VACUUM SYSTEM
The engine turning a vacuum/blower generates
airflow. The air is channeled in one side of the
vacuum/blower, compressed and discharged on the
opposite side, creating a vacuum.
The vacuum 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/blower.
The vacuum/blower 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 the hot
air and gases from the engine. This mixture of hot
air and 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.
The engine and blower speeds are factory set to
maximize vacuum pressure and provide sustained
system life. Do not alter the engine or vacuum
speeds outside the recommended ranges shown in
the Technical Specifications section.
