Leo Mac 550 / 550W 230V Booster-Intelligent Pressure Pump Only
15551
The LEO MAC550 is an intelligent pressure booster system featuring a variable-speed permanent magnet motor that automatically adjusts performance according to water demand, providing constant pressure to all taps at all times. Designed as a complete all-in-one solution, the MAC550 integrates a high-efficiency pump, non-return valve, pressure sensor, and speed controller in a single compact unit for easy installation.
The energy-efficient permanent magnet frequency-converting motor continuously adapts its RPM to match the required outlet water flow, eliminating energy waste and reducing electricity bills. With a sound level below 70 dB(A), the MAC550 operates quietly, and its touch control panel displays working pressure and fault codes for simple diagnostics and adjustment.
