The Bubble Gun II is the lowest cost of all Spa King models, and is designed for use in spas of up to 500 gallons. It is typically mounted under the skirt of a spa and is electrically activated during water pumping. This pumping can be performed by a timed filtration pump or by a 24-hour water circulation pump. In most instances, Bubble Gun II requires the use of a venturi injector. By means of negative pressure, it sucks air into the water flow and through the spa's pipe systems into the spa. For achieving this venturi action, there are two injectors available: the #050 Venturi Injector or the 1 1/2" line Bypass Adapter.
