HTFC-DT Series Fire common dual low noise cabinet centrifugal fan (in the Department of fire exhaust fan) Overview, HTFC series of fire (ventilation) dual low noise cabinet centrifugal fan is a high efficiency, low noise centrifugal fan, with high-temperature, high-performance compact novel structure, small vibration, light weight, ease of use, hotels, restaurants, halls, theaters, basements, industrial enterprises, offices and other places ideal for smoke ventilation, high-rise building fire exhaust fan replacements. Multi-blade impeller is forward curved blades, with high efficiency, low noise, large air volume, stable, stable quality, durability and other characteristics. Volute using high-quality galvanized sheet, mechanical mold production. 4, HTFC series of fire (ventilation) Low noise mode dual centrifugal fan is divided into A and B two types, Dang pressure blower, A motor mounted outside the box for fire smoke; B Motor mounted in the housing, for ventilation. We offer Hefei fire temperature exhaust fan price for your news and information, company's strict production program and excellent service awaits you, to guide, to discuss cooperation! Differences and centrifugal fan air flow and the shaft is parallel The called axial fans, Chaohu swf pressure blower (such as firefighting exhaust fan) contrary is a centrifugal fan, (such as fan coil fan). The fundamental difference between axial fans and centrifugal fan cabinet in mechanical fan structure: axial fan blade diameter limited to the housing diameter, swf Francis pressure blower and centrifugal fan, there is no limitation in this regard, you can use the blade forward or backward blades for wind pressure requirements to adapt to more wide. And do silencer inside handle on the noise performance has obvious advantages. Due to the general low number of revolutions of the motor, the motor power, with a lot more power. If ventilation systems usually used, as far as possible tank centrifugal fan, fire smoke is not commonly used systems, high temperature axial fan more economical! Centrifugal fan axial fans in the combined ratio to select the amount of wind and big pressure on the more advantages (mainly on fan efficiency and noise performance)! Centrifugal fans and axial fans difference is: 1, changed the flow of centrifugal fan duct inside the medium, Lu'an low noise Francis pressure blower, and axial fan does not change the flow of the medium within the duct; 2, the former air volume and pressure are Large, air volume and pressure which are very low; 3, the former is more complex installation, which is relatively simple to install; 4, the former motor and fan are generally connected by a shaft, which is generally in the fan motor; 5, the former often install In the air conditioning unit inlet and outlet of the boiler drum, induced draft fan, and so on, which is often installed in the duct which, or the front end of the duct outlet. 4, high efficiency: This series of fans using advanced CAD software by the multi-objective optimization design of new products developed by the test shows that fan efficiency greater than 80%, some big machine number greater than 85%, and has a flat efficiency curve characteristics, so conducive to energy conservation. 5, easy installation, covering less than the centrifugal fan: Del fan base in the form of oblique axial fan or fans, can be connected directly to pipe or wall installation with air, it may take the form of horizontal or vertical installation, to a large extent saving footprint.
