CONSTUCTION
CABINET Outer casing of the RFC is constructed from galvanized steel, powder-coated to AS2700. The work zone is constructed in Grade 304 stainless steel. A removable aluminium screen is fitted in front of the prefilter at the rear of the work zone. FAN A direct drive motor/blower is regulated by a variable speed controller to enable airflows to be maintained through filter life.
ELECTRICAL 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. Glare-free fluorescent lamps provide a minimum lighting intensity of 800 lux at the work surface. 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.
PREFILTERS An easily-accessed, disposable polyester prefilter arrests not less than 90% of particulates > 5μm, thus prolonging carbon filter life. A warning light in the control panel signals the need for prefilter service.
