This process ensures that the separators clean themselves automatically, a benefit that traditional filters do not offer. The grease flows down on the surfaces of the polished fins into a collecting channel. The exhaust air duct is kept dry and free from grease, which helps to improve structural fire protection. The separators are flame arresting in accordance with DIN 18869-5.
Since lately, they are fitted with energy-saving fans in compliance with the Ecodesign directive*, which stipulates minimum efficiency rates for energy-related products sold in the EU from 2013 on. According to REVEN, the new fans reduce the energy consumption of the separators by at least 20 per cent.
* The Ecodesign directive introduces minimum efficiencies for energy-related product such as fans.
