Universal Bath Blower – Electronic – Heated/ Warm Air, Quiet Comfort – The Perfect Spa Upgrade

Product Overview

The Koller H-3602-2 Heated Air Blower (640W) is designed to enhance your spa or whirlpool experience by delivering a powerful yet quiet airflow, combined with a 200W built-in heater. Unlike non-heated blowers, this unit pre-heats the air before it enters the bath, ensuring the water does not cool too quickly and providing a more relaxing, comfortable soak.

Its unique vertical body design allows for flexible installation in both tight and standard spaces, as it can be mounted horizontally or vertically. Controlled electronically via your spa’s control box, it can also be connected to a 3-speed pneumatic control box (sold separately) for added versatility.
