F&J Model DF-AB-40L-5Li is a lightweight, small footprint, DC voltage powered air sampling system opera-ble from (1) on-board LiFePO4 battery, (2) line power, (3) vehicle cigarette lighter socket or (4) from the F&J LIBATBANK-12V.
The DF-AB-40L-5Li is well suited for emergency response sampling activities where users do not know whether line power will be available. Typical operating time from on-board batteries is approximately 6 hours utilizing F&J FP47M (47 mm) glass fiber filter paper.
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 lightweight small dimen-sioned enclosure which is water tight. The unit can be carried very easily by its large, rugged plastic handle.
Typical flow range is 10 – 35 SLPM (0.3 -1.24 SCFM).
