- Model DF-EDL-22E Series - Elite Digital Light (EDL) Air Sampler



The DF-EDL-22E environmental air sampling system with digital flowmeter is a low-volume air sampler consisting of brushless centrifugal blower with automatic electronic flow control. The vacuum air movement system is mounted on a removable base plate, which can be secured within the GFCI protected aluminum environmental weatherhouse, Model WH-3 having an enclosure rating of IPX3. The digital flow meter has a large bright LED display.

The DF-EDL-22E environmental air sampling system is designed for continuous outdoor use. Please consult the product specifications for the design temperature range and the installation category. The standard product displays flow rate, elapsed time and totalized volume by operator selection. The typical operating range is 0.5 to 4 CFM (14 – 115 LPM).
