS
• Pre-Filter. The electro-
static pre -filter protects
the main filters from
aerosols, dust and
particulates with filtration efficiency superior
to 95.5% down to 0.5
microns.
• Main Filter. Activated
Carbon FILTCO
sourced. A single
carbon filter containing
chemically-formulated
activated carbon granules is selected when
ordering to accommodate a specific vapor
or family of vapors.
• HEPA Filter. A selfcontained Camfil-Farr
HEPA filter is designed
to physically capture
particles larger than
0.3 microns.
™
This Product Exceeds OSHA, ANSI and Other International Standards.

Modular Ventilation and Filtration System
PRODUCT FEATURES:
A. Filtration: Available with Multiplex filtration
technology, a unique configuration that includes
a pre-filter and main carbon filter. HEPA/ULPA filtration is also available.
B. Hose: Each unit is provided with a 1 meter
PVC or metal flex hose with smooth inner surfaces
to minimize pressure drop and friction loss.
C. No-Tools Filter Access: The filter is easy to
replace, no tools required. Simply open the easy
access lid and change the filters.
D. Multiple Connection Configurations: The
Vent-Box comes equipped with four possible intake
connections, allowing you to easily configure the
unit to meet your space requirements.
E. Exhaust Port: Slotted exhaust port allows
for an optional bolt-on ducting collar that allows
connection to existing in-house ductwork.
F. Leveling Feet: Equipped with adjustable
leveling feet that ensure solid placement on
a variet y of surfaces.
G. Control Panel: Electronic controls and displays
include switches for the blower and a low airflow
alarm.

The Vent-Box is equipped with four intake hose connections, allowing for multiple configu rations based on your space
and layout requireme nts. One inta ke hose connection is located on either side of the Vent- Box top frame, with two
connections located on the rear portion of the frame. Cover plates are available for the unused connection ports.

AIR SCIENCE
CARBON FILTRATION
Air Science carbon
filters are based on
enhanced, activated
carbon particle formulations from naturally
occurring raw material
superior to wood or
other organic sources.
Our carbon is treated
to attain the proper
porosity and aggregate
surface area, while
reacting with several
ranges of aerosolized
chemicals moved
through the filter by an
air handling blower.
The table below
specifies the standard
formulations of carbon
available within our
Multiplex Filtration
Technology.
