The apparatus consists of a two stage Air Compressor which is driven by an induction motor. It sucks air
from inlet air tank through an orifice and air filter. The air is compressed in two stages. The
compressed air from stage one enters through inter-cooler to the stage second. The finally compressed
air is stored in the air receiver. Delivery pressure gauges one after first stage and another after
second stage is fitted. The temperature sensors are fitted to measure the temperature at different
stages. Energy meter is fitted to measure input to motor. These measurements equipment are provided to
perform.

The blowers are used to supply the air mainly in furnaces for burning the fuel. The blowers depending
upon their impellers are of following types:
• Radial Curved Vanes
• Forward Curved Vanes
• Backward Curved Vanes
Specifications:
The unit consists of:
• AC motor of 1 HP at 1400 RPM is coupled to the impeller.
• Arrangement is provided to change the impeller to perform the experiment with all the three impellers
i.e radial, forward and backward.
• RPM Contact type Tachometer is provided on the control panel to measure the RPM.
Voltmeter and Ammeter are provided on control panel.
• Outlet pipe of 50mm dia with 2 meter length is fitted. A butterfly valve is used to control the
discharge.
