Notes edit an air can not contain corrosive, viscous media can not contain. 2, medium temperature does not exceed 80 ℃, not lower than -10 ℃ 3, medium or hard-containing dust particles should not exceed 150mg / m3 4, be careful not to B-type fan used for firefighting purposes. 5, system design and fan selection should be made by professionals, and the system as much as possible to accurately estimate the negative force, otherwise it will lead to improper selection of the actual use of ineffective fan. 6, the pressure loss in the resistance component of the system is not a fixed value, Shandong new wind ventilators, should be used to calculate the drag coefficient for selection. 7, the cabinet should not be in full form of the fan (ie the fan inlet and outlet pipes are not connected) under the long run, because in such a strong fan performance state is unstable, and in this case, the fan Standard configuration of the motor is in overload status, long-term use can lead to destruction of the motor, a short test machine is allowed fresh air energy recovery ventilator is an energy-efficient air conditioning and ventilation installation of new wind ventilators, divided CHA total heat recovery CHB type and sensible heat recovery type, its core function is to use the indoor and outdoor air temperature difference and humidity difference sensible heat fresh air ventilators, good movement transducer characteristics through energy recovery fresh air ventilator full hot, bi displacement ventilation in at the same time, generate energy exchange, making effective access to fresh air ventilation in the enthalpy (total heat type) or temperature (sensible heat type), thus saving energy consumption of fresh air pretreatment to achieve the purpose of energy saving ventilation, energy saving the effect is very significant. Over the years of technical research and development, successfully developed the third generation of new wind energy recovery ventilators, its movement using the latest technological achievements - Energy Recovery Module WASSI-III, WASSI-III superior performance of the third generation of new wind energy recovery change air machines on the technical indicators are beyond the previous models, the most competitive on the market fresh air ventilator products. Hunan new wind ventilators, new wind ventilators, ventilation equipment from Plumper Plumper Shandong Dezhou ventilation plant. Dezhou Plumper ventilation plant (www.frtfsb.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
