Build a bag
specification.
Two media are stocked and priced online — polypropylene needlefelt and nylon monofilament mesh, sizes 1 to 4. Everything else is made to order. Work through the choices below, give us a quantity, and we quote it.
1 — Bag size
Sizes 1 to 4 are the standard bags and the ones our housings take. Size 5 and anything outside the chart is made to order.
2 — Media
The fluid, the temperature and whether you want depth or a hard cut point decide this. Two are stocked; the rest are made to order.
3 — Micron rating
Start at the coarsest rating that does the job. Finer than you need means shorter runs and more change-outs.
4 — Collar
How the bag seats. Plastic where no metal may touch the product, steel for hot or aggressive duty.
5 — Handles
Handles let an operator lift a heavy wet bag straight out without reaching into the basket.
6 — Seam
Welded felt has no needle holes for solids to pass through. Woven mesh is sewn and bound.
7 — Surface finish
Felt only. Singed is standard; glazed releases cake more easily and sheds less fibre.
8 — Special requirements
Pick any that apply. Each one may change the media, the lead time or both.
9 — Quantity
How many bags in this order. Type any number, or use a button. Tell us your annual usage in the form as well — a forecast prices better than a one-off.
We do not price made-to-order bags on the website. You get a firm figure, a lead time and a freight cost by return, and nothing is charged until you approve it.
What the specification code means
Every bag we quote carries a code that describes it in full. Quote it back and there is no ambiguity about what you are reordering.
| Segment | Meaning | Example |
|---|---|---|
| MFB | Misonics filter bag | MFB |
| Size | S1 to S4, S5 to order, SX non-standard | S2 |
| Media | PP polypropylene felt · PE polyester felt · NM nylon mesh · PEM polyester mesh · PPM polypropylene mesh · PTM PTFE membrane · HEF high efficiency · CRB carbon · OIL oil absorbent · LCH leachate | PP |
| Micron | The rating in microns | 25 |
| Build | Collar (P, S, S6, G, F, D), then H if handles are fitted, then the finish letter if it is not singed | P |
So MFB-S2-PP-25-P is a size 2 polypropylene needlefelt bag, 25 micron, polypropylene snap ring, no handles, singed. That one is in stock. MFB-S2-PTM-10-S6H is a PTFE membrane bag on a 316 stainless ring with handles — made to order.
Send the specification
Everything you picked above is attached to this form automatically — size, media, micron, collar, handles, seam, finish, special requirements and quantity. You get a reference number on screen as soon as it sends.
What we need to price it
Quantity is the biggest lever on the price, so give us a realistic annual figure if there is one. For made-to-order media, the liquid, the temperature and the pH decide whether the media you picked is the right one — tell us and we will say so if it is not.
