SPS90-3

Wide voltage permanent magnet VFD booster for steady pressure from rooftop tanks and mains supply lines.

The SPS90-3 runs across a wide voltage range with a water cooled motor and controller, keeping noise low and motor efficiency high. A stainless steel precision cast body with ceramic shaft and bearing protects the water path, while the two button interface and smart fault diagnosis keep operation simple for household boosting and light transfer duty.
