Cylinder diffusers may be used in both vertical and horizontal applications if required. Also they can be used for heating and cooling applications and are specifically designed for use in large areas such as shopping malls, gymnasiums etc. areas where it is desirable to have a controlled ventilation but with a long throw.
The main cylinder spins on a pivot allowing it to move vertically up or down and the individually adjustable vertical pattern control blades can be altered to any angle to allow a wide spread throw.
