Whisper Quiet mobile whirlpools have self-lubricating underwater bearings that would not freeze up even if operated without water! 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, providing extremely strong double-walled sides. 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. 25in long x 14in wide x 16in deep (64 x 36 x 41cm). Approx. 16 gal. (61 liter) capacity. Tank bottom 14in (36cm) above floor.
