DTP series low noise ventilation and fume outputting (double usage) fan
briefing
　　DTP series low noise ventilation and fume outputting (double usage) fans are double usage fans developed by our company basing on absorbing the advantages of international. They are low noise, high efficiency box type centrifugal fans, with features as heat bearing, excellent performance, compact structure, little vibration, light and easily be installed. They also could reach the fire fighting and fume outputting purpose, are the second generation of fume outputting and fire fighting products for high building. Now, they are widely sold and rewarded in country.
Usage
　　The series products contain type A and type B. They could be installed on ground or hung. Fan s with motor out the fan case is type A, after setting double rate motor, type A fans could exchange air in low rate, fight fire and output fume in high rate. Fan with motor in the case is type B(generally used for ventilation).
　　1. This type fan could output and input air. They suit to the fire fighting ,fume outputting and ventilation of hotels, restaurants, theatres, basements, workshop and office buildings.
　　2. no stick impurity should in the atmosphere， dust and particle contain should less than 150mg/m3。
　　3. Air temperature : after the high temperature bearing test, Type A series box fans could continuously work for more than 40min under 280℃,with this capacity the fan could fight fire and outputting fume.

DBF type low noise variable volume box fan
　　DBF type low noise variable volume box fan and DEF low noise fan are driven by wind power. Compared with homogenous products, they are possess the feathers like large flow volume, low noise, small volume, electricity saving and conveniently be installed. As adopting DF series low noise motor, this type fans are suitable for the ventilation of factory, civil building, education and office building, as well as the for the concatenation pressure addition of air condition assemble. Type DBF and type DEF box fans could be composed into different types by models. Noise muffler box fan or air filter box fan could be made according customers demands.
Features:
　　 The DBF type low noise variable volume box fans we produced adopt advanced DF series low noise dual-suction centrifugal fans, reamed hole air filter , moderated quality filter ,or sub-grate quality filter. Sound absorption (warm keeping) plank is stick inside, vibration attenuation rubber pad is also used. The fans are with the features as low noise, small volume, light, large flow volume, adjustable rate, variable flow volume, easily be regulated ,sound isolation, air filter and conveniently be installed. After set the electric control, the fans could be controlled in long distance. The DBF type low noise variable volume box fans could be used for concatenation pressure addition for ventilation system; or directly used for air exchange fan.???. the gas crossing the fan should be un-erosive, non-stick particle contained natural air. DBF type low noise variable volume box fans are widely used in air condition projects.
