## Summary description

Aerotec Air Maintenance Unit FX 3900 is a compressed air treatment module designed for systems with 1/4" (6.3 mm) fittings. It provides basic filtration, pressure regulation and condensate separation to protect downstream tools and equipment. Suited for workshops, pneumatic lines and light industrial applications where compact, inline air conditioning improves tool life and operational reliability.

## Long description

Aerotec FX 3900 is a compressed air maintenance unit designed for systems with 1/4" (6.3 mm) fittings. This compact inline module integrates basic filtration to remove particulate, a pressure regulator to set and stabilise operating pressure, and a condensate separation system to collect moisture before it reaches downstream tools and equipment. The unit is intended for workshops, pneumatic lines and light industrial applications where simple, reliable air conditioning extends tool life and reduces maintenance needs.
Advantages
The FX 3900 combines filtration, pressure regulation and condensate separation in a single compact assembly that fits 1/4" (6.3 mm) pneumatic connections. Its straightforward design allows easy installation inline with existing compressed air lines and provides stable downstream pressure for consistent tool performance. By removing particulates and separating condensate, the unit reduces wear on pneumatic components and lowers the risk of moisture-related malfunctions. The compact footprint makes it suitable for tight spaces and mobile workstations.
Suitable for
Small workshops and garage pneumatic setups
Pneumatic tool supply lines (1/4" fittings)
Light industrial machinery requiring basic air treatment
Portable or bench-mounted equipment with inline air connections
Key specifications
Connection size: 1/4" (6.3 mm) fittings
Functions: particulate filtration, pressure regulation, condensate separation
Mounting: inline installation in compressed air lines
Design: compact housing suitable for limited space environments
How to use
Install the Aerotec FX 3900 inline on the compressed air supply using the 1/4" (6.3 mm) fittings, observing flow direction indicated on the unit. Adjust the regulator knob to the required downstream pressure while monitoring a downstream gauge if available. Periodically check and drain accumulated condensate according to operating conditions; if the unit uses a manual drain, open it at regular intervals and close securely after draining. Replace filter elements as recommended by your maintenance schedule or when airflow or pressure performance degrades.
Usage recommendations
Use the FX 3900 in systems with compatible 1/4" fittings and within the pressure range specified by your pneumatic tools. Keep the unit accessible for routine draining and filter checks. Avoid exposing the unit to freezing temperatures or corrosive environments; if such conditions are present consider additional protection or more advanced conditioning equipment.
