G2 to M5 cassette filters for coarse and pre-filtration
Panel (cassette) filters capture coarse dust and debris before it reaches more expensive filter stages and equipment. They are used in air handling units, ventilation ducts, compressors and purpose-built housings.
We supply flat, pleated, polyurethane and metal-mesh versions, with cardboard, galvanised or aluminium frames.
Key features
- Low resistance to airflow
- Protects downstream high-efficiency and HEPA filters
- Disposable or washable versions
- Metal-mesh options for grease, sparks and oil mist
- Suitable for corrosive environments
