    Air blower for spa

    Is there a way to tone down the force of the air from an air blower for a spa? The PB put in a 2 HP blower and the force of the air is almost beating you up when its on, as the wife says. Is a lower H/P blower needed or can you tune the existing one down? The spa is fine without the blower on, just don't get the massage feel that the air brings(with much force).

    Re: Air blower for spa

    I think you can just add a ball valve in the pipe below the blower and partially close it off. The blower should be able to bypass any extra air without damage.

    Although I would like for someone else to confirm this.

    Re: Air blower for spa

    Have you tried the spa with the blower removed not just off? Some spas will work just fine without a blower. Also, how far is the spa from the blower?

    Also, closing off the air flow tends to make the blower much louder so another trick is to put a tee after the blower with a valve on the bypass of the tee so that you can adjust how much air is bypassed.

    Ah ... that is a better idea on how to "bypass"/divert the air flow.

    Re: Air blower for spa

    I don't have a blower, but I do have a Jandy valve on the pipe, that I shut it off to heat faster. if I added a blower I could quite easily regulate how much air gets to the spa with the valve.

    Also drilling some holes in the pipe below the blower helps as well.
