Model GAS-ERHV-DTE-CFH -Emergency Response Mobile High Volume Air Sampling System
The GAS-ERHV-DTE-CFH Series Air Sampling Systems are designed for temporary or emergency response continuous air sampling applications. The GAS-ERHV-DTE-CFH 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 and filter media dimensions. Flow rates as high as 119 m3/hr (70 CFM) are attainable with certain glass fiber filter media. The GAS-ERHV-DTE-CFH Series design accommodates rapid field service and component replacement.· Precision machined DP flow sensor
