Horizon Air Conditioning Equipment | [manufacturers] duct fans | fan duct is provided by Horizon Air conditioning equipment. We are a Texas Air Conditioning Equipment Co., Ltd. Hongxin (www.hxktsb.com) located at: Shandong Dezhou specializes in: New air unit fresh air ventilator fan air pressure delivery outlet damper chassis outlet name:... ISQ (pipeline centrifugal fan) ● Use: supply and exhaust pipes, supply and exhaust filtration, mute wind chassis, explosion-proof ventilation, fire smoke, etc. ● Air flow range: 600 ~ 49,000 m3 / h ● Static pressure range: 100 to 1 duct fans, 600Pa ● AMCA certified sound and air performance after three generations of dumping ● Xiang Xin centrifugal impeller, the efficiency of high-performance pipeline fan, low noise impeller balancing ● Level G2.5 (ISO1940) ● Square without scroll structure, small size, light weight, easy installation ● Precision entrance venturi to reduce turbulence, noise reduction ● National Fire certification Texas has air-conditioning plant Hongxin graph can understand the fan according to the performance parameters, the vertical axis represents the fan static pressure (pa), the horizontal axis represents the fan Airflow (m3 / h), when the operating conditions for the (vertical axis) corresponding static pressure (abscissa) can be read out air volume. For example: 20 m pipe pressure loss is about 150pa, then you can read the actual operation of the air volume of the fan. Performance curve can be sized according to the diameter of the original pipe-laying, but the main channel is large enough to ensure high-quality pipe fan of allowing smaller pipes, duct is too small will affect the fan performance. According to the area of ??space can also multiply the height calculated volume of space, room, office ventilation is 2-3 times per hour, bathroom ventilation frequency 8-10 times the number of events in public places will follow, and air quality may be, General ventilation 2-5 times. Beem also can choose according to the company developed ultra-thin rectangular duct fans. In the kitchen with smoke and fumes due to the high speed impeller blades less, smoke will rapidly through the leaves, long run down the pipe fan manufacturers, only a small amount of smoke oil attached, so no need to maintain the fan two years. Thereby reducing the number of cumbersome disassembly. When the kitchen smoke fumes, smoke fumes air mixture, the temperature does not exceed 60 degrees. Furthermore, within the frame of the outer rotor motor is substantially sealed, dust, smoke, etc. will not enter the interior of the motor, so the motor outside the box will not have any impact on gas bearings, coils and other components, which sustained run, you can be assured . Hood air pressure is generally not enough, if the tube is pulled Jie Feng more common flue no effect, you can use CDF150 duct fans at the middle of the pipe pressure, wind effects can be increased by 3 times, CDF200 excellent results
