Filter Media Rolls
Whalesens produces the filter media as well as the filters made from it. The range covers non-woven polyester pre-filter media, non-woven glass fibre media and carbon-loaded media, supplied in rolls, as pre-cut slices or as framed pads. The rolls are the same material used in our own panel, pocket and bag filters, so a filter maker can buy media and finished filters from one source.
The polyester media runs from G2 to G4 in EN 779 with a progressive density structure; the glass fibre grade is used for paint mist and high dust holding duty; and the carbon media is supplied as WS-AC350G and WS-AC480G. Send us the grade, the cutting width and the roll length, or the frame size if you want the pads cut for you.
Filter Media Rolls range
Selection table
| Model | Filtration grade | Media | Thickness | Initial resistance | Final resistance | Temperature |
|---|---|---|---|---|---|---|
| Activated Carbon Filter Media | G3, G4 | 5 ± 1 mm (G3), 10 ± 1 mm (G4) | 20 Pa | 200 Pa | 180 °C | |
| Fiberglass Filter Media | G3 (EN779), EU3 (EUROVENT) | Non-woven glass fibre, progressive density | 60 mm and 100 mm | 15 Pa and 20 Pa | 250 Pa and 280 Pa | ≤170°C |
| Pre Air Filter Media | G2, G3, G4 (EN779); EU2, EU3, EU4 (EUROVENT) | Non-woven polyester (PET) fibre, progressive density | 5, 10, 15, 20, 25 mm | 20 – 25 Pa | 125 – 250 Pa | ≤ 100 °C |
How it compares
Polyester vs glass fibre media
Polyester media is the general-purpose choice: inexpensive, stable in humid air and available in a wide range of weights and thicknesses. Glass fibre media is denser and holds considerably more dust in the same face area, which is why it is used on paint booth intake, oil mist and heavy pre-filtration duty.
Plain media vs carbon-loaded media
Carbon-loaded media adds odour and gas removal to coarse particle filtration, at the cost of some dust holding capacity and a higher unit price. It is worth using where odour, formaldehyde or solvent vapour is a real complaint; where the problem is only dust, the plain media is the more economical choice.
Roll media vs a finished filter
Buying media lets you control stock, cut to any size and replace only the pad. Buying the finished filter gets you a frame, a gasket and a tested assembly, which is usually cheaper once labour and waste are counted. Many customers do both: rolls for large flat areas, framed filters for the critical stages.
Where it is used
Paint booth intake and ceiling
Roll media laid over the ceiling grid distributes air across the booth and traps overspray, and is replaced as a sheet rather than as a frame.
Paint booth case →Industrial coating and VOC control
Pre-filtration ahead of carbon stages on coating, printing and chemical lines, where dust has to be removed before it blinds the carbon media.
Coating and VOC solutions →Commercial and data centre HVAC
Coarse and medium pre-filters for air handling units, protecting the main filters and the cooling coil.
Data centre HVAC solutions →Food and beverage plants
Intake and process air filtration where the media has to be cleanable, odour free and supplied to a documented grade.
