The DF-ERHV-DT-CFH Series Air Sampling Systems are designed for temporary or emergency response contin-uous air sampling applications. The DF-ERHV-DT-CFH Series Air Samplers feature a brushless motor with elec-tronic 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 and its dimensions. The flow rate range attaina-ble through the filter media is dependent upon the air porosity of the filter media and its dimensions. The DF-ERHV-DT-CFH 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 flex-ible plastic hose. The DF-ERHV-DT-CFH model utilizes circular filter media. Filter holder options include 102mm, 110mm, 120mm, 125mm, 130mm, 140mm and 150mm.
