AF-200 Automatic hydraulic filters

These automatic hydraulic filters, combine the advantages of high quality filtration from different water sources (sewage, reservoirs, rivers, lakes, etc.) with a self-cleaning feature, offering the customer a continuous water supply.
The filters are designed for use in a wide range of industrial, municipal and irrigation applications.
The main element is made of stainless steel with a large filtration open area for water flow in order to withstand high dirt load and pressure. Cleaning of the screen is performed once the pressure loss (ΔP) across the filter has reached the preset value [up to 0.5 bar (7psi)].

The flushing valve opens and pressure is released from the hydraulic piston, water flows outside through the flushing valve. Pressure in the hydraulic motor chamber and the dirt collector is significantly lowered and the dirt collector nozzles movement and rotation cleans the whole screen internal surface. The flushing cycle takes 5 seconds. The flushing valve closes at the end of the cycle and the filter is clean.
During the whole process water supply is uninterrupted.

• Inlet/outlet on an axis of 90°.
• Filter housing material of construction: Carbon steel.
• The filters are electrostatically coated with polyester or epoxy powder at a thickness of 150-200 µm (micron meters) and oven cured.
• Filters are supplied with a stainless steel screen, available in varying micron size as needed: 50-3000 µm (micron meters).
• Inlet/outlet can be either:
  1. Quick coupling connectors (allowing flexibility and easy assembly)
  2. Flanged
  3. Female threaded [up to 4"/100 mm diameter]
