Knitted Panel Filters - Lightweight & Excellent Grease Filtration

A knitted panel filter, also known as a grease filter or air filter, is a framed filter element for grease/dust separation. Compared to traditional woven mesh layers, inner filtration material is multi-layers of metal knitted mesh, which is complex and irregular to make sure apertures are uniformly and precisely distributed for better air-borne grease and dust capturing and max filtration effect up to 98%.

Normally it is used as pre-filtration of inlet systems for air conditioning, heating or cooling system, air washers, compressors, and turbines to prevent small dust and particles from entering. It is also the best suited for grease separation for industrial kitchens whilst maximizing air intake into your cooker hood.


  • Large grease/oil capture capacity
  • Inner metal material with high strength
  • High-temperature resistance, acid & alkali resistance
  • Durable and washable for longer service life
  • The inner pad also can be replaced easily
  • Different material, density, and size choices to meet different needs
  • Available with handles or fold upon request

Different type choices:

Panel filters are normally constructed with three parts: outer metal frame, inner filtration core, and support mesh. Besides knitted mesh, we can also use rhombus foil mesh folded inside as filtration core, which is widely used for coarse air filtration and EMI shielding.

To suit different demands, we can also supply corrugated woven mesh core and polyester /synthetic fiber core as below pictures.
