High efficiency filter bags step in when a standard felt bag can’t hit the clarity target. Multi-layer meltblown polypropylene construction captures fine particles at high efficiency while keeping the flow rates and housing compatibility of a standard bag filter. If you’re considering a jump to cartridges for performance reasons, a high-efficiency bag often gets you there at a fraction of the cost per gallon.
Four Series, Four Jobs
| Series | Construction | Micron ratings | Use when |
|---|---|---|---|
| POXL “Extended Life” | Dual-density | 1–100 | You want a longer-life substitute for a standard felt bag — high flow, high dirt-holding |
| POMB “Standard” | Multi-layer meltblown | 0.5–200 | High filtration efficiency is the goal |
| POMA “High Efficiency” | Multi-layer + prefilter layer | 0.5–200 | High efficiency AND heavy particulate loads, especially at small micron ratings |
| POMX “Ultra” | Multi-layer, maximum efficiency | 0.5–50 | Maximum filtration efficiency is required — the tightest bag we build |
Where High Efficiency Bags Win
- Critical clarity: coatings, inks, process chemicals, plating baths
- Retrofit: upgrade filtration without changing housings
- Cartridge replacement: bag-format economics with cartridge-class efficiency
- Extended life: graded construction loads dirt through the depth of the bag, not just the surface
Sizes and Tops
All four series are available in standard sizes 1–4 plus the 4″×24″, 5″×15/21/32″, and 8″×32″ specialty sizes — they fit all industry-standard bag housings. Top options: galvanized, stainless or polypropylene ring, plastic flange with molded-in handles, stainless band, 9″ Cuno ring, or drawstring. Handles and pull tabs available.
