The unit consists of two fans, each paired with a ceramic heat exchanger.
The two fans provide balanced continuous ventilation without the need for duct-work and are installed directly next to an opening. The fans flow in opposite directions, and reverse every 70 seconds. The regenerative core is charged when exhausting, and discharged in the supply cycle. The air in the supply cycle absorbs the stored heat on its way in and this results in average 85.8% tested efficiency.
This includes the operating noise of the fan, particularly for residents who value comfort. This is a real strength of the fgo. State of the art EC motors and a sophisticated noise insulation system ensure outstanding noise levels: 26 dB at 3.5 m3/h, 32 dB at 5 m³/h and 36 dB at 15 m³/h
As a result of the high heat recovery efficiency of over 90 % the fgo saves energy and cuts heating costs. Just what heat recovery efficiency of 90% means can be seen in a simply calculation: When outside air temperature is – 10 °C and room temperature is 20 °C, the temperature of fresh air heated in the fgo fan is 17 °C.
Hazardous substances in the air are reduced via the integrated G3 or pollen filter.
The window fan fgo operates according to the principle of regenerative heat exchange. A complete unit consists of two system parts. One oscillating axial motor and one ceramic heat exchanger respectively are applied per system part. By means of the oscillating air flow, the ceramic collects thermal energy from the extracted room air and passes it on to the outside air supplied. Both system parts of a unit operate on a push-pull basis so that the fgo fan simultaneously generates a flow of supply air and of exhaust air – at an efficiency level as yet unachieved for this design size of more than 90 %. The cycle of reverse flow rate is preset at exactly 50 seconds and operates continuously and constantly at every flow rate.
The remote ventilation system fgo is a home ventilation system with heat recovery which is integrated in a window profile. This means it is a ventilation system which is slender in every sense of the word and which you visibly hardly notice. 2 complete heat exchanger motor units are incorporated in the dimensions of 86 x 92 x 1050 mm.
The complete fgo fan fits into an adapter profile of a window or door. Horizontal or vertical installation is possible.
