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.
