What Is an HWS Oil Mist Filter?
The HWS series is a specialised oil mist and salt mist eliminator built for demanding industrial and coastal environments. It captures airborne oil aerosols from machine shops and kitchens, and salt-laden mist in seaside or offshore installations, protecting downstream equipment and improving workplace air quality.
Construction & Materials
- Frame: 304 / 316L stainless steel or aluminium—corrosion resistant and structurally rigid.
- Media: 304 / 316 gas–liquid mesh (demister pad) with high dust-holding capacity and a long service life.
- Metal media is flame-retardant, lowering fire risk compared with synthetic pads.
- Cleanable and reusable: the pad can be blown clean and returned to service repeatedly for permanent use.
Standards & Customisation
The HWS range is designed to comply with EN779:2012. Non-standard sizes are accepted on request, including made-to-drawing configurations.

Where to Use It
- Large commercial and industrial kitchens.
- Large machine-tool processing plants and metalworking workshops.
- Hardware-parts foundries and casting houses where oil mist is generated.
- Coastal or high-salt-mist sites as a pre-filter for outdoor air intakes.
Frequently Asked Questions
What does the HWS filter remove?
It captures airborne oil aerosols from machine shops and kitchens and salt-laden mist in seaside or offshore installations, protecting downstream equipment and air quality.
What materials is it built from?
Frames are 304 or 316L stainless steel or aluminium, and the media is a 304 or 316 gas-liquid mesh demister pad with high dust-holding capacity.
Is the media reusable?
Yes. The metal demister pad is cleanable and reusable, and being flame-retardant it lowers fire risk compared with synthetic pads.
Where is it typically installed?
Machining centers, commercial kitchens, coastal and offshore plants, and any site where oil or salt mist must be stripped from the airstream.
