## Summary description

Compressed air maintenance unit combining a filter, pressure reducer and oiler with 1/2" connection and an automatic drain valve. Designed to remove condensate and particulates, regulate outlet pressure and provide controlled lubrication for pneumatic tools and systems. Suitable for workshop and industrial use where clean, regulated and lubricated compressed air is required.

## Long description

Filter with reducer and oiler 1/2" with automatic drain valve from Adler is a compact compressed air maintenance unit that integrates air filtration, pressure regulation and metered lubrication in a single assembly. The device removes condensate and solid particles, stabilizes downstream pressure and introduces controlled oil mist to protect pneumatic components and extend tool life. The 1/2" connection size and built-in automatic drain valve make it suitable for installation in workshop and light industrial compressed air lines where reliable, low-maintenance conditioning is required.
Advantages
The combined design reduces the need for separate components and minimizes installation space. Integrated filtration captures water and particulates before they reach downstream equipment, while the pressure reducer provides accurate and repeatable outlet pressure for consistent tool performance. The oiler supplies adjustable lubrication to pneumatic motors and cylinders, helping prevent dry running and reducing wear. An automatic drain valve removes accumulated condensate without manual intervention, lowering maintenance frequency.
Suitable for
 Workshop compressed air lines for pneumatic tools
 Industrial pneumatic systems requiring regulated pressure and lubrication
 Assembly stations with air-operated actuators and cylinders
 Maintenance bays and service units where condensate removal is important
Key specifications
 Connection size: 1/2"
 Functions: filtration, pressure reduction, lubrication
 Drain type: automatic condensate drain valve
 Mounting: inline mountable unit suitable for horizontal or vertical pipe runs (manufacturer recommended orientation may vary)
 Construction: metal and polymer components designed for compressed air systems
How to use
Install the unit in the compressed air line upstream of the equipment to be protected, observing correct flow direction. Connect using appropriate fittings for a 1/2" port and ensure piping is clean before installation. Adjust the reducer to the required outlet pressure using the regulator knob; verify pressure with a gauge. Set the oiler to supply the minimum effective lubrication for connected pneumatic tools — start with a low setting and increase gradually while monitoring tool performance. Periodically check the transparent bowl or sight window for accumulated condensate and particulates; the automatic drain will evacuate condensate, but manual inspection ensures early detection of unusual contamination.
Usage recommendations
Use clean, dry compressed air upstream when possible and fit a coarser pre-filter for heavy contamination. Follow periodic inspection intervals based on operating hours and environmental conditions, replace filter elements per manufacturer guidance, and use compatible pneumatic oil for the oiler to avoid component buildup. If operated near freezing temperatures or in highly contaminated environments, consider additional air treatment or more frequent maintenance.
