Page 4: Safety Recommendations
Delivery is an integral part of the manual. Other items of equipment, not supplied under the Scope of Delivery from Donaldson, should be installed, operated and maintained according to the documentation supplied with the respective equipment. Any modification carried out on the ‘as supplied’ equipment may reduce reliability and safety, and will nullify warranty;... - Page 5 Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® Compressed air is recommended for collectors that operate using reverse jet cleaning. Alternative gases should be assessed before use to ensure that explosive atmospheres are not introduced during media cleaning. Where the equipment supplied is suitable for working within a potentially explosive atmosphere (as defined by Directive 2014/34/EU) it will be according to the categories and conditions marked on the collector serial nameplate.
- Page 6 Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® None of the fan assemblies can be considered to be a fully sealed design, indeed most are arranged with either an open inlet or an open outlet. For this reason, the internal and external atmospheres can be considered the same in terms of any potentially hazardous classification.

Page 8: General Guidance To Lifting
This can be achieved by applying a continuous 5 mm bead of sealing compound to the mounting surface, along each side of the hole pattern. For non-Donaldson equipment please also check supplier’s IOM manual for any specific requirements. As mist particles coalesce and form larger droplets, the droplets become large enough to run down the filter element. -
Page 9: Mounting Over Aperture
Match up fixing-holes, install bolts, washers and nuts and tighten down all round to form an airtight seal. Fixing bolts etc. are not supplied by Donaldson. Compressed air requirements PowerCore dust collectors require an independent supply of clean, dry, oil- free compressed air. -

‘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. -
Page 11: Control Of Ancillary Equipment And Interlocks
Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® Control of ancillary equipment and interlocks If the collector is fitted with a Power Box, this can be configured to operate a complete dust collector system and accept inputs from other devices (e.g. PLCs, level probes, explosion relief panel detectors etc.). -
Page 12: Antistatic Earthing
Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® Antistatic earthing If the collector is fitted with an earthing post (see the symbol shown) it is particularly important that the earthing post is properly connected to earth, using the fixings provided, to prevent any static build-up. -
Page 13: Commissioning
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. -
Page 14: Shut-Down Sequence
Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® Shut-down sequence At the end of any period of operation it is most important that all residual deposits are cleared from the PowerCore filter packs. To achieve this, equipment should be shut down in the following order: Stop the main fan, any blower or pneumatic conveying system, leaving the controller and compressed air supply switched on to allow the collector to be... -
Page 15: Operation
Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® OPERATION Principle of operation Filtering operation (fig. 4a) With the collector mounted on the silo or storage container, dust-laden air enters the collector through the aperture at the bottom of the collector. Airflow is directed upwards through the PowerCore filter packs, removing the fine particulate (heavier particulate falls back into the process). -
Page 16: Maintenance
Ensure the pneumatic system is fully isolated and depressurised before any work is carried out. For ancillary equipment not manufactured by Donaldson, refer to manufacturer’s instructions. If it is unavoidable to work on the equipment while a potentially explosive atmosphere is present, care should be taken to avoid introducing ignition sources not present during expected operation. -
Page 17: Servicing Schedule
Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® Filter pack resistance can be checked by connecting a U-tube manometer or differential-type pressure gauge to tapping points on the collector body (see figure 5). This will give a continuous indication of the state of the filter packs. (On the IPC (DR) Controller, filter resistance is shown on the LED;... -

Make a note of the distance from either impeller back plate to fan case (preferred) or inlet eye to impeller front plate, as this will assist with replacement. If required, refer to Donaldson for exact dimensions. 2. From front of fan assembly (non motor end) remove impeller inlet eye from fan casing by removing outer circle of bolts and pulling away the plate. - Page 22 Installation, Operation and Maintenance manual PowerCore Dust Collectors - Series CPV ® 11.
