4-5HP Heavy Duty Air Compressor Pump, 3-Cylinder 10-12 CFM Cast Iron Compressor Pump w/Triple Air Filters, Industrial & Construction Machinery Replacement, High-Efficiency Low Energy Consumption

"DescriptionThis air compressor pump has high hardness, tensile strength, and compression resistance, allowing you to use them with peace of mind. The powerful heat dissipation performance enables it to quickly cool the machine. The air filter muffler can ensure low noise operation of the machine. DetailsThreaded Oil Cap: It helps to achieve convenient and tight connections to avoid oil leakage.Standard Pulley: It plays a balance and correction role to avoid bearing displacement, making the machine run smoother.ApplicationIt is widely used in the chemical industry, light industry, textile, electronics, machinery, mining, construction, etc.SpecificationMaterial: Cast Iron, AluminumPower Source: ElectricCylinder: 65mm*3Maximum Working Pressure: 0.8MPa/115PSIMaximum Speed: 1030rpm (Matching the Overall Machine Speed)Exhaust Volume: 0.36m³/min/12.7cfmPipe Interface: 19mm/ 3/4inMatching Motor Power: 3KW/4HPGross Weight: 21kg/46.29 lbsPackage Size: 44*33*38cm/17.32*12.99*14.96inPackage Included1*Air Compressor Pump3*Air Filter MufflersNotes1.Note: The pulley speed should not exceed 1000r/min. 2.It should match the motor power. Please pay attention to the product specifications before ordering.3.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.4.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.5.The new machine must be filled with engine oil before starting(Special engine oil for air compressors must be used), and the engine oil shall be added to the center of the red point of the oil mirror. Please change the oil for half a month for the first time, one and a half months for the second time, and change the oil for the next four to five months. Please pay attention to observation at ordinary times. If it is not enough, replenish it in time.

• 【Heavy-Duty Construction】Cast iron & aluminum alloy body with anti-rust paint ensures extreme durability. Reinforced crankshaft and 65mm cylinders enhance structural rigidity, resisting wear/corrosion for 30% longer lifespan than standard pumps.
• 【Multi-Pump Efficiency】3 independent pump heads with individual controls allow simultaneous air supply to multiple devices. Isolate faulty units without shutting down entire operations - ideal for production lines requiring 10-12 CFM airflow.
• 【High-Performance Operation】Oversized crankcase reduces vibration by 45%, paired with dual iron vent nozzles and aluminum cooling pipes. Maintains stable 5HP output with rapid inflation while preventing oil leaks.
• 【Energy-Saving Design】Multi-pump pressure distribution cuts energy consumption by 35% vs single-head compressors. Integrated cooling fins dissipate heat 50% faster, reducing motor load for sustained efficiency.
• 【Quiet & Easy Installation】Triple muffler air filters lower noise to 68dB. Pre-drilled base holes enable bolt-on setup in 15 minutes - perfect for workshops/construction sites."
