KSA cyclonic filters are composed of vertical honeycomb sections. Opening only at the top and bottom, they are designed to force the air to swirl inside. The centrifugal effect is impactful, and continuous – a mechanism that traditional baffle filters do not have. Particles are thus pushed against the honeycomb walls, resulting in better performance. KSA filters are 95% efficient on 10 µm particles with a reasonable pressure loss of 120 Pa.
KSA filters are accredited by the UL (Underwriter Laboratories) as flame-resistant and have NSF (National Sanitation Foundation) Hygienic and safe approval. They are fitted on all hoods and ventilated ceilings.
The UV Capture Ray™ technology neutralises the medium and small-sized grease particles as well as the grease vapours. The efficiency on the medium and small grease particles cannot be matched by traditional grease filters. The efficiency of the mechanical filtration upstream of the Capture Ray™ UV lamps improves the neutralisation process. KSA filters are the most efficient mechanical filters from on 5 to 10 µm grease particles with the lowest pressure loss.
