Festo
531129
Service unit combination MSB4-1/8-FRC3:J7M1
The Festo 531129 is an industrial component featuring a Size 4 MS-series design structure comprising a filter regulator with pressure gauge and a proportional standard mist lubricator. It delivers a standard nominal flow rate of 900 l/min across a working pressure of 1.5 to 14 bar and a pressure control range of 0.3 to 7 bar, utilizing a 5 µm grade of filtration and a manual rotary condensate drain. This unit incorporates a rotary knob actuator lock with an integrated lock, a plastic bowl guard, and a controller function providing constant output pressure, initial pressure compensation, secondary exhaust, and return flow for compressed air or inert gases conforming to ISO 8573-1:2010 [-:4:-].

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
