4ZM03 SPEEDAIRE Filter Regulator Lubricator

Review SPEEDAIRE Filter/regulator/lubricator To 150 Psi

Introducing the Speedaire 4ZM03 Filter/Regulator/Lubricator for your 150 psi air compressor, a crucial accessory designed to enhance the performance and longevity of your compressor system. This compact yet powerful component is engineered to filter, regulate, and lubricate the compressed air flow, ensuring consistent air quality and optimal machine operation.

The filtering function of this device is essential for removing contaminants from the air stream. The 4ZM03 comes with a replaceable, high-efficiency, and large-capacity, 5-micron air filter, designed to trap particles as small as 5 microns in size. This helps to prevent damage to tools and equipment, as well as reduce wear and tear on compressor components.

The regulator aspect of this unit maintains a steady and consistent air pressure, ensuring that your tools receive the optimal air pressure required for efficient operation. The 150 psi maximum operating pressure enables compatibility with a wide range of pneumatic tools and applications.

Lastly, the lubricator feature provides oil to the air intake, ensuring that the compressor piston rings and other moving parts are adequately lubricated. This not only increases the compressor's overall efficiency but also helps to prolong its lifespan by reducing wear and tear.

The 4ZM03's robust design includes a heavy-duty, cast-iron housing for durability, and a conveniently located sight glass for easy oil level monitoring. Its versatile connection options include both male and female threaded connections, providing flexibility in installation.

With the Speedaire 4ZM03 Filter/Regulator/Lubricator, you can enjoy reliable, clean, and lubricated air flow for your compressor system, ultimately improving tool performance and prolonging the life of your compressor.

The Speedaire 4ZM03 is a filter regulator lubricator (FRL) unit designed for compressor systems.
