The D15 model rotary joint has two independent channels for clutch operation and for the pistons of the air and oil sprinkler.

To avoid possible confusion, the same type of fluid must pass through two separate channels.

When operating with compressed air, the maximum pressure of D15-302-03F is 10 kilograms and the maximum rotational speed is 1500 revolutions.

When evacuated, the maximum pressure of D15-302-03F is 6.7 kilograms and the maximum rotational speed is 1500 revolutions.

When lubricating with hydraulic oil, the maximum pressure of D15-302-03F is 10 kilograms and the maximum rotational speed is 3500 revolutions.
