Pressure regulator Aerotec FX 3100 1/4" (6.3 mm) – inline pneumatic pressure control

Aerotec FX 3100 is a compact inline pneumatic pressure regulator with a 1/4" (6.3 mm) connection designed to set and maintain a stable output pressure in compressed air systems. The regulator is intended for integration into pneumatic supply lines to deliver predictable pressure to air tools, valves and instrumentation. Its in-line form factor and straightforward adjustment mechanism permit installation in confined spaces and simplify downstream pressure control and equipment protection.

Advantages

The Aerotec FX 3100 provides precise pressure regulation with minimal footprint, reducing pressure fluctuations and protecting downstream components. Its inline configuration allows direct placement into existing tubing runs without the need for bulky manifolds. The adjustment knob offers intuitive control and fast set-up, while robust construction ensures durability in workshop and light industrial environments.

Suitable for

• Regulating supply pressure for pneumatic hand tools and spray guns
• Feeding stable pressure to pneumatic valves and actuators
• Providing controlled pressure to instrumentation and sensors
• Local pressure adjustment in compressed air distribution lines

Key specifications

• Connection size: 1/4" (6.3 mm) inline port
• Function: adjustable output pressure regulation for compressed air
• Mounting: inline installation within pneumatic tubing or piping
• Adjustment: manual rotary knob for setting desired pressure
• Construction: metal body with corrosion-resistant finish (suitable for workshop use)

How to use

Install the Aerotec FX 3100 directly in the compressed air line with correct flow direction and secure the 1/4" connections according to the tubing or fitting type used. With the supply pressure present, turn the adjustment knob to set the required downstream pressure while monitoring with a pressure gauge placed after the regulator. Make incremental adjustments and verify stability under working load. Ensure system is depressurized before removal or service.

Usage recommendations

Use clean, dry compressed air and appropriate filtration upstream to prolong regulator life; avoid exposure to corrosive environments and perform periodic inspection for leaks and correct setting. For critical applications, pair the regulator with a downstream gauge and consider additional filtration or lubrication as required by connected equipment.
