Product information

Electromechanical, irreversible geared heavy duty underground operator.

The DU.350 is a well established and popular choice amongst the professional installers. The motor combines strength, performance and importantly, reliability. With a unique square motor case, the DU.350 benefits from having seals around the motor that are elevated from the bottom of the foundation box, meaning the water depth in the box can reach up to 80mm before penetrating any motor seal.

Secondly, the unique square motor casing acts as an oil bath for the motor and the internal gearing. With the motor and the oversized mechanical gears constantly submerged in oil, this gives you maximum cooling and lubrication for longevity and high duty cycles.

Don’t look anywhere else……the DU.350 covers all your underground automation requirements.
