Elfi Filters

The flagship product of the ELFI Filter range is their self cleaning back flushing filter, this unique design uses differential pressure to achieve self cleaning and most importantly, does not take the filter out of service during the cleaning cycle. The ability to completely self clean whilst remaining in service, removes the need for costly replacement filter cartridges and with no downtime, the return on investment for such a system can be measured in a few months, if not weeks.

All units supplied by ELFI can be manufactured in AISI 316 stainless steel, Duplex stainless steel or Super Duplex stainless steel, the filter supporting mesh can be either plastic or stainless steel depending on the application and all units can be for standard or high temperature applications.

Manufactured at their ISO 9001 accredited factory in Parma, Italy, ELFI Filter products are exclusively distributed in the UK & Ireland by Wycombe Water Limited, contact us directly to discuss with our technical experts your applications and requirements.
