F&J Model DF-40L-400-Li is a lightweight, small footprint, DC voltage powered air sampling system operable from (1) on-board 20 Ah Li Ion battery, (2) line power, or (3) auxiliary DC connector (12 – 15 VDC) The DF-40L-400-Li 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 battery is approximately 18 - 20 hours utilizing FP47M 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 dimensioned 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).
