Vacuum System - Prochem LEGEND GT Operating Instructions Manual

VACUUM SYSTEM

The engine turning an air pump (vacuum pump)
generates vacuum. The air is channeled in one
side of the vacuum pump, compressed and
discharged on the opposite side, creating
airflow. This airflow 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 also heats incoming air as it
is compressed. The hot discharged air is forced
down stream into a silencer for noise abatement.
Exiting the silencer, this hot air is forced through
the heat exchanger
The vacuum pump speed is factory set to
maximize vacuum pressure and provide
sustained system life. Do not alter the vacuum
speed outside the recommended range shown
in the Technical Specifications section.
