F&J Model DFRV-ABM50-40L-20Li is a lightweight, small footprint, rotary vane AC/DC powered air sampling system operable from (1) line power, (2) the on-board 20 Ah LiFePO4 battery, or (3) an external 12-15 VDC power source.
The DFRV-ABM50-40L-20Li is well suited for alternative energy air sampling activities. The unit may be operat-ed from solar power or a wind power source through either the AC input or DC input.
The automatic flow control feature with the F&J Digital Flowmeter technology provides maximum flexibility for emergency response sampling responsibilities. The set flowrate is maintained automatically in case of dust loading and does not require operator attention. The air sampler is contained in a rugged, metal, small dimen-sioned enclosure which is water tight. The unit can be carried very easily by its metal handle.
Typical flow range is 5 – 40 SLPM (0.2 –1.41 SCFM). This flow rate varies by the filter media utilized. If pres-sure drop across the filter media is not significant lower flow will not be achievable without bypass valve op-tion.
The air sampler is also equipped with internal data storage that allows the user to download the sampling data as a .csv file for easy data analysis.
