The DF-60810-MHVE-HSI Series Air Sampling Systems are designed for remote unattended continuous air sampling applications. The DF-60810-MHVE-HSI Series Air Samplers feature a brushless motor with elec-tronic motor speed control that maintains a user selectable flow rate. The flow rate attainable through the filter media is dependent upon the air porosity of the filter media. Flow rate as high as 170 CFM (289 m3/hr) are at-tainable with certain glass fiber filter media. The omni-directional Glass Reinforced Plastic (GRP) hemispheri-cal sample inlet design provides improved sample collection efficiency.
The DF-60810-MHVE-HSI Series design accommodates rapid field service and component replacement. The basic components of the system are assembled in a modular fashion so that each component can be readily and independently removed for service.
For durability and weather resistance, the system is housed in a freestanding powder coat painted aluminum enclosure. The sample air is drawn in under the 360° omni-directional hemispherical sample inlet and is ex-hausted near the bottom of the enclosure. The locking swing door on the enclosure provides convenient access for servicing the equipment inside. A lockable latch on the hemispherical sample inlet restricts unauthorized tampering with the filter holder.
