Description
Operation
Recirculating CSV modules utilise a direct drive fan that draws ambient air into the cabinet from the air intake that is located under the viewing window. Air passes through the perforated storage shelves and into the exhaust filter system, consisting of two stages of filtration, prior to being recirculated into the room. The first stage prefilter arrests > 90% of particles 5 micron and larger. The final activated carbon filter incorporates carbon granules with a selected chemical impregnation to optimise the arrestance of specific vapours. Specific impregnations are available for the handling of a wide range of contaminants.
The contaminants include:
– Formaldehyde and glutaraldehyde
– Alkaline odours
– Ammonia and amines
– Inorganic acids and acidic odours
– H2S and mercaptans
– HCN
Cabinets operate on single-phase 240V, 50 Hz power via a 10A outlet. A low voltage touch control panel with function status indicated by LEDs is located on the front of the cabinet. An audible alarm indicates low air flow within the cabinet.
Ducted models are designed to work with building services and can be fitted with additional filtration systems.
On-Site Testing
Products produced by AES are factory tested to ensure compliance and performance targets are met. Additional testing and certification is recommended as follows: – On-site prior to use – After any electrical of mechanical maintenance – After filter replacement – After re-location – At least annually – In special circumstances, e.g. if faulty operation is suspected. AES Environmental is a NATA registered laboratory that provides comprehensive on-site maintenance, testing and certification services of safety cabinets, laminar flow work stations, cleanrooms, operating theatres and HEPA filter installations.
How to Specify
