PURAIR® VERTICAL AIRFLOW
-
Room air enters from the top of the cabinet through a disposable pre-filter; this traps larger particles and increases filter life. -
Air is forced evenly across the ULPA filter in a stream of clean, uniform air within the work zone. This dilutes and flushes airborne contaminants from the interior.
-
A nominal filter face velocity of 0-45 m/s (90 fpm) ensures a sufficient number of air changes to maintain cleanliness within the work zone.
-
The purified air travels down to the work zone in a vertical, unidirectional down flow stream, exiting the work zone across the entire open cabinet front area after deflecting off the work surface. Rear wall perforations are designed to reduce work surface turbulence and minimize the possibility of dead air corners in the work zone.
PURAIR® HORIZONTAL AIRFLOW

 |
FEATURES AND BENEFITS
-
Purair® Laminar Flow Cabinets are available in 2 model types with various sizes and options for a total of 11 standard models.
The main filter gasket evenly seals the filter face to prevent bypass air leakage. Our pour-in-place silicone gasket out performs traditional style stick-on "dove-tail" gasketing. -
Purair® Laminar Flow Cabinets are shipped fully assembled. No installation is required; just plug them in and use them.
-
Products are designed for desktop use, or may be installed on an optional mobile base stand.
-
The rear wall of vertical flow cabinets is perforated to reduce work surface turbulence by removing some of the airfl ow to the rear.
-
Horizontal flow cabinets are designed with a lip on the rear of the work surface to protect the ULPA filter from spills.
-
High capacity air handling system delivers flow velocity of 0.45 m/s or 90 fpm.
-
Purair® VLF and HLF cabinets have an ULPA filter pressure gauge to measure filter performance.
-
The Air Science® filters are easy to access, easy to change.
-
Purair® Laminar Flow products are constructed of steel with Air Science's exclusive MICROgone anti-microbial powder finish coating.
-
Accessories include an IV bar, service fixtures, base stand, UV lamp, and front door/cover.

Purair® Laminar Flow Cabinets maintain a 0.45 m/s or 90 fpm airflow velocity, measured 6"/150mm from the filter with a uniformity of +/- 20% across the filter face. This face velocity is in compliance with USA and international standards for safety and performance. The ULPA filters are easy to replace with common tools.Air Science® laminar flow cabinets incorporate ebmpapst permanently lubricated direct drive centrifugal blowers. The energy efficient design reduces operating costs and has extremely low noise and vibration levels.
