F&J - Model DF-804DT-30 -Enzyme Dust Sampler with Casters (100 – 120 VAC)

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 horizontally into the filter holder from all four sides and is exhausted near the bottom of the enclosure. The locking swing door of the enclosure provides convenient access for servicing the equipment inside.

The electronic flow control measurement sub-system of the DF-804DT-30 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 5 and 50 CFM (141-1415 LPM) depending on the filter paper air flow 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-804DT-30 model utilizes a 15 cm diameter filter.
