PES, aramid, PPS, P84, fibreglass and PTFE
A filter fabric selection matrix by temperature, gas chemistry, moisture, abrasion and specialist finishes.
Suitable media by gas temperature
- Polyester (PES)≈130 °CCost-effective, strong and versatile
- Antistatic PES≈130 °CCharge dissipation with correct grounding
- Aramid (Nomex type)≈200 °CMechanical and thermal resistance
- PPS≈190 °CResists acids, alkalis and hydrolysis
- P84≈240 °CHigh fibre area and good cake release
- Fibreglass≈250–260 °CHigh temperature resistance
- PTFE / ePTFE membrane≈250–260 °CChemical resistance and surface filtration
Limits are typical; final selection follows chemistry, moisture, dew point and peak temperatures.
Filter fabric selection matrix
Temperatures are typical guidance. Confirm the final choice against the exact datasheet, gas chemistry, moisture, temperature peaks and cleaning method.
- Typical limit
- ≈130 °C
- Strength
- Cost-effective, strong and versatile
- Limit / application
- Hydrolysis with heat and moisture; cement, wood, dry duties
An antistatic finish does not replace explosion protection: for combustible dust, verify Kst, Pmax, minimum ignition energy and grounding separately.
What the selection takes into account
- The exact fabric datasheet: continuous and peak temperature limit
- Gas chemistry: acids, alkalis, hydrolysis and oxidation (O₂ control)
- Moisture and dew point — below it blinding and corrosion begin
- A/C ratio (gas flow divided by cloth area, m/min) and the pulse cleaning regime
- Abrasion, cage condition and cleaning method (gentle cleaning for fibreglass)
- Specialist finishes: antistatic media, PTFE/ePTFE membrane
How to recognise the wrong media
Signs include rapid ageing, shrinkage, hydrolysis, burns, blinding, high residual ΔP, poor cake release or unstable emissions. Analyse the element and the duty history.
With high baghouse ΔP, first check the gauge, compressed air, valves, hopper and dew point: assess the media only after removing the overload and restoring cleaning.
Frequently asked questions
Which files should be attached to an enquiry?
The specification, datasheet, OEM reference, drawing, nameplate and mounting photos, process analysis, duty map and recent ΔP, emissions or filtrate data.
Can the media be changed in an existing system?
Yes — after auditing the housing, fan, hydraulics, controls, site and actual duty. Media, compartments, the pulse system or instrumentation can be replaced.
