This guidance sheet forms part of a series of guidance sheets on preventing and managing offensive odours, and should be read in conjunction with EPA Victoria’s Odour Guidance for Industry webpage.
Constructed using sheets of metal mesh, these filters are ideal for trapping/removing oil and grease from exhausted air. Air passing through the mesh changes direction, causing oils and grease to condense on the metal surface. This removes most of the oil and grease particles from the air before it passes through the exhaust system.
Metal mesh filters are most commonly used in cooking exhausts to remove oils and grease from the air prior to further treatment in an odour control system. They can also be used as a pre-filter for odour control systems to remove larger particles that could clog an exhaust system, or within heating/cooling systems.
Suitable for: oil and grease filtration, other moisture removal, heating and cooling systems, pre-filtering.
Industries that would use this: many businesses or sites could benefit from the implementation of a metal mesh filter, such as those with big coolers, the food and beverage industry, industrial machine shops, and mechanics. It should be noted that metal mesh filters can be advantageous to even the smallest sites for their heating and cooling.
Metal mesh filters are constructed by layering several sheets of metal mesh on top of one another to create miniature air tunnels that force the air to change direction. This results in airborne oil/grease particles sticking to the filter and condensing, removing it from the air, allowing the air to move through to other odour treatments without risk of damaging the equipment, or be dispersed outside.
