CF-995B: Variable Speed, Internal Battery & Charger, AC/DC Relay

Variable Speed, Internal Battery Powered, Portable Air Sampler

HI-Q has incorporated a high efficiency, variable speed circuit in its CF-995B, battery operated air sampler series which allows its users to preset flow rates by varying the blower motor speed. The CF-995B & CF-995B-4 are ideal for adjustable flow, remote location air sampling where AC line power is not available. An internally mounted battery and battery charger eliminate the need for the transportation of cumbersome battery cables and the awkward handling of heavy batteries. A 10-function, panel-mounted programmable timer allows the user to preset a wide range of sample times and cycles. The maximum settable flow rate of the CF-995B series air samplers is dependent upon the pressure drop across the collection filter media being used. An internally mounted, automatic AC/DC relay switch, allows the CF-995B series air samplers to also be used continuously when AC power is available. Upon Ordering, please specify intended filter media type and size.
