Guidelines For Choosing A Blower For Your Application
Normal methodology prevalent in the field is to rate the blower performance in maximum values. Like maximum flow, maximum pressure, maximum vacuum etc.
Maximum flow is realized at zero output pressure/vacuum i.e. when blower outlet is open to atmosphere, and at no restriction of blower suction port.
Maximum pressure or maximum vacuum is realized at reduced flow than maximum flow.
Each model of blower has unique performance characteristic curve for Flow Vs Pressure/Vacuum, related to design of blower and its manufacturing process and technology.
Depending of these curves, you have to choose model of blower, which meets your WORKING (DUTY POINT) parameters like flow & pressure/vacuum.
Many times user chooses blower considering maximum flow, maximum pressure/vacuum will meet their WORKING (DUTY POINT) parameters.
This is where user makes mistake, and chosen model of blower fails to meet their working parameters.
To choose correct model of blower for your application, use following guidelines
a) Estimate your application requirements like working flow and working pressure/vacuum. Do not over rate these parameters too much.
b) Get pressure/vacuum vs flow characteristic curves of different models of blowers, from different manufacturers.
c) Look up performance curves for different models of blowers, and match your WORKING parameters, and choose most suitable blower
Seek assistance from manufacturer of blowers to confirm your choice.
d) Consider any special requirements like
- Flameproof or Explosion motor
- Special working conditions like environment, temperature, location etc.
- Noise Level
- Electrical Supply
- Any other
e) Also to choose correct manufacturer of blower considering following
- Energy Efficiency : Low energy consuming blowers saves your energy input costs, which runs in sizeable value over long working life.
- Noise Level : Better designed and manufactured blowers makes lower noise.
- Maintenance : Better produced & sturdy blowers, require less maintenance attendance, saving cost and downtime.
