Centrifugal type "snail" industrial fan V-2E-130QD, supply voltage 230 VAC with power 155 W, working opening 116x96 mm and flow 240 m3/h. It is possible to reduce the fan flow rate with a properly selected frequency regulator.
Centrifugal fans are used when high flow rates are required. Low operational noise is an advantage when placed in ventilation installations or ducts in industrial halls or public buildings. It is important, when choosing this type of fan, to take into account its characteristics so that they correspond to the particular application.
The fans are intended for working in normal weather conditions as the ambient temperature is from -40°С up to +60°С and the air humidity at 30°С – from 40% up to 85% with altitude up to 1000m. With degree of protection IP44 the fan is not suitable for operation in high humidity areas, confined spaces and bad weather conditions.
It is not allowed for the fan to work in conditions where vacuum may be created for example if the fan is used to pull out air from a room in which there is no other air source. Thus the motor of the fan cannot cool itself and will be broken down.
The RPM can be regulated using a frequency inverter or a phase regulator and It is possible to adjust the fan speed by means of a frequency inverter or by phase adjustment with a reduction of the speed up to 75%. The fan can not be powered by a DC / AC inverter with a modified sinewave - this will cause it to malfunction.
