VACUUM SYSTEM
The engine turning an air pump generates vacuum.
The air is channeled in one side of the vacuum
pump, compressed and discharged on the opposite
side, creating airflow.
The movement of air is used to do the work
necessary for the extraction process. A vacuum
nozzle applied to the carpet surface removes
moisture, dirt and spent chemicals. These elements
are conveyed back to a separating tank utilizing
hoses and the force of air. Particles of moisture and
dirt are separated in the vacuum tank using a series
of changes in direction and velocity. The air is then
filtered and rushes into the vacuum pump.
The vacuum pump compresses and heats the
incoming air. The hot discharged air is forced down
stream into a silencer for noise abatement. After
exiting the silencer, this hot air is mixed with hot
gases from the engine. This mixture of hot gases are
then forced through 3 radiators serving as heat
collectors. Heat from the engine and vacuum pump
is then transferred into the plumbing system raising
the water temperature for better cleaning.
