APPLICATIONS:
Flexible cabinet ventilation for storage of:
  • Flammable materials
  • Acid / corrosive chemicals
  • Paints
  • Pesticides
  • Hazardous materials

 

 
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 electrostatic 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 self-contained Camfil-Farr HEPA filter is designed to physically capture particles larger than 0.3 microns.

PRODUCT FEATURES:
A. Filtration: Available with Multiplex filtration technology, a unique configuration 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 variety of surfaces.
 
G. Control Panel: Electronic controls and displays include switches for the blower and a low airflow alarm.
 
Vent Box Optional Configurations The Vent-Box is equipped with four intake hose connections, allowing for multiple configurations based on your space and layout requirements. One intake 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 Vent-Box maintains a constant low velocity airflow through the cabinet. Contaminated air is pulled through the Multiplex filtration system where activated carbon adsorbs chemical vapors and/or particulates if HEPA/ULPA filters are used. Clean air is returned to the room.
 
The table below specifies the standard formulations of carbon available within our Multiplex Filtration Technology.
 
Filter Specifications

 
Formula
Description
GP Plus!
The most widely used filter in the range, primarily for solvent, organic, and alcohol removal.
ACI Plus!
Designed to neutralize volatile inorganic acid vapors.
ACR
Iodine and methyl iodide vapors. It is frequently used for iodination reactions with lower level radioactive iodine.
ACM
Mercury vapor
AMM
Removes vapors from dilute ammonia solutions and to remove low molecular weight amines.
SUL
Designed to remove hydrogen sulfide and low molecular weight mercaptans.
CYN
Removal of hydrogen cyanide. Many cyanide compounds will evolve HCN gas which acidifies, so this filter is normally specified if working with any cyanide compound.
FOR
Designed to oxidize formaldehyde and glutaraldehyde fumes.
It is widely used in hospital pathology laboratories.
ETH
Diethyl ether is adsorbed on activated carbon, but because of its low boiling point, the local head adsorption can reduce the capacity of the filter. Special impregnation allows a chemical reaction which increases the filter capacity.
EDU
Designed to handle chemicals normally used in a university level chemistry curriculum.
MIL
As the name implies, this filter is designed for military applications involving war gasses.
HEPA/UPLA
Powders and particulates
