DFPRE 6L Dust Collectors
Pressure relief
The manifold has a maximum design pressure of 8 bar (see Table 2 in ‘Specifications’
section). It is a requirement that adequate protection is made not to exceed this
pressure.
We advise to install a pressure regulator - oil/water separator to regulate
the compressed air and to ensure the compressed air is free from oil and
condensate.
Controller
It is a requirement of the Supply of Machinery (Safety) Regulations 2008 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 DFPRE dust collector is supplied with a factory fitted Powerbox to operate the
fan and the compressed air cleaning system.
For controller connections and set-up, refer to the controller manual.
Details of standard fan motor supply voltage are given in Table 4 (refer to
‘Specification’ section).
Overload protection
All feeder circuits should be adequately protected with suitably-rated fuses and
contactors with integral overload protection.
Installation check list
Where applicable, ensure that the collector is securely bolted to the floor.
Ensure compressed air supply is free from leaks, installed correctly and
according to the compressed air specifications, Table 2 and 3.
Ensure electrical supply is installed correctly and complies to local legislation.
Ensure all the electrical components are complying with the zone where they
are installed.
