Air pressure regulator Aerotec 9051091 — single-piece regulator for compressed air systems

Aerotec air pressure regulator 9051091 is a single-piece regulator designed to control and stabilise compressed air pressure in pneumatic systems. Supplied as a complete unit, it integrates the regulating mechanism and connection ports into one compact housing, allowing consistent downstream pressure for air tools, valves and actuators. The regulator is intended for use in workshops and light industrial environments where straightforward installation and dependable pressure control are required.

Advantages

The single-piece construction reduces potential leak points and simplifies installation compared with multi-component assemblies. The unit provides steady pressure regulation to protect downstream equipment and maintain consistent tool performance. Its compact design saves space in pneumatic panels and service blocks, while durable materials and a stable control mechanism contribute to long service intervals and reduced maintenance needs.

Suitable for

• Air-operated hand tools and pneumatic wrenches
• Pneumatic control valves and actuators
• Compressed air distribution in workshops and production lines
• General-purpose industrial and light-industrial pneumatic applications

Key specifications

• Single-piece regulator housing for simplified installation
• Designed for compressed air systems and pneumatic circuits
• Compact footprint suitable for inline or panel mounting
• Stable pressure control to protect downstream components
• Durable construction for routine industrial use

How to use

Install the regulator in the compressed air line following the flow direction marked on the unit, ensuring correct port alignment and secure threaded or push-in connections. Set the desired output pressure using the adjustment control while the upstream supply is pressurised, then lock the setting if a locking feature is provided. After installation, verify downstream pressure under typical load conditions and check for leaks at connections. Periodically inspect the regulator for signs of wear, contamination or loss of regulation and perform maintenance or replacement as required.

Usage recommendations

Use clean, dry compressed air and fit an upstream filter and lubricator if required by downstream equipment. Avoid exposure to corrosive fluids and extreme temperatures. Match regulator mounting orientation and connection type to your system layout and verify compatibility with maximum operating pressure of the compressed air supply.
