GYF fire temperature exhaust axial fans Overview; 1. Purpose: GYF fire temperature exhaust axial fans tested in accordance with GB50045 ~ 95 "fire protection design of tall buildings" and GB50067-97 "garage, repair garage, parking lot design Fire Code "htf exhaust fan, is a new energy-efficient exhaust fan fire. The fan can be used as various buildings dedicated fire smoke, but also for high-rise buildings, general building, underground garage, culverts and other mines of smoke and exhaust temperature exhaust fan fire, as usual underground repository for row air ventilation exhaust fan, turn with winds of smoke when needed. 2. Structure: airfoil axial flow type: There GYF-I (single speed) and GYF-SI (double speed); two kinds of fire exhaust fan. Leaf type with diagonal flow: There GYF-II (single speed) and GYF-S2 (double speed) of two fire exhaust fan. If users have higher requirements on noise, can be made GYF-BX silencer exhaust fan fire. Fans can also be made vertical, mounted on the roof to do with fire smoke. GYF fire temperature exhaust fan consists of five main components: (1) the impeller (2) motor (3) within the circulating air impeller (4) guide vanes, the inner cylinder, guide hole (5) of the outer cylinder. Model: HIF-II (double speed) series fire exhaust fan, high temperature motor, totally enclosed motor built-htf exhaust duct exhaust fan fire, with high specific motor cooling system efficiency, low noise, reasonable structure, Small size, easy installation application: high-rise buildings, drying room, underground garage, or high-temperature exhaust ventilation. Capable of continuous operation at 300 degree heat for 60 minutes or more, the medium temperature conditions of continuous operation at 100 degrees 20 hours / times without damage, fire is the ideal necessary equipment. htf exhaust fan _ Chenyu air conditioning (certified) _ exhaust fan Siping City by Wu Chen Yu Air Conditioning Equipment Co., Ltd.
