Plasma Clean Coil Type Hood Filters are designed to capture oil and grease in commercial kitchen extraction canopies. The unique design of the filters enable them to capture up to 95% of grease particles, in comparison to 20 – 40% grease capture using the more traditional baffle-type filters. By preventing grease and oil particles entering into the ductwork using a high efficiency primary grease filter, the number of ductwork cleans is significantly reduced along with downstream equipment maintenance.

Completed combustability test for materials in accordance with AS1530.1-1994.  See report attached.


The purpose of the Coil Filter is to stop oil and grease from entering into the extraction system. There are four stages to the operation:

  • Stage 1 – oil vapours condense on the large surface area of the filter coils as heat is transferred from the air.
  • Stage 2 – the air is spun into a vortex and the droplets of oil and grease continue in a straight line.
  • Stage 3 – the oil and grease particles then collide with the filter coils, and the oil-coated filter surface traps more oil and grease due to its enhanced viscosity.
  • Stage 4 – the oil and grease droplets simply settle due to gravity and are collected for recycling.


Installation is simple, if you are producing a new canopy, let us know and we can advise on the design and dimensions of the Coil Filter mounting plate. If you have an existing canopy, then an adaptor plate is available to enable the Coil Filters to be installed into existing kitchen canopies, replacing existing low efficiency baffle type filters.


Oil and grease arrested by the unit is collected in the filter cup at the front of the unit, and can be recycled along with the spent oil from the frying range. The stainless steel filter can then be washed in warm soapy water or in the dishwasher. Depending on the level of cooking, the system can be washed daily or as part of a weekly cleaning routine. Remember that the oil trapped by the Coil Filter would otherwise have found its way into the ductwork, requiring routine duct cleaning.
