While many pressure leafs use stainless screens, NFM also provides many synthetic filter cloth covers for the pressure leafs in many styles and shapes.

NFM reworks a wide variety of sizes and shapes of pressure filter leafs. When finished these reworked leafs are better quality than the OEM leafs.

These Filter Leaves have been damaged by over pressurizing and Bridging. When the frames bridge the pressure pushing downward towards the outlet will bend and tear the filter leaf. The damage will vary from bending to ripping the center or nozzle out of the leaf.

All NFM rescreen and rebuilds are completely disassembled and each component is inspected.
If a component is no longer usable were the center member is damaged beyond repair the customer will be notified and a quote for the additional cost to replace will be sent.
After evaluation each reusable component is cleaned and reconditioned to like new condition.
This process is the step that separates us from our competition.
Our competition will simply install new filter media over the worn and damaged filter frame.

After all components have been reconditioned they are reassembled an the same order as a new fabrication.
This insures the filter leaf will be in like new condition when completed.
Our standards on weld procedure, spacing, and assembly procedures exceed the OEM and all of our competition.
On USF Leaves our weld spacing will not exceed 4” and the welds will be directly in line with the weld across in all directions to insure taunt and strong center member, the OEM will have spacing as much as 16” and the welds will be random.
The assembly procedure is the same as new fabrications and the filter media is formed to each leaf and not to a jig. Our assembly procedure insures the filter media will be taunt and perform at optimal clarity and flow.

Continuous Spot Weld

The NFM continuous spot weld is an alternative to laser weld frames offered by USF.
The filter media is pulled taunt with our tensioning device which keeps the screen flat and tight during the spot welding procedure. This provides a filter screen that will last longer and provides a leak free seal by not allowing the filter media to bunch up during the spot welding operation.
