Air compressor accessory Proline 66387 — maximum inlet pressure 9.3 bar, 1 piece

Proline 66387 is an air compressor accessory supplied as a single unit and designed to regulate working pressure while providing clean, dry air and appropriate lubrication to pneumatic tools. The component is intended as a replacement or spare part for compatible compressed-air systems and supports standard pneumatic connections. With a specified maximum inlet pressure of 9.3 bar, it is suitable for workshop maintenance, tool hookups and routine compressed-air system repairs.

Advantages

This accessory provides controlled pressure regulation to protect pneumatic tools and maintain consistent output. It conditions incoming air by reducing moisture and particulate contamination while allowing for proper lubrication of downstream tools. The single-piece supply simplifies replacement and inventory management, and compatibility with common pneumatic fittings makes installation straightforward in most workshop environments.

Suitable for

• Workshop maintenance and repair of compressed-air systems
• Connection and protection of pneumatic hand tools and air-powered equipment
• Replacement of worn or damaged pressure regulation and air-conditioning components
• General-purpose compressed-air installations that require pressure control and air conditioning

Key specifications

• Maximum inlet pressure: 9.3 bar
• Supplied quantity: 1 piece
• Function: pressure regulation, air filtration/drying and tool lubrication support
• Compatibility: designed for standard pneumatic connections and workshop compressors

How to use

Install the accessory inline with the compressor outlet and downstream tool lines following the compressor and tool manufacturer instructions. Ensure the system is depressurized before connecting or disconnecting fittings. Adjust the working pressure to the required set point within the accessory’s range and verify that filters, drains and lubrication ports (if present) are properly configured. Perform a leak test after installation and check that air delivered to tools is clean, dry and correctly lubricated.

Usage recommendations

Regularly inspect seals and connections for wear or leaks, replace filter elements and drain condensate as specified by your maintenance schedule, and use manufacturer-recommended lubricants to maintain tool performance and prolong component life.
