DFPRE 6L Dust Collectors
Dust container assemblies
1. Apply a continuous 5 mm bead of sealing compound to mounting surface of dust
container, along eacht side of the bolt pattern.
2. Bolt dust container to the hopper flange.
The dust container can be moubted to operate from the front, rear or
either side.

Compressed air requirements
DFPRE dust collectors require an independent supply of clean, dry, oil-free
compressed air. Details of pressure and quantity requirements are given in Table 3
(refer to ‘Specification’ section). A design label is also attached to each manifold.
Where an existing factory mains system is to be used it may be necessary to install
an additional moisture separator in the supply line to the collector. If a compressor
is being installed to supply the collector, then the following conditions should be
observed as far as possible:
Type of compressor
Use a compressor of ample capacity – an overloaded compressor may produce
excessively contaminated, moisture-laden air.
Location of air intake
Avoid locating the air intake in an excessively polluted area and install an adequate air
intake filter. The compressor air intake should be sited, if possible, on the north side
of the building – fresh air drawn from the north side is usually cooler and denser, and
therefore has a lower moisture content. (South of the equator the reverse will apply).
Layout and installation of air lines
The pipework between compressor and dust collector should be long enough to
act as a cooling device for the compressed air. A typical requirement for the smaller
installation would be 10 m (30ft) of 12 mm (½” NB) piping. For further details see Table
3. The piping should be installed to provide a fall in the direction of air flow to assist
in the drainage of accumulated moisture. A moisture separator should be provided
at the lowest point of the installation.
