Air Compressor Pump Head 175PSI 5.5HP Twin Cylinder Air Compressor Pump Head 4KW Double Stage Universal Low Energy Consumption Air Compressor Head Faster Inflation & Low Noise (2.2KW, 3HP, 115PSI，A)

• 💪【High Efficiency】This pump head features an extended cylinder (3.54" in diameter), a maximum air supply of 11CFM, a high speed of 800rpm, and a discharge pressure of 175 PSI. It is powered by a 3HP motor and has an ASSAB special valve steel hair piece, which improves gas supply efficiency.
• 💪【Premium Material】This pump head is constructed of cast iron, which provides it with high strength and good rigidity. After painting, polishing, and plastering processes, it is resistant to wear, corrosion, and rust, ensuring excellent performance and a long service life.
• 💪【Smooth Running】This pump head's belt drive design, featuring a standard pulley, serves to balance and correct the machine's performance, preventing bearing displacement and resulting in smoother operation.
• 💪【Cooling & Low Noise】The copper-plated aluminium tube and evenly distributed heat dissipation fins on the outside make the machine dissipate heat faster, ensuring stable operation. The pump head has two air filters and two silencers to filter moisture from the air, which speeds up inflation and reduces noise.
• 💪【Wide Applications】This pump head is widely used in the chemical industry, light industry, textile, food processing, health, electronics, machinery, mining, construction, scientific research, factory, auto repair, and others.

Specifications: Air delivery: 8~11CFM Rated pressure: 175 PSI (1.16MPa) Driving power: 4KW (5.5HP) Pump speed: 800RPM Cylinder diameter: 3.54" (90mm) Distance of screw hole: 26cm*14cm (10.2"*5.5") Rated exhaust volume: 0.6L/Min Note: If the motor speed is 2880rpm, the diameter of the motor wheel is 10 cm. If the motor speed is 1440rpm, the motor wheel is 20 cm Features: High efficiency, high precision, universal, low energy consumption. High quality material, not easy to damage. Strict balance support and correction to ensure the smooth operation of the main engine. Special valve steel is used for hair piece, which has good strength and toughness at high temperature. Faster inflation and low noise. Strong cooling blade, good cooling performance. Installation notes: 1、 When placing the pump head, the motor pulley and the belt pulley must be in the same straight line. The more aligned, the less vibration. 2、 Tighten the screws (including the base and pulley screws). 3、 After the screws are installed, the belt shall be tightened. If the belt is loose, please move the motor. After the screws are tightened, reinstall the belt. 4、 The new machine must be filled with engine oil before starting, and the engine oil shall be added to the center of the red point of the oil mirror. 5、 The rotation direction of the pump head is clockwise. If it reverses, please adjust it in time. 6、 Change the oil for the first half month, the second one and a half months, and the next two to three months. 7、 Replace the air filter regularly. Under normal conditions, it must be replaced in two to three months, and in case of poor environment, it must be replaced in one month. 8、 The operation of the machine will produce high temperature, be careful not to burn!
