4 4/10 Bosch Rexroth AG Hydraulics ELF, BF, BL RE 50070/10.05 Function, symbol, section The reservoir oil filler/breathers, type ELF basically comprises of an air filter for filtering the air flowing into the reservoir and a filler sieve for retaining coarse dirt particles while filling. The reservoir breathers, types BF and BL are, however only air filters. Symbol With clogging indicator version "K" (only build size 7) Reservoir filler/breather type ELF Reservoir filler/breathers, type ELF are combined air filters for filtering air flowing into the fluid reservoir and filler sieves for retaining coarse dirt particles when filling. The large sieve area allows the pressure fluid to be rapidly filled. Types ELFP 3... and ELFP 4... These basically comprise of filter cap (1), air filter element (2), filler sieve (3) and security chain (4). Air enters via holes (5) on the underside of filter cap (1). In this way, only particles suspended in air may enter the air filter element (2), where they are separated according to the filter rating. Type ELFP Type ELFP 5... These basically comprise of an air filter housing (cover 1.1; lower component 1.2), air filter element (2) and filler sieve which is screwed onto the air filter (3). Air enters via the ring gap (5) between cover 1.1 and the lower component 1.2. In this way, only particles suspended in air may enter the air filter element (2), where they are separated according to the filter rating. They are fitted with replaceable air filter elements (2). Type ELFP Type ELFP 7... These basically comprise of an air filter housing (cover 1.1, lower component 1.2), air filter element (2) and filler sieve (3). Cover (1.1) and the lower component (1.2) are made of glass fibre reinforced plastic and connected to each other via threads. Air enters via openings (5) on the sides of lower component (1.2). In this way, only particles suspended in air may enter the air filter element (2), where they are separated according to the filter rating. They are fitted with replaceable air filter elements (2). For the monitoring of element contamination, the filters are available with a pressure gauge (6). Type ELFP 7...K

5 RE 50070/10.05 ELF, BF, BL Hydraulics Bosch Rexroth AG 5/10 Function, symbol, section Reservoir breathers BF and BL Reservoir breathers, type BF are only designed as air filters and are screwed directly onto the reservoir. In principle, the function of these filters is the same as the ELF filler/breather. The difference is in that the filling sieve is not included. Build sizes 5 and 7 are equipped with replaceable air filter elements. Type BL breathers comprise of a mounting stud (6) which is fitted onto the reservoir and a filter cartridge (2). The filter cartridge screws onto the stud. 2 6 Type BFP 7...K... Type BLP 162 S... Characteristic curves (air flow in standard litres per minute.

Selection criteria We recommend that the air filter (with clean element) is selected using the filter selection diagram. Start-up - p = 0,01 bar Filter ELF and BF p = 0,01 bar ELFP 4/BFP 4 ELFP 3/BFP 3 ELFP 7/BFP 7 ELFP 5/ BFP 5 10 Filter selection diagram, example The filter selection diagrams are valid for the air filter types ELF and BF, build sizes 3, 4, 5, 7 and types BLP 162 S and BLP 162 F. The filter sizes are determined with the help of the selection diagrams, using a pressure differential of 0,01 bar. The following example explains the method of using the filter selection diagrams: Example: Air flow Q l (in standard litres per minute): 300 l N /min Filter type: ELF-Filter Recommended start-up- p : 0.01 bar Determination of the build size for Q l = 300 l/min using the filter selection diagram: Build size 3 Filter type: ELFP Filter BLP 162 p = 0,01 bar BLP 162
