Easy maintenance

SafetyEasy installation

Fluid flow from low flow rate
(2 L/min) can be visually checkedwith the rotating two-coloredimpeller.

Flow Vane ASSY can be replaced
without removing it from thepiping (both models).

The stopper prevents unintended
removal of the plastic parts.

The installation and replacement
is easy since the screw part of T2side rotates freely to the left andright.

replacement timeof Flow Vane ASSY

Specifications

The recommended replacement time for this product is calculated
based on the amount of wear on the internal parts of the Flow Vane
ASSY. Refer to the table below for the recommended replacement time.
*The durability varies depending on the usage environment andconditions. (pressure, temperature, etc.)

Flow rate (L/min)

If the Flow Vane ASSY is dirty
or cloudy and the impeller isdifficult to see, replace it
regardless of the recommended
replacement time.
