MINDMAN MAFR401-15A-D Filter regulator

Buy online your MINDMAN MAFR401-15A-D Filter regulator from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The Mindman MAFR401-15A-D is a air filter regulator designed to provide clean, regulated compressed air for CNC machine tools and industrial automation systems. By combining air filtration and pressure regulation in a single unit, it helps ensure reliable operation of pneumatic components such as valve manifolds, cylinders, tool changers, clamping systems, and other air-powered devices.

The integrated filter removes moisture and solid particles from the compressed air supply before they reach sensitive pneumatic equipment. This helps reduce valve sticking, irregular actuator movement, premature seal wear, and other issues caused by contaminated air. The regulator section maintains a stable downstream pressure and features an adjustable setting to ensure consistent pneumatic performance during machine operation.

The MAFR401-15A-D is suitable for installation at the main machine air inlet, in local pneumatic control panels, upstream of valve islands, or within air preparation assemblies. It can also be combined with compatible lubricators to create a complete FRL (Filter-Regulator-Lubricator) air treatment system.

Key technical specifications include an operating pressure range of 0.05 to 1.5 MPa, a proof pressure of 2 MPa, and a regulated pressure range of 0.1 to 0.85 MPa for the standard version or up to 1.5 MPa for the high-pressure version. The unit operates in ambient temperatures from -5°C to +60°C (without freezing) and is equipped with a 40 μm filter element as standard, with an optional 5 μm element available. The drain bowl capacity is 70 cm³, and a PG-20 pressure gauge is supplied as standard.

Manufactured in Taiwan by Mindman, the MAFR401-15A-D is widely used on machining centers, CNC lathes, robotic cells, assembly equipment, and industrial automation systems. It is frequently selected as a replacement or spare part to restore stable air pressure and improve pneumatic system reliability. Regular maintenance, including drain removal and filter element replacement, helps ensure long service life and consistent machine performance.

Frequently asked questions about MAFR401-15A-D:

How do I confirm compatibility as a drop-in replacement
Match the port size and thread type, verify the required outlet pressure range and flow capacity, and check the body size so existing brackets and panel spacing align. Confirm gauge connection size and bowl style to keep service practices consistent across your machines.

Can this unit be combined with a lubricator to form an FRL
Yes, pair it with a Mindman lubricator of the same modular size using the correct coupling kits and brackets. Verify total flow demand and keep the same port threads to simplify installation on valve manifolds and machine inlet panels.

What maintenance practices help extend service life
Drain the bowl regularly, monitor the outlet gauge during startup and after long runs, and replace the filter element at intervals based on your air quality. Keeping upstream dryers and drains in good order will reduce regulator load and stabilize performance.
