VEVOR Air Compressor Pump Head, 5.5HP 5.75CFM @ 90PSI, Twin Cylinder Oil Lubricated Air Compressor Piston Pump Head, Dual Stage V-Type Cast Iron Air Compressor Pump Replacement with Max. 185PSI Pressure

High-Performance 5.5HP Air Compressor Pump Head For Reliable Air Supply

The VEVOR air compressor head unit features a powerful 5.5-horsepower capacity that allows it to generate higher airflow and maintain pressures needed for driving simple and heavy-duty pneumatic air tools. It delivers a steady air supply at an output rate of 5.75 CFM at 90 PSI and a maximum working pressure of 185 PSI. This high capacity ensures a steady and abundant supply of air. It is capable of powering large pneumatic tools, industrial tasks, and more demanding applications. 

The maximum working pressure of 185 PSI provides a substantial air reserve in the tank, ensuring the compressor can operate for a longer period before the pump needs to restart. This makes it suitable for tasks where high pressure is critical, such as auto repair shops, tire inflation, spray painting, and woodworking. It is also suitable for use with simple pneumatic tools like nail guns, impact wrenches, and spray guns. 

VEVOR Air Compressor Head Unit with V-type Double Cylinder Compressor for Rapid and Efficient Inflation

The VEVOR air compressor head unit features a double-cylinder, dual-stage piston head that delivers air fast and efficiently. Unlike many single-cylinder compressors, this V-shaped double cylinder compresses air in two stages to provide a high maximum working pressure of up to 185 PSI. In the first stage, the first cylinder compresses air to an intermediate pressure, and in the second stage, air is pumped into the second cylinder, which gets compressed further to a higher pressure. 

This two-stage compression allows the tank to fill faster and reduce recovery time between cycles. This ensures a seamless and reliable supply of airflow to tools. The high maximum pressure makes it suitable for heavy-duty pneumatic tools such as impact wrenches, spray guns, and nail guns, which require strong, steady pressure. The load of the compressor is divided between the two cylinders, which lowers heat buildup inside the cylinders and minimizes wear of cylinder walls. This even heat distribution helps to extend the pump’s lifespan while ensuring smooth, long-term operation.

VEVOR Air Compressor Head Unit with Durable Cast-Iron Construction for Durability and Efficiency

The VEVOR air compressor head unit is mainly made of durable cast iron, which offers excellent wear resistance and is not easily damaged. It makes the piston head resistant to heat, wear, friction, and mechanical stress that may result from long work hours, even in high-pressure conditions. It is highly efficient, with low energy consumption, which reduces operational costs. The cast iron construction reduces the need for frequent repairs and extends the compressor’s lifespan, making it a reliable and smart investment choice for long-term use.

Belt-Driven Pulley System for Smooth Operation, Low Vibration, and Flexible Setup

The VEVOR air compressor pump head unit features a belt-driven pulley system that reduces vibration, minimizes internal part wear, and ensures a smooth, quiet operation. With a pulley diameter of 340 mm (13.38 inches) and a counterclockwise rotation design, the pulley system ensures balanced operation and effective heat dissipation during prolonged use. The dual-stage V-type design increases compression efficiency and minimizes strain on both cylinders.

For optimal performance of the pulley system, there must be precise alignment between the motor pulley and the belt pulley during installation. The more precise the alignment, the lower the vibration and noise produced. The belt-driven setup also offers flexibility in the siting of the motor. It allows the motor to be placed in any position or spot around the compressor, as long as the belt and motor pulley are properly connected to each other. 

Premium Components for Monitoring and Reliable Long-Term Performance 

Built with premium components, this oil-lubricated pump head is designed for durability and dependable performance. It features precision-machined cylinders, heat-dissipating fins, and an advanced intake and exhaust valve system that work together to ensure stability and an extended service life. An integrated air filter keeps contaminants out of the system, while the oil observation window makes it easy for users to monitor lubricant levels at a glance. This ensures smooth operation of the pump and prevents damage that can arise from low oil levels. 

These features combine to deliver long-lasting reliability and consistent performance, even in demanding conditions. The heat-dissipation fins are especially important for managing thermal stress during extended operation, reducing the risk of overheating and keeping the pump running smoothly even in tough industrial environments.

Installation and Operational Precautions for Long-Term Performance

To ensure your compressor pump head runs efficiently and safely, proper installation is essential. Start by making sure the motor pulley and the pump’s belt pulley are perfectly aligned. Even a slight misalignment can create vibrations, which accelerate wear on the bearings, belt, and pump itself. Before starting the unit for the first time, fill the crankcase with the recommended compressor oil up to the level shown in the observation mirror. Avoid running the pump without proper lubrication, and be sure to check oil levels regularly. Also, change the oil at regular intervals to prevent internal damage. Keep the intake filter clean and ensure all fittings and connections remain secure to block contaminants from entering the system.

Always let the pump build and release pressure through its normal operating cycle, and avoid disabling or bypassing safety valves or regulators. By prioritizing proper alignment, consistent lubrication, and a clean operating system, you will maximize reliability, maintain energy efficiency, and extend the service working life of your compressor pump head.
