The DF-1515DT Series Air Sampling Systems are designed for remote unattended continuous air sampling applications. The DF-1515DT Series Air Samplers feature a brushless motor with electronic motor speed control that maintains a user selectable flowrate. The flowrate range attainable through the filter media is de-pendent upon the air porosity of the filter media. The DF-1515DT 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.
The electronic flow control measurement sub-system of the DF-1515DT Series provides a standard flow measurement and a 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 20 and 70 CFM (560-1980 LPM) 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-1515DT model utilizes an F&J low profile 8”×10” (20,3×25,4 cm) filter.
