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