The JOHN R. ROBINSON, INC JR3800 Tube Cleaner makes tube cleaning a safe, simple one man job. While a tool rotates through the tube, driven by a flexible shaft, water assists by flushing out loosened deposits. Tubes are left clean and free of energy robbing build-ups of scale, algae, mud, etc.

HOW IT WORKS

The Robinson 3800 Tube Cleaner was designed with a flexible shaft which rotates at speeds from 0 to 1800 RPM inside a watertight nylon casing. As the shaft is fed into the tube being cleaned, water from a garden hose is carried thru the machine to the brush or cutting tool. The brush or cutting tool loosens deposits in the tube and water assists in flushing deposits out the end of the tube. Operation of the machine is controlled by an air actuated foot switch. Step on the switch - the shaft rotates and water flows thru the casing. Lift the foot of the switch - the shaft immediately stops rotating and water stops flowing. Thus - the machine operates and water flows only when the operator deliberately depresses the foot switch!

CONSTANT TORQUE • VARIABLE SPEED • INCREASED SAFETY

JOHN R. ROBINSON, INC. has carefully designed the 3800 Tube Cleaner with operator safety and equipment reliability in mind. The unit is powered by a D.C. (Permanent Magnet) motor. The motor is combined with a solid state speed control. This combination allows the operator to select rotational speeds from near 0 to 1800 RPM with a constant torque. Thus, the operator can handle the shaft and tools at a safe comfortable speed for the condition of the tube being cleaned. This feature cannot be offered on units with A.C. motors and constant high RPM's.

SEVERAL MODELS AVAILABLE TUBE CLEANERS WITH UNIVERSAL SHAFT COUPLERS
R1200 Tube Cleaner - Constant Speed w/Foot Control
Designed for applications where variable speed and/or reverse rotation is not desired or budget restraints demand a more economical unit.
R1200-50 Same as R1200 except 220V, 50HZ
JR3800 Tube Cleaner - Variable Speed w/ Foot Control
