Down Flow Reverse Pulse Cleaning (DFRPC) Range

Having been in the surface finishing industry as a supplier of quality used plant and equipment for over 50 years, we have seen the full spectrum of machines on offer from all of the major suppliers all over Europe. Having seen the best available, we now have a design that incorporates features that we believe will rival any of the current extractors available on the market today and at a very competitive price. 

Many industrial applications will produce dust which needs to be extracted and filtered accordingly. All of our dust extraction systems are made in the UK and can be tailored to meet your specific needs.

The DFRPC delivers optimum performance and is one of the best value dust collectors available in today’s marketplace. 


  • Built in the United Kingdom using only the best components available.
  • Made from fabricated and welded heavy duty 4 mm carbon steel.
  • Unit mounted and free standing fan sets tailored to make the best use of the available space.
  • Ledge less construction and angled filters eliminates dust build up.
  • Compact design minimises floor space.
  • Powerful performance filter cartridge technology.
  • Cleaning system that provides 30% more cleaning energy.
  • Cost savings from fewer filter changes, reduced filter disposal costs, and less energy usage.
  • Easy system set up.
  • Easy for maintenance.
  • Inlet shrouds to prevent direct impingement onto the top tier of the elements.
  • Dust containers dust discharge.
  • ATEX rated explosion panel included.
  • Supplied with 80/20 Cellulose cartridges.

Modular Construction

The three module high design has a large range of capacities that can be achieved by simply coupling together any combination of extraction units together with common inlet and outlet manifolds offering not only a wide range of capacities but also dutied systems with independent fans for multi-point extraction systems.

The advantage of sharing a common design, allows any installed system to be expanded at any time as and when it may be required.

Industrial Cartridge Filter Design

Our dust extractors can filter highly contaminated volumes of air. The dust-laden waste gases enter through the inlet by vacuum or pressure. The gases are then filtered through the cartridges and exit through the vents into the clean air to be either channelled outside or re-circulated depending on the application in hand. Our dust extraction filters are easily changed from the front of the unit, and they can also be offered in a non-woven material for those applications where non-woven cartridge filters are suitable.

The use of downward airflow and inclined filters has resolved the problem of dust retention on the upper surface of the filters. It also enables a more compact cartridge filter design and enhanced cleaning efficiency as every element is cleaned by its own pulse valve instead of rows of elements cleaned by a jet pipe arrangement.

A ledge less hopper in combination with proprietary Nanofibre filter media and reverse pulse cleaning technology offers strong performances in traditional applications such as metal and woodworking, which all adds up to long-term savings and improved performance in most applications.

Industrial Cartridge Filters 

Riley's DFRPC dust extractors have an extensive range of cartridge filters available to suit most applications. These dust extractor cartridge filters are technically advanced in design to give you the cleanest returned air. The cartridges being cleaned by compressed air makes the system highly efficient. Cartridge filters can save up to 40% on space in comparison to conventional multi-pocket or tubular bag type extraction systems.

Pleated Cartridge Filter
Pleated Cartridge Filter elements were originally designed and developed for use as truck air intake filters. The media was very simple folded and pleated paper and they served that purpose very well. In the mid 1980's the dust control industry recognized their potential use for low dust loaded non arduous dust collector applications.

Cartridge Dust Filters
The wider application of Cartridge Dust Filters in the 1990s forced the development of sophisticated technical media to allow the design to be applied to a much wider range of duties. These units are now developed to a point where they offer a very low cost solution to a very wide range of dust control applications.
