Model Description: 1, fan performance properties listed in the table is the most efficient performance within range, according to the air volume is divided into five operating point performance kitchen exhaust fan, according to prevail in the selection of the performance table. Fan factory is qualified products at rated air flow. 2, the wind turbine installation can be divided into horizontal and rooftop jgf exhaust fan, such as when to air flow, total pressure, dimensions and other properties have special requirements, our company will provide you with a separate design and production. 3, HTF-Ⅰ, HTF-Ⅱ represents pressure type fire temperature exhaust fan, leaf type axial flow type: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF -Ⅳ representation pressure fire temperature exhaust 4, HTF-X as a silencer fire temperature exhaust fan, the user can choose according to the actual needs of different species. 5, HTF-W series rooftop fire temperature exhaust fan, the user can choose according to actual needs retardant fiberglass hood or steel hood. 6, HTF-D as a low pressure type fire temperature exhaust fan. 7. Special Note: GYF and HTF series fan is like .S) overview, with the same machine number than the centrifugal fan wind big exhaust fans, air pressure higher than the axial fan, and other characteristics can be axially mounted; low noise, consumption Electric province, efficient wide area, convenient to install and use than the centrifugal fan, reliable operation. Features 1. Compact structure, easy installation, reliable operation; The fan than axial or centrifugal small size in the case of the same amount of wind, air pressure can be directly connected to the duct, horizontal or vertical mounting box exhaust Fans, easy operation features. 2. Low noise: The fan casing is specially designed to greatly reduce the outflow of noise. In the unit amount of wind, air pressure unit operating conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, can obtain higher fan pressure. In the industrial and mining enterprises and senior civil ventilation system can replace the low-pressure centrifugal fan or replaced without the need for a large number of high-pressure axial fan silencer measures. 3. Wide range of applications: This series points single-speed and two-speed two models, according to different occasions, changing the mounting angle of the fan, change the number of leaves and converting speed to its requirements. 6, various types of muffler, bend muffler, silencer duct, plenum chamber muffler blinds. 7, the fire temperature exhaust fan, Francis fan, fire ventilation dual tank centrifugal fans, axial fans, induced fan, ramps flow fan, the wind chassis and other products. 8, energy efficient new wind ventilators, dust purification equipment. 9, the major air conditioning manufacturers supporting a variety of table cold, heaters, humidifiers, air curtain, air curtain, air conditioning flaps and other accessories. 10, at the same time to undertake the entire central air-conditioning design, manufacture, installation, repair, maintenance and technical advice. Companies to strict production control procedures as well as excellent service awaits you, to guide, to discuss cooperation! Features: excellent high temperature performance, high efficiency, easy installation, reliable operation (to produce single-speed, two-speed, frequency and Promise Speed, rooftop exhaust fan fire and explosion Fire-type special fan) and obtain fire product license. Uses: High-rise buildings, oven, tunnels, underground garage and special industrial and mining enterprises and other fire temperature exhaust, exhaust. Specifications: Fan diameter: φ350 ~ φ1500mm air volume: 3350 ~ 93800m3 / h Pressure: 280 ~ 819Pa box exhaust fan, exhaust fan where the good (certified), Liaoyang exhaust fan from Shandong GREAT limited air-conditioning fan company.
