The GAS-MHV300 Series Air Sampling Systems are designed for remote unattended continuous air sampling applications. The GAS-MHV300 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 176 CFM (300 m³/hr) or more are attainable with certain glass fiber filter media (depending on the air flow resistance of the filter media). The GAS-MHV300 Series design accommodates rapid field service and component replacement. The clam shell dual hemisphere inlet supports 46cm x 57cm filter media.
For durability and weather resistance, the system is housed in a freestanding powder coat painted aluminum enclosure. The sample air is drawn in under upper hemisphere in an omnidirectional geometry and is exhausted near the bottom of the enclosure. The locking swing door on the enclosure provides convenient access for servicing the equipment inside. A lockable latch of the top cabinet restricts unauthorized tampering of components within the enclosure. The clam shell sample inlet also has a locking mechanism.
