New Original Festo 574028 MS4-LR-1/8-D5-AS Air Pressure Regulator
1. Product Overview
The Festo MS4-LR-1/8-D5-AS (Order No. 574028) belongs to the MS4 series modular service unit, specifically a precision pneumatic pressure regulator. It is designed for continuous stabilization of compressed air supply pressure within pneumatic automation circuits. Adopting modular assembly design, it can be combined with filters, lubricators and other MS series components to form an air preparation unit. This model features G1/8 port connection, built-in pressure gauge interface and lockable adjustment knob. Widely used in machine tools, automated assembly lines, packaging machinery and general industrial pneumatic control systems to provide constant operating pressure for cylinders, solenoid valves and actuators. The supplied unit is brand-new original genuine Festo product.
