HI-Q’s CF-993B & CF-993B-4 are ideal for remote location air sampling where line power is not available. An internally mounted sealed 12 Volt battery and battery charger eliminate the need for the transportation of cumbersome battery cables and the awkward handling of heavy batteries. The timer has 10 programmable timing functions with a wide time range. The flow rate of the CF-993B series air samplers are dependent upon the pressure drop across the collection filter media being used. If line power is available, sampling time can be extended by running line voltage to the charger while sampling. Due to the difference in Amp draw of the motor versus amperage output of the charger in the standard CF-993B, the unit will eventually stop running and need to be fully recharged. Upon Ordering, please specify intended filter media type and size.

Continuous AC powered air sampling is now possible on the CF-993B & CF-993B-4 with the addition of HI-Q’s optional, internally mounted, AC/DC RELAY. The AC/DC Relay can be added to existing, or supplied with new units to allow continuous sampling where AC Power is available.
