## Summary description

Compressed air filter by Adler (model MAR01801) with a 1/2" reducer and an integrated automatic drain valve. Designed to remove condensate and particulates from airline systems while regulating downstream pressure via the reducer. Suitable for workshop compressors and pneumatic tools, it provides basic air treatment and automatic condensate evacuation for maintenance convenience.

## Long description

Air filter with 1/2" reducer and automatic drain valve by Adler, model MAR01801, is a compact inline compressed air treatment unit designed to remove condensate and particulates while reducing downstream pressure. It integrates a pressure reducer with a filtration element and an automatic condensate drain for continuous operation with minimal manual maintenance. The unit is suitable for basic air treatment tasks in small workshops, garage compressor installations and pneumatic tool lines where consistent, cleaner compressed air and simple pressure control are required.
Advantages
The combination of a filtration stage, a 1/2" pressure reducer and an automatic drain valve delivers three functions in a single compact assembly, saving installation space and reducing the number of separate components. The automatic drain valve evacuates collected condensate without operator intervention, lowering the need for regular manual draining. The integrated reducer provides straightforward downstream pressure regulation for pneumatic tools and equipment, while the filter element captures water and particulates to protect valves, cylinders and actuators.
Suitable for
 Small workshop compressor installations
 Pneumatic tool supply lines (grinders, impact wrenches, nailers)
 General-purpose air preparation for maintenance and hobby applications
 Feeding air to air-operated valves and cylinders in light industrial setups
Key specifications
 Connection size: 1/2" with integrated reducer
 Functionality: particulate and condensate removal plus pressure reduction
 Drain type: automatic condensate drain valve
 Mounting: inline installation for pipeline use
 Construction: metal body with transparent or semi-transparent collection bowl for condensate observation
How to use
Install the unit in the compressed air line downstream of the main compressor outlet and upstream of pneumatic equipment, observing the indicated flow direction. Secure the 1/2" connections with appropriate thread sealant or tape and mount the filter housing to a stable support if required. Adjust the reducer to the desired downstream pressure using the integrated control knob or screw, then lock the setting if applicable. The automatic drain valve will discharge collected condensate; periodically inspect the bowl for excessive contamination and clean or replace the filter element according to operating conditions.
Usage recommendations
Use the air filter with fluids and particulate loads typical for workshop compressors; avoid corrosive or combustible contaminants. For improved air quality in sensitive applications, consider adding a coalescing filter or refrigerated dryer downstream. Regularly check seals and the condition of the bowl and filter element, and drain or service the unit more frequently in humid environments to maintain performance.
