F&J - Model DF-60810-MHV - Mega High Volume Air Sampler System (100 – 120 VAC)
The DF-60810-MHV Series Air Sampling Systems are designed for remote unattended continuous air sampling applications. The DF-60810-MHV Series Air Samplers feature a brushless motor with electronic 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 175 CFM (300 m3/hr) are attainable with glass fiber filter media.
The DF-60810-MHV 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 eaves of the hinged lid from all four sides 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 on the top cover restricts unauthorized tampering with the filter holder.
The electronic flow control measurement sub-system of the DF-60810-MHV Series provides a reference standard flow measurement and an operator selectable constant flow of air through the filter medium. The air flow is measured by a precision-machined differential pressure sensor. The controller can be readily set to any sampling flow rate between 50 and 175 CFM (84-300 m3/hr) depending on the filter paper air resistance and dimensions.
The bright LED readout displays multiple air sampling information including current flow rate, current elapsed sample time and totalized volume. The filter holder can be custom designed to accommodate any filter size and type. The DF-60810-MHV standard model utilizes an 8”×10” (20.3×25.4 cm) filter.
