The Cyklotec cyclone filter consists of a filter housing with damper, pressure tap and a number of filter cassettes. Each cassette contains ten cyclones (spiral formed cylinders).
The Cyklotec has uniquely effective grease separation even at variable air flow rates. The effective filtering minimizes the risk of fire and reduces maintenance of the duct system. The filter's design prevents clogging which always guarantees the correct exhaust air flow.
Since each filter cassette functions within a broad flow rate range, kitchens' needs are normally met using a small number of cassettes. The cassettes are easily removed and cleaned in the dishwashing machine.
A filter cassette consists of ten cyclones. The cassettes are easily removed for cleaning in the dishwashing machine.
The exhaust air rate in the cyclone determines how effectively the separation of particles occurs. Higher speeds make for more effective separation but also a larger pressure drop. In the range of 20-90 Pa, the cyclone filter works effectively at a low noise level. The Cyklotec separates all particles larger than 7 µm at the recommended flow and 9 µm at 50% rate. For this reason the Cyklotec can be used in kitchens where the fan is used at both full and 50% rates and retain adequate particle separation.
The Cyklotec's filter cylinder has a unique spiral design that creates an accelerated air flow rate. The aerodynamic design provides much higher air speeds even at low air flow rates. This is the secret behind the Cyklotec's superior performance
Filter housing in brushed stainless steel sheet metal. Sleeve coupling connections with damper. Pressure tap. Filter cassette in stainless steel sheet metal. Filter cassettes can be replaced with a piece of blank sheet metal.
The number of filter cassettes in the Cyklotec cyclone filter is determined by the exhaust air flow. A pressure drop of at least 20 Pa through the filter is recommended for efficient separation. This corresponds to the lower exhaust air flows in the table below. At the higher air flows, the pressure drop is 80-90 Pa.
|60 - 150||1||250||295|
|120 - 250||2||315||400|
|170 - 340||3||400||620|
|215 - 430||4||400||840|
|250 - 520||5||400||1060|
Reported dB(A) values apply at 10 m2 Sabine, which corresponds to an attenuation of 4 dB.
The sound power level Lw (dB), divided into octave bands, is obtained by adding the following correction Kw to the noise level in question. Lw = LA + Kw (dB).

The efficiency of the filter has been measured by a certified test institute according to standard VDI 2052. The diagram shows the filter's particle separation at the recommended (80 Pa) and 50% air flow (20 Pa). Note that even at 50% flow rate all particles > 9 µm are separated.
Reported sound attenuation ΔL (dB) regards the total sound reduction between the duct and room including end reflection.
