Mesh style grease filters with 45mm/20mm thick Aluminium frame and Galvanised Steel mesh.
These filters are designed for use in commercial kitchens and ventilation from food preperation areas where their primary function is to reduce grease carry over from the cooking area. Rated at 1.5m/sec where the pressure drop is 15Pa for 45mm filters and less than 10Pa for 20mm filters.
Construction involves rolling an Aluminium frame which holds a series of expanded and corrugated Galvanised Steel layers. These layers create an impingement barrier which catches grease from the extract air.
