The CF-24B, FIXED SPEED, 12/24 VDC external battery operated field unit is ideal for remote site grab sampling. An elapsed, resettable timer (with independent 5 year battery) is incorporated into the unit housing to track exact sampling duration. The throughput flow rate is dependent upon the pressure drop across the filter media and the supplied voltage (12 or 24 volts DC). The CF-24B includes a 1½” female straight pipe fitting which accepts the “CF” series filter holders. See “Air Sampling Accessories” section of this catalog for optional 12/24 Volt DC Portable Power Source (P/N: PPS-12/24-VDC).
