Whisper Quiet mobile whirlpools have self-lubricating underwater bearings that would not freeze up even if operated without water! These turbines are made with thick, chromium nickel and copper plating on heavy bronze castings and tubing. Both water pressure and velocity can be controlled. Dakon whirlpools are constructed with a heavy, 18-gauge stainless steel outside skirt and an even thicker 16-gauge inner wall, that provide extremely strong double-walled sides. The seamless inner wall is arc-welded to a fully covered bottom, and ground and polished to a satin finish. The 1/2 h.p motors are UL, C-UL and C.E. listed for 115 volt service. Shipping discounts do not apply. 32in long x 16in wide x 25in deep (81 x 41 x 64cm). Approx. 45 gal. (171 liter) capacity.
