This media is not held in stock. Polypropylene needlefelt and nylon monofilament mesh are — those two are priced on the site and ship from stock. Everything else, including this one, is built to your specification and quoted. Build the specification and get a price →

Exact ratings, ring material, surface finish (singed or glazed) and food-contact compliance are confirmed per order against the manufacturer’s current datasheet.

Multi-layer graded-density construction. The layers get progressively finer through the thickness, so coarse solids are caught early and fines deep — giving higher efficiency and roughly double the dirt-holding capacity of a standard felt in the same housing.
Where change frequency is the operating problem, or where a finer rating is needed without shortening runs.
The upgrade path when a standard felt is being changed too often. Same housing, same size — roughly double the area.
Media dependent. The housing seal has its own limit — the lower of the two governs.
Bag price moves with media, micron, ring type and quantity, and drops sharply at volume. Tell us the spec and your annual usage for a per-bag rate and a standing-order price. Get bag pricing →
Pick the size, media, micron, collar, handles, seam and finish. The builder gives you a part code and a full specification, and tells you whether the bag is one we hold or one we quote. Minimum five bags, then any number above that.
Build a custom bag specification →Flow rate, fluid, temperature, particle size and how often you want to change bags. We size the housing and the bag around that and quote the pair, delivered and commissioned.
