When installing suction fan, the fan side of the wall must be well sealed. Especially surrounding the fan can not have gaps. The best way to install suction fan is suction fan impeller, fan nearby walls and doors that face all off, fans across the wall of windows and doors open to ensure airflow straight line flow. Suction fan installation is a very important project for the future use of suction fan effect is very large negative impact of fan series, you must keep in mind throughout the process installation. Adjustable suction fan inlet vane manufacturers, FC (forward multi-blade) fan adjustment feature (after the wing) fans better than BI (backward plate) / AF. Although less efficient than FC fan standalone BI / AF fans, but in VAV system suction fan, fan power is reduced because of the good characteristics of FC, both the power consumption is almost the same, plus a small, lightweight FC fan has a low number of revolutions advantage, making it the VAV system more widely. BI / AF fan because of the size of the weight of the price over FC fans in the same rating occasions, with a high number of revolutions of the shortcomings, it limits its application in small VAV system, but in large and medium load applications, the use of high efficiency still hope The BI / AF-type fan.
