DF-AB-75L-AC Emergency Response Air Sampling System

F&J Model DF-AB-75L-ACThe Model DF-AB-75L-AC is a lightweight, small footprint, DC voltage powered air sampling system operable from (1) line power or (2) a 12-15 VDC power source such as solar panels or other alternative energy sources. The DF-AB-75L-AC is well suited for alternative energy air sampling activities where users do not know whether line power will be available. The unit may be operated from solar power or wind power source through either the AC input (via inverter) 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 lightweight enclosure which is water tight. The unit can be carried very easily by its large, rugged plastic handle.
Typical flow range is 30 - 75 SLPM (2.6 SCFM).
