Features: 1.The accumulator tank holds a reservoir of air and water down stream from the pump. The air acts as a cushion, absorbing pressure variations creating a smoother flow and reducing the cycling of the pump,especially at lower flows. 2.Low power consumption, no noise during use, avoiding frequent opening of the safety valve and frequent refilling of the automatic water replenishment valve. 3.Good sealing, waterproof and dustproof, compact design, small in size, detachable, easy to carry and install. 4.Small pressure fluctuation range, safety and reliability, energy saving, has stable performence. 5.Maximum inlet pressure is 125PSI, capacity is 0.75L, pressurized water system for yachts / RV / boats. 6.Can be used for yacht/RV/caravan pressurized water system, sprayer fixtures (vehicle?mounted and electric sprayer), clean machine, humidifier, water purification, food beverage filling and liquid transferand any other pressurization system.
