Purair Basic Ductless Fume Hoods
Advanced carbon filtration technology offers a safe, high performance alternative to conventional ducted fume hoods for a broad range of applications.
Air Science® ductless fume hoods isolate and trap chemical vapors to prevent ecological impact through release into the environment.
Each filtration system is selected for its specific application. Carbon filters are available in more than 14 configurations for use with vapors of organic solvents, acids, mercury and formaldehyde.
HEPA/ULPA filters can be added for biological safety.
The ductless fume hood is self-contained and does not require venting to the outside. Many units are portable and may be moved with minimal downtime and without filter changes. Set-up, operation, and filter maintenance are straightforward. It's easy to install.
It is energy efficient. Because filtered air is returned to the room, no demands are required of the facility HVAC capacity for make-up air.
Facility ductwork, HVAC and construction costs are eliminated. Cabinet airflow and face velocity protect users from incidental exposures to fumes, so it is safe to use.
A. Filter I.D. Window: A convenient, strategically placed front cover window shows the installed filter part number and installation date to encourage timely filter replacement.
B. Control Panel: Electronic controls and displays include switches for the blower and filter blockage alarm.
C. Filter Blockage Alarm: Continuously monitors filter loading and alerts user when service is needed.
D. Air Velometer: An optional analog air velocity meter is positioned in the user's field of vision.
E. Steel Support Frame: The chemical resistant epoxy coated steel frame adds mechanical strength. Optional all polypropylene construction is available if desired; see accessories.
F. Hinged Front Sash: When closed, the cabinet sash protects the contents from inadvertent external contact and better isolates the air within. The sash is easy to open and close.
G. Work Surface: The internal work surface can be fitted with an optional polypropylene (available in white and black) or stainless steel tray; see accessories.
H. Pass Through Ports: Electrical cords and cables are safely routed into the cabinet through ports on the back.
I. Electrostatic Pre-Filter: The electrostatic pre-filter is accessible from inside the chamber and 91% effective down to 1-3 microns.
J. Filter Door Key: Filter access keys prevent unauthorized removal or accidental exposure to dirty filters.
K. Dynamic Filtration Chamber: The dynamic filter chamber prevents any possible leakage of contaminated air by pressurizing the fan plenum (positive air) and depressuring the filter compartment (negative air).
L. Internal Manual Speed Controller: Authorized personnel may set the EC blower speed as desired.
M. Stand: Optional mobile cart with locking casters.
N. Safety Filter: The optional carbon or HEPA/ULPA safety filter adds an additional layer of protection.
360 Degree Visibility: Clear back and side panels allow ambient illumination into the chamber and provide users with an unobstructed view of its contents.
Construction: All models are available in either metal or polypropylene construction. See selection chart for specifications and dimensions. Specify metal or polypropylene when ordering. Available in 110V, 60Hz or 220V, 50Hz models.
Steel Support Frame: The chemical resistant epoxy coated steel frame adds mechanical strength. Optional all polypropylene construction is available if desired.
