WAM RECOFIL Dust Conveying System

RECOFIL is an economic, pneumatic dust recovery device which has been specially developed for installation beneath filter hoppers.

WAM Recofil Dust Conveying System

RECOFIL automatically removes dust collected inside the filter hopper conveying it to a storage device. There is no filter stoppage and no need for any manual operation.

This is possible thanks to an innovative, patented system that utilises the air pressure from the filter to convey the dust in dilute phase without any further equipment required.

Thanks to its unique features, the RECOFIL system solves all maintenance and environmental problems.

In combination with the TECU Fume & Dust Filter and the EASYFILL Bulk Bag Filler (see relevant pages), the RECOFIL™ radically reduces maintenance costs versus traditional solutions with a very quick return on investment.

The complete system can manage simultaneously up to four filters.

The programmable POWERFIL control panel makes supervision of the fully automatic operation superfluous.
