EMERGENCY RESPONSE SAMPLING SYSTEM 

—

 

Digital Flowmeter Technology — 

F&J Model DF-75L-Li 

 

                                     

 

 

 

 

GENERAL DESCRIPTION: 

F&J Model DF-75L-Li is a lightweight, small footprint, DC voltage powered air sampling system operable 
from (1) on-board 14.8 VDC; 15.6 Ah Lithium ion battery, (2) line power, or (3) automobile cigarette lighter 
socket. 
 
The DF-75L-Li is well suited for emergency response sampling activities where users do not know whether 
line power will be available and for alternative energy power source applications when line power is not 
available. 
 
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. 
 
Typical flow range is 30-75 SLPM (1.1 -2.6 SCFM).
