Festo
531551
Filter MS6N-LF-3/8-EUV
The Festo part number 531551 is an MS series industrial component in size 6 featuring a sinter filter with a centrifugal separator, a 40 µm pore size, and a 75% condensate separation degree. Operating within a pressure range of 2 bar to 12 bar, this unit achieves a normal nominal flow rate of 3800 l/min and incorporates a fully automatic and manual, non-detenting condensate drain housed within an integrated metal bowl guard. Designed for vertical ±5° mounting with a product weight of 820 g, it processes compressed air as per ISO 8573-1:2010 [7:9:-] or inert gases under moderate corrosion stress (CRC 2) and temperatures from -10 °C to 60 °C.

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.
