4.25 Blower Trainer


Note : All machine configuration and specification are subjected to change without advance notice for better quality of product.

General Description :
The equipment is portable size, compact designed instrument, competitive in price and performance. It consists of DC drive small blower, two set of inclined manometers, fan speed controller , rpm indicator and torque measuring device. Fan static pressure,total pressure, torque interm of N-m and fan speed are direct measurement.

Experimental Capabilities :
  1. Study the fan performance curves.
  2. Contruct the curve between air flow rate,Q , SP AND delta SP so that the optimum working range can be obtained.
  3. Comparision of mechanical efficiency obtained from experiment and theoretical efficiency.
Technical Specifications :
  1. Blower: Sirocco type, rpm up to 3100, >= 0.04 m3/sec@ 25mmWG.
  2. Driven motor: DC 24 Volts brushless motor, >=100 Watts.
  3. Manometers: 2 sets of 5 degree inclined manometer scale readable to 1 mmWG.
