The DF-ERHV-DT Series Air Sampling Systems are designed for temporary or emergency response continuous air sampling applications. The DF-ERHV-DT Series Air Samplers feature a brushless motor with electronic motor speed control that maintains a user selectable flow rate. The flow rate range attainable through the filter media is dependent upon the air porosity of the filter media. Flow rates as high as 136 m3/hr (80 CFM) are attainable with glass fiber filter media. The DF-ERHV-DT Series design accommodates rapid field service and component replacement.
For mobility, the air sampler is housed in a rugged weather resistant polypropylene enclosure with wheels and multiple handles. The tripod, accessories and consumables are stored in an identical heavy duty polypropylene case. The air sampler is connected to the discharge port of the filter holder mounted on the tripod by a rugged flexible plastic hose. The DF-ERHV-DT model utilizes an 8”×10” (20,3×25,4 cm) filter. The 8” x 10” (20,3cm x 25,4cm) filter holder is stored in its own enclosure.
