The H-3602-2-1 blower from Koller with built in 200W heater pre heats the air flow and won't cool the water down as fast or feel cold on your body, giving a far more enjoyable bathing experience.

Controlled electronically it will connect to your spa or bath control box and be operated via the top side control. Or connect it to a  PNEUMATIC 3 SPEED CONTROL BOX giving you the option to have a 3 speed blower controlled via an air button.

A powerful yet surprisingly quite 640W motor is encased in a unique vertical body making this blower great for installations into tight spots as it can be mounted either horizontally or vertically.

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

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

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