The HydroAir HA350 pump range is our most popular selling bath pump. Their versatility makes them a popular choice if you are replacing a whirlpool bath pump that you cannot get a like for like model. The HA350 range will also replace many older HydroAir pumps. They are also a great unit to replace some Chinese filtration/whirlpool pumps.
Silent running motors coupled with either self drain or centre suction wet ends make for energy efficient compact pumps. All models are fitted with a pneumatic (air) switch so on/off operation is possible either with air buttons or electronic controls. For detailed measurements and specification see documents in the downloads tab. Unions sold separately.
