THE RIGHT FILTER AT EVERY STAGE OF THE AIR STREAM
AIR FILTER RANGES
From washable pre-filters on a fan coil to scan-tested ULPA filters over a semiconductor line and multi-stage intake systems on a gas turbine. We select media, efficiency class, frame and housing for your air flow, dust load, temperature and cleanliness target.
01G3 – M5 · EN 779 / ISO Coarse
Panel and box pre-filters with synthetic, non-woven or compressed felt media, cardboard-frame pleated filters and washable nylon mesh filters. The first line of defence for AHUs, fan coils and intake louvres.

02G3 – F9 · synthetic, meltblown & fibreglass
Multi-pocket filters with welded or stitched pockets that inflate evenly for high dust holding and low pressure drop. Includes reverse-flow coalescing pockets for gas turbine intakes and pocket cubes for paint booths.

03M6 – F9 · deep pleat, mini-pleat & V-bank
Rigid fine filters with glass-fibre media in deep-pleat, hot-melt mini-pleat and V-bank formats. A very high media area gives long life, low energy use and moisture resistance, ideal as final filters in comfort and process HVAC.

Request Datasheet →HOW STAGED FILTRATION WORKS
Coarse → Fine → Absolute
Pre-filters catch large dust and insects so that fine filters last longer. Fine filters remove PM10 and PM2.5 to protect coils, fans and occupants. HEPA or ULPA filters at the end of the line capture sub-micron particles and microbes for clean rooms and critical areas. Getting the staging right lowers pressure drop, saves fan energy and extends the life of the most expensive filters.

QUICK SELECTION GUIDE
| Grade | Standard & Approx. ISO 16890 | What It Captures | Typical Filter Types | Typical Use |
|---|---|---|---|---|
| G3 – G4 | EN 779 · ISO Coarse | Coarse dust, insects, fibres (>10 µm) | Panel, mesh, pleated pre-filters, rolls | Pre-filter for AHUs, FCUs, intakes |
| M5 – M6 | EN 779 · ePM10 50–70% | Pollen, fine dust, PM10 | Pocket, pleated panel filters | Comfort HVAC, second stage |
| F7 – F9 | EN 779 · ePM1 50–90% | PM2.5, PM1, bacteria carriers | Pocket, ASHRAE deep / mini-pleat, V-bank | Final filter in offices, hospitals, food |
| E10 – E12 | EN 1822 · 85% – 99.5% @ MPPS | Sub-micron particles | EPA deep / mini-pleat, V-bank | Pre-HEPA, gas turbines, process air |
| H13 – H14 | EN 1822 · 99.95% – 99.995% @ MPPS | Bacteria, viruses on particles, 0.3 µm | HEPA mini-pleat, gel seal, terminal modules | Clean rooms, OTs, pharma, labs |
| U15 – U16 | EN 1822 · ≥ 99.9995% @ MPPS | Ultra-fine particles | ULPA micro-glass or PTFE membrane | Semiconductor, ISO 3 – 4 areas |
EN 779 grades are shown because they are still widely used on drawings; ISO 16890 equivalents are approximate. MPPS = most penetrating particle size. Final selection depends on air flow, dust load, temperature, humidity and the required cleanliness class.
