Festo Filter Regulator, 2 to 12 Bar Operating Pressure, 1500L/Min Standard Nominal Flow Rate - MS4-LFR-1/4-D7-ERV-AS

Step up the efficiency of your pneumatic system with this two-in-one filter regulator from Festo. The 40μm filter cleans compressed air to prevent clogging and friction damage, extending the lifespan of your equipment. An automatic drain opens and closes in line with fluid levels to keep contaminants out of your supply. By controlling pressure, the regulator stabilises outputs to ensure consistent performance and reduced service interruptions. Thanks to a wide operating pressure range between 2 and 12, you'll find this is a versatile choice.
