Where this media earns its place
The chemical-resistance choice. Same depth filtration as polyester in a medium that shrugs off alkali, most acids and a far wider range of solvents — at the cost of a lower temperature ceiling.
Alkaline wash solutions, plating and metal finishing, aggressive chemistry, food-contact duty.
Excellent across acid and alkali. The one to use with high-alkaline ultrasonic chemistry.
Up to 90 °C. 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 →What are you filtering?
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.
