Why off-line filters? Experience shows off-line filtration has very effective results for many applications in fluid power and lubrication systems. Independent from pressure ripples and flow surges, off-line filters develop the best possible retention of particulates and offer the highest possible dirt holding capacity. In combination with other system components, eg. coolers or heaters, installation cost and space requirements can be minimized. Why Bühler? The Fluidcontrol division of Bühler has focused on the fluid power and lubrication industries for a long time and has developed an intimate...

optional port G1/4 manometer or pressure indicator optional port G1/4 manometer or pressure indicator Planning hints Installation Location When mounting the BNF outdoors adequate weather protection is necessary. Leave access for servicing. Mounting BNFs are mounted with four bolts. The strength of the base must be strong enough to carry the unit. Tubing Tubing to the system has to be free of tension and vibration. This will be maintained by using flexible hoses. Take care of local laws concerning environment protection due to accidental leakage (for example, by using drip pans). We reserve the...
