- Model DF-20L-BL-8 - Brushless Emergency Response Sampling System



F&J Model DF-20L-BL-8 is a lightweight, small footprint, brushless DC motor powered air sampling system operable from (1) on-board 4500 MAH NiMH batteries (2) line power or (3) an external 12 VDC source such as a 12 VDC battery system.

The DF-20L-BL-8 is well suited for indoor air sampling from line power or for remote area air sampling activities where users do have line power available.

The automatic flow control feature with the F&J Digital Flowmeter technology provides maximum flexibility for emergency response or remote and unattended sampling responsibilities. The set flowrate is maintained automatically in case of dust loading and does not require operator attention.
