METAL WASHABLE AIR GREASE FILTERS

Lightweight, metal mesh filters for cooking exhaust systems

Honeycomb Grease Filter for Cooking Exhaust Systems

The Honeycomb grease filter is a lightweight, washable, acid resistant aluminium panel filter designed for use in cooking exhaust systems.

 Construction

Honeycomb grease filters are made from high quality acid resistant aluminium throughout. The filter media is made from 50mm wide aluminium foil, which is specially corrugated into a herringbone shaped channel. This foil when placed one on top of the other will form a curved honeycomb channel.

When the incoming grease laden air passes through this media, the air changes direction. The resultant change in inertia causes the grease to cling and condense onto the aluminium surface. This prevents the majority of the grease form entering the exhaust system. This honeycomb media is encased in a 50mm thick aluminium extruded frame, which is screwed together.

All frames have drain holes for the cooking fat to drain in to the canopy channels. All filters are fitted with steel plated retractable handles. Large D handles, which are fitted offset, are also available on request at extra cost. Honeycomb filters are fully washable panel filter units. They provide extremely low resistance to air flow and ease of cleaning.

 Installation

Honeycomb grease filters must always be installed with its face at not more than 30° from the vertical to minimize the possibility of grease dripping off the filter face. It is important to ensure that the filter is installed with the cell layer vertical i.e. with the handles on the vertical side of the filter. Under no circumstances must the filter be installed with the layer going horizontally.

 Maintenance / Service

Honeycomb grease filters must be cleaned regularly to minimize the possibility of collected grease dropping back in the semi — liquid form of the cell. Cleaners containing caustic solution must not be used as they will corrode the aluminium form which the unit is made.

Mist Eliminator Moisture / Oil Separator

Airepure® model A-6ME Moisture Separators are highly effective in significantly reducing oil mist, water mist, fog or droplets from outside air or recirculated air. In addition, they are useful downstream of DX or chilled water coils and steam or mist-type humidifiers which allows saturated air to condense out. Also used in turbine intakes and as a spark arrestance etc. A-6ME Moisture Separators are designed for a minimum efficiency of 98% on 20 microns water or oil droplets when operating at 2.54 m/sec face velocity

 Construction

A-6ME’s are constructed of a 1.5mm galvanised steel frame (standard); 1.2mm type 304 stainless steel optional. There are drain holes equally spaced on all four sides. Dimples are available on request. 25mm, 50mm, 75mm, 100mm, or any size or thickness can be made. Frames have welded construction; all seams on the air exit side. Bail handles are available to make front load applications easier. Gaskets are available. The media pack in a 50mm filter is 16 layers of expanded metal, knitted mesh (to allow the fluid to drain easily), and corrugated wire screen. Galvanised material is standard. Type 304 stainless steel is optional. 100mm Frame with 50mm media pack also available.

Performance The mist eliminator is designed to operate at a face velocity of 2.54 m/sec. The velocity should not exceed 2.80 m/sec

 Installation

The Airepure® A-6ME mist eliminator must be vertically installed in order to operate at peak efficiency. Mounting hardware must be designed to support the mist eliminator with adequate drainage.
