General Description

Functioning
The Toftejorg SaniMidget Retractor consists of 2 main parts: The drive unit and the base housing. The
base housing includes the piston with the cleaner head.
Media driven
In the cleaning media operated version the
cleaner head extends from the pressure of the
cleaning media and is retracted by a spring.
The cleaning media is directed through the 1” tri-
clamp inlet connection into the housing. The liquid
pressures the piston, which moves forward to
extended position. At the same time the liquid
passes through drillings in the piston to the
cleaner head and out through the slots.
When cleaning is completed the machine is
automatically retracted by an integrated spring
system.
For total drain of the machine the retraction of the
cleaner head can be delayed by adjusting the
evacuation of air behind the piston. Use a
screwdriver and adjust the needle valve on the
rear part of the machine to correct position.
Pneumatic driven
In the pneumatic operated version, the cleaner
head is extended and retracted by an integrated
pneumatic cylinder. The cleaner head is extended
when air is applied to the pneumatic cylinder,
which must be done before cleaning media supply
has started. It is retracted to its initial position
when cleaning is completed by diverting the air
pressure from the pneumatic cylinder. The
pneumatic cylinder can remain extended during a
draining phase without media supply.
