Baffle Grease Filter

The Baffle Grease Filter is used in kitchen canopies to remove grease from the air. It is universally recognised that there is a need to improve hygiene and reduce fire hazards within kitchens, and the baffle filter achieves both using a design of interlocking baffles providing a torturous route for air through the filter. These filters are available in Stainless Steel and Aluminium.

These filters are designed for use in commercial kitchens and ventilation for food preparation areas. It is universally recognised that there is an increasing need to maintain and improve hygiene standards and reduce the fire hazards within kitchens. The Baffle Grease Filter accomplishes both needs through its design of interlocking blades that provide a tortuous route for the passage of air through the filter by creating two rapid 180° air direction changes. The grease molecules having a far greater inertial force than air impact themselves on the vanes.

The Baffle Filter range is available in Aluminium, Stainless Steel and Brushed Stainless Steel. The filters are made from steel channel frames, with safety edges. Each blade overlaps the opposite one to provide a tortuous path for the grease laden air. The grease then drains down the vanes and out through drain holes provided into a collection tray provided in the kitchen canopy. The completed filter is fitted with two fold flat handle as standard.

Available in a range of standard sizes and also produced to almost any practical size. Available in 38mm and 45mm depth only.

It is imperative that this product is regularly cleaned according to use. This may be accomplished by steam cleaning, washing in a dishwasher using conventional detergents and cleaners or by using proprietary degreasants.

Note: Baffle Filters may be used at higher rated capacities whilst retaining their efficiency,
however it should be noted that this will increase the resistance to air flow.
