226 SMOKE AND HEAT EXHAUST VENTILATION SYSTEMS ARMO-J Axial Jet Fans Jet Fans are high temperature resistant fans which direct the toxic gases to exhaust points by means of creating jet flow, thrust and momentum thanks to having long casing. Thereby this keeps emergency exits and escaping routes free of smoke. These devices are mounted via mounting feets in conformity with the structural beams, sprinkler system units and installment units distribution. Technical Descriptions 234
