The 3604/1 blower from Koller with built in air switch means it can be controlled electronically or via the press of an air button.

A powerful yet surprisingly quite 440W motor is encased in a unique vertical body making this blower great for installations into tight spots.

Another great feature on this blowers is that it can be mounted via 1 bolt on the removable central mounting clip. With this you can then mount the blower not only vertically but also horizontally.

A standard 1 ½" buttressed connection provides a wide range of union options.

These blowers will usually always plug into the control box of your hot tub, bath or spa. 

They are supplied with a bare cable so its a good idea to re-use your original cable for easy of re-fitting to the control box.
