The DF-PM10DTE high volume PM10 Air Sampling System is designed for remote unattended continuous air sampling applications. The DF-PM10DTE Air Sampler features 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 20.3 cm × 25.4 cm (8” × 10”) filter media. The DF-PM10DTE 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. The DF-PM10DTE system can easily be converted to a TSP system with the proper accessories.
For durability and weather resistance, the system is housed in a freestanding powder coated epoxy finished aluminum enclosure. The sample air is drawn into the size selective inlet head from a full 360° radius and is exhausted near the bottom of the enclosure. The locking swing door on the enclosure provides convenient access for servicing the equipment inside.
The electronic flow control measurement sub-system of the DF-PM10DTE air sampler provides a corrected flow measurement to a reference T and P or ambient conditions. The air flow is measured by a precision-machined differential pressure sensor. The controller can be set to a maximum sampling flow rate up to ~100 CFM (~170 m3/hr) depending on the filter paper air resistance. The bright LED readout displays multiple air sampling information including current flow rate, current elapsed sample time and totalized volume. The DF-PM10DTE model utilizes an 20,3×25,4 cm (8”×10”) filter media.
