The DFRPC 3-12 from Riley Industries is from our NEW range of Industrial Dust Filtration Units. 

The DFRPC 3-12 is a Down Flow Reverse Pulse Cleaning cartridge filter system 

Many industrial applications will produce waste dust streams 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.

Industrial Cartridge Filter design

The DFRPC 3-12 dust extractor can filter highly-contaminated volumes of air in a condensed format. The dust-laden waste gases enter through the inlet by vacuum generated from the fan set. The gases are then filtered through the cartridges and exit through the vents into the clean air plenum at the reatr of the extractor. The clean air is then exhausted outside or re-circulated  back into the immediate area depending on the application in hand.

This model has been fitted with our standard duty Cellulose filters but, they also can be offered in a non-woven material for those applications where non-woven cartridge filters are suitable.

The development of downward airflow and inclined media element configurations has resolved the issue of dust retention on the upper surface of the media. It also enables more compact Industrial 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.

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

The DFRPC advantage can be found in the collector’s design featuring a ledgeless hopper in combination with proprietary Nanoweb filter media and
reverse pulse cleaning technology, the DFRPC offers strong performances in traditional applications such as metal and wood working, which all adds up to long-term savings and improved performance in most applications.

This Model Industrial Cartridge Filter is in stock and available for immediate supply. For special purpose machines or non stocked versions, we offer an exceptional turnaround time and can offer build times in as little as three weeks.

Types of Industrial Cartridge Filters available

The 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 of 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 recognised their potential use for low dust loaded non arduous dust collector applications.

Cartridge Dust Filters
The wider application of Cartridge Dust Filters in the 1990's forced the development of sophisticated technical medias 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.
