Why off-lin filtrs? Exprinc shows off-lin filtration has vry ffctiv rsults for many applications in fluid powr and lubrication systms. Indpndnt from prssur rippls and flow surgs, off-lin filtrs dvlop th bst possibl rtntion of particls and offr th highst possibl dirt holding capacity. In combination with othr systm componnts, g. coolrs or hatrs, installation cost and spac rquirmnts can b minimizd. Why Bühlr? Th Fluidcontrol division of Bühlr has focusd on th fluid powr and lubrication industris for a long tim and has dvlopd an intimat undrstanding of th rquirmnts for ths applications. Although not a filtr manufacturr in th classical sns, w contribut som advancd dvlopmnts to off-lin filtr units for th bnfit of this markt. Th filtr housing can accommodat filtr lmnts according to DIN 455 availabl from major filtr supplirs world wid. If you do not find an adquat solution for your application in this litratur plas do not hsitat to contact us for a spcific application proposal. Dscription BKF 18/3 This unit offrs a vry compact dsign with an intgratd low-nois, dirt-rpllant grotor pump. Placmnt of motor and filtr lmnt rsult in minimal installation spac. Suction and prssur hos ar installd dirctly downwards into th rsrvoir. This minimizs installation work. As th basic fram provids additional connctions at th front, th unit may b installd on th sid of th rsrvoir. Th unit contains a limiting valv and filtr lmnts of siz DIN NG 5. BKF 6/9 Du to th largr pump and filtr housing this unit is assmbld on a ruggd fram for vrtical attachmnt. This unit offrs th sam principal dtails as th BKF 18/3 but dos not hav an intgratd by-pass valv in th pump. If closly coupld to th filtr unit, th complt coolr installation rquirs just a littl mor spac than th filtr unit. Th hat dissipation can b as high as 6 hp. DE 38 1/14 Pag /6
