Multicyclone grease filter
The special design of the NOVA filter causes two-sided air intake, introducing it into a symmetrical swirling motion characteristic of cyclone filtration. Centrifugal force separates heavier grease particles from the air, which are then directed by gravity to drains located at the bottom of the filter.
NOVA filters are equipped with an easily removable second stage of filtration in the form of an additional progressive mesh filter. Purified air can be directed straight to heat recovery in heat exchangers located in the ventilation units, generating significant operating savings for the entire catering facility.
Main features
- Very high filtration efficiency
- Removable Second Filtration Stage
- Both filtration stages can be washed together or separately.
- Filters mounted at an angle – preventing grease build-up inside the filter
Very high filtration efficiency
Total filtration efficiency is at least 99% for particles of 6 µm, 87% for particles of 4 µm, and 73% for particles of 3 µm, with constant air flow resistance at a maximum of 120 Pa. Efficiency confirmed by tests conducted by the independent laboratory DMT GmbH & Co. KG in Essen, based on the VDI 2052–1:1999-09 standard. Filters are mounted at an angle to direct separated grease particles away, preventing grease accumulation inside the filter. Filters are suitable for washing in commercial dishwashers.
Removable Second Filtration Stage
The second filtration stage, in the form of a progressive mesh filter, is mounted directly on the cylindrical multicyclone filter to limit the dirty surface area and minimize the amount of grease entering the exhaust chambers of hoods in cases where the second filtration stage is installed directly under the hood’s exhaust spigot.
Both filtration stages can be washed together or separately.
Both the cylindrical multicyclone filter and the second stage progressive mesh filter are made entirely of AISI 304 stainless steel and are suitable for washing in commercial dishwashers. The filters can be washed together or separately.
Filters mounted at an angle – preventing grease build-up inside the filter
The filter assembly uses gravity drainage of separated grease from vapors outside the filter to tanks installed under the exhaust chambers of hoods. This solution increases hygiene levels and reduces fire risk compared to other types of filters that accumulate grease directly inside after it has been separated from vapors.
