Automatic Self-Cleaning Filter - AutoFilt® RF3

Supplier: HYDAC International

The AutoFilt® RF3 is an automatic self-cleaning filtration system designed for continuous maintenance-free filtration for all major manufacturing and processing industries.


 It removes solid contamination from low viscosity fluids such as water and  machine tool coolants. Its rugged construction and self-cleaning feature provide companies with increased machinery reliability resulting in reduced operating, labor and maintenance costs.

Superior removal of contamination particles from water is accomplished with Slotted Tube / Wedge Wire Filter Elements ranging from 50 to 3,000 microns and SuperMeshTM Filter Elements with 25 and 40 microns.

The automatic self-cleaning process begins, as soon as, the filter elements become contaminated. Due to the unique single element cleaning process, the total filtered flow is not reduced during the cleaning process. Flow rates range can range from 20-31,000 GPM and housings are available with ANSI mounting port flanges from 2" to 36".

HYDAC can supply numerous combinations of housing materials, as well as, system operating equipment to reach the optimum installation for every industry application.

Cost Effectiveness
Particle contamination in water accelerates the rate of wear on system components such as spray nozzles, water valves, and pipelines. This could result in
premature component failure. The use of automatic self-cleaning filters lead to a significant decrease in service and maintenance intervals resulting in time and labor savings. As well, costs for replacement equipment and waste disposal can be minimized.

Process water is typically contaminated with solids and water companies apply surcharges to handle the contaminant discharge. The HYDAC AutoFilt® RF3 is ideally suited for removing these contaminants prior to discharge thus reducing or eliminating any financial surcharge.
