Air Compressor

Description Note: The pulley speed should not exceed 1000r/min.
Description:
This 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. It will be a good assistant for you to improve working efficiency.

Notes:
- It should match the motor power. Please pay attention to the product specifications before ordering.
- 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.
- 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.
- 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.
- The rotation direction of the pump head is clockwise. If it reverses, please adjust it in time.
- Please replace the air filter regularly. Under normal conditions, it must be replaced in two to three months, and in case of a poor environment, it must be replaced in one month.
- The operation of the machine will produce high temperature, please be careful not to burn!
- Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement and make sure you do not mind before ordering. Product Highlights HEAVY-DUTY CAST IRON CONSTRUCTION: Built from high-strength cast iron and aluminum components with protective painting finish, this air compressor pump head resists wear, corrosion, and rust. The robust construction ensures excellent performance and extended service life in demanding industrial environments and workshop applications.

HIGH-EFFICIENCY THREE-CYLINDER DESIGN: Featuring three 65mm cylinders with extended stroke design, this compressor pump achieves rapid inflation with 0.36m³/min (12.7 CFM) exhaust volume. The large crankcase promotes smoother operation and reduces oil leakage while maintaining 0.8MPa (115 PSI) maximum working pressure.

ADVANCED HEAT DISSIPATION SYSTEM: Equipped with dual iron breathing nozzles and aluminum cooling tubes with distributed fins, this pump head dissipates heat rapidly during operation. The efficient cooling system reduces internal pressure and temperature, ensuring stable performance and extending the pump's operational lifespan.

ENERGY-EFFICIENT LOW-NOISE OPERATION: Compared to single pump heads, this multi-cylinder design reduces individual pump pressure and flow requirements, lowering overall power consumption. The integrated air filter mufflers provide silencing function for quieter operation, creating a more comfortable working environment.

SIMPLE INSTALLATION & VERSATILE APPLICATION: Featuring an integrated structure with pre-drilled mounting holes, this replacement compressor pump installs easily onto compatible systems. The universal design suits various industries including chemical, textile, manufacturing, construction, automotive repair, and electronic production applications.
