Pressure regulator Aerotec FX 3700, 1/8" inlet/outlet, model 2010218

The Aerotec FX 3700 pressure regulator with 1/8" inlet/outlet (model 2010218) is designed to control and stabilize compressed air pressure for pneumatic tools and systems. It provides precise downstream pressure regulation, helping to protect air-operated equipment from pressure spikes and ensuring consistent performance in workshop, industrial and maintenance environments. The compact brass-bodied regulator integrates into compressed air lines where a small footprint and reliable adjustment are required.

Advantages

The regulator offers stable pressure control with fine adjustment capability and a clearly marked adjustment knob for repeatable settings. Its construction provides corrosion resistance and long service life under typical workshop conditions. The 1/8" connections allow easy integration into existing pneumatic lines and fittings. Designed for straightforward installation and minimal maintenance, the unit ensures consistent air delivery to downstream tools and valves.

Suitable for

• Pressure regulation for handheld pneumatic tools (grinders, impact wrenches, air ratchets)
• Control of air supply to small pneumatic actuators and cylinders
• Use in compressed air maintenance panels and local service points
• Workshop and light industrial process lines requiring compact regulators

Key specifications

• Connection size: 1/8" inlet and outlet
• Type: single-stage pressure regulator for compressed air
• Body material: corrosion-resistant metal (brass or similar)
• Adjustment: manual knob with pressure scale for fine tuning
• Mounting: in-line installation in pneumatic tubing or fittings
• Intended medium: filtered compressed air (dry, oil-free or oil-mist depending on system requirements)

How to use

Install the Aerotec FX 3700 regulator in-line with the compressed air supply, observing correct flow direction if marked. Connect the 1/8" inlet and outlet to compatible fittings or tubing, ensuring leak-free joints. Gradually open the supply valve, then adjust the knob to set the desired downstream pressure while monitoring a pressure gauge downstream of the regulator. Make small incremental adjustments and allow the system to stabilize before finalizing the setting. Periodically check for leaks and verify pressure settings as part of routine maintenance.

Usage recommendations

Use clean, filtered compressed air and consider installing a filter or lubricator upstream if required by downstream equipment. Avoid exposing the regulator to freezing conditions or corrosive atmospheres. Follow regular inspection intervals, clean or replace seals if leakage develops, and ensure pressure settings remain within the operational range of connected tools and actuators.
