Dust Collectors - Series CPV
Type of compressor
Use a compressor of ample capacity – an overloaded compressor tends to 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 10m (30ft) of 12mm (½” NB) piping. For further details see Table
4. 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.
Pressure relief
The manifold has a maximum operating pressure of 6.2 bar (see Table 3 in
‘Specifications’ section). It is a requirement that adequate precaution is taken to
avoid exceeding this pressure. Where a relief valve is supplied by Donaldson this
device has a relief rating of 17 dm³/s at 6.9 bar. Extra system relief will be required
if the connected supply can exceed this.
Controller
It is a requirement of the Supply of Machinery (Safety) Regulations 1992 to
provide adequate isolation and emergency stop facilities. Due to the varied
nature of site installations this cannot be provided by Donaldson but instead
is the responsibility of the customer.
Always isolate power before opening the controller.
Each CPV dust collector is supplied with a Controller or a Power Box to operate the
compressed air cleaning system. The Power Box also operates the fan.
For Controller connections and set-up, refer to Controller manual.
Collectors with integral fan
When the collector is fitted with a Controller, the fan will be wired to the terminal
box located on the front of the collector. These terminals will need to be wired to a
suitable control panel for the type of fan motor supplied. This control panel should
be designed to comply with local legislation for electrical installations (refer also to
‘Overload protection’ and ‘Control of ancillary equipment and interlocks’).
When the collector is fitted with a Power Box, the fan will be wired to the Power Box.
Connect the incoming three-phase supply to the isolator of the Power Box.
Details of standard fan motor supply voltage are given in Table 5 (refer to
‘Specification’ section).
Overload protection
All feeder circuits should be adequately protected with suitably-rated fuses and
contactors with integral overload protection.
