Guidance to choosing the direct driven industrial fansThe fans can be divided into 4 groups which are type, pressure area and application.
1. Medium pressure fans : pressure area . 150-6.500 Pa. Diagram1Cleanair:Verylowdustholdingcapacity,egafterfiltration Diagram 2 Dusty air : Up to 0,2g/m³ dust content , eg welding smoke Diagram3Dustyair:Upto2g/m³dustcontent,egcuttingprocesseswithorbeforefiltration
2. High pressure fans : pressure area . 1500- 25.000 Pa. Diagram 4 Dusty air : Up to 0,2g/m³ dust content , eg welding smoke Diagram5Dustyair:Upto2g/m³dustcontent,egcuttingprocesseswithorbeforefiltration Diagram6Dustyair:Upto20g/m³dustcontent,eggranulateinformoffinerparticles.
3. Conveying fans : pressure area . 700- 15.000 Pa. Diagram 7 Material transportation: Up to 200g/m³ dust content, eg chips and granulate.
4. Plastic fans : pressure area . 40- 3.500 Pa. Diagram 8 and 9: Aggressive air: Acid –water damp, eg exhaust from fume cupboards, galvanizing tabs
The following procedure can be followed:
1. Decide mode of transport a. Clean air b. Dusty air c. Material transportation d. Aggressive air
2. For a and b the actual pressure area should be decided. Medium pressure fans up to 6.500 Pa from diagram 1,2 or 3. High pressure of up to 25.5000 Pa from diagram 4, 5 or 6.
For pressure areas of up to 6500 Pa a medium pressure fan should be chosen to begin with for price related reasons.
For c and d diagrams 7,8 or 9 should be applied, where the fan is decided by the help of desired pressure and air capacity.
3. With the desired pressure and air capacity, one should generally look for a fan curve, where opera tion point (desired pressure and air capacity) lies closely to the curves’ point of discontinuity. Here thefanwilloperatemostoptimalwiththehighestefficiency.
The following examples give some enlightenment on this:
If one regulates a fans capacity, this should be recommended with the help of a frequency converter. In which case the motor should be equipped with thermal sensors in motor winding also called PTC. These monitor the temperature of the motor winding. If winding is too high, which can happen if the motor is rotat-ing at a low speed, the motor will stop for safety reasons and can be restarted again after it has cooled down. For small motor effects the industrial fans can be delivered with a one phased motor, which can be regu-lated by a transformer.
