About the Airtac BC Series Air Treatment Combination (Filter Regulator Lubricator) BC20004
The BC20004 is AirTAC's B-line three-unit FRL set - BF2000C filter, BR2000C regulator and BL2000C lubricator - built on PT1/4 ports with the standard differential drain plus manual override and a gauge scaled in kgf/cm2 and psi. The 40 um standard element handles typical compressor carryover, while the 40 cc drain bowl and 60 cc lubricator reservoir give the BC2000 size more reserve than the A-line.
Regulation spans 0.15 to 0.9 MPa (20 to 130 psi) with a 1.0 MPa (145 psi) maximum and 1.5 MPa (215 psi) proof pressure, and the set operates from -5 to +70 C with no freezing. Top the 60 cc lubricator up with ISO VG32 turbine oil to keep downstream valves and cylinders running well.

How to choose
This code keeps the standard differential-plus-manual drain of the BC2000 size; if condensate builds up faster than shift checks allow, step to BC2000A1 or BC2000A1W, which add the A automatic drain. Against the AC2000 on the same PT1/4 port, this B-line set moves more air with the larger 40 cc and 60 cc reservoirs. PT-thread units are ordered with gauge scale 1 (MPa) or 4 (kgf/cm2 and psi), so the trailing 4 fixes the dual-scale dial you receive; larger BC3000 (PT3/8) and BC4000 (PT1/2) sets serve heavier flow.
Applications
Press and clamp circuits
PT1/4 supply drops feeding cylinders, where operators read the kgf/cm2 and psi dual-scale dial and tip the manual drain during breaks.
Conveyor actuator lines
A 40 um element ahead of the BR2000C regulator protects directional valves on 1/4-in conveyor drives running at up to 0.9 MPa set pressure.
Workshop point-of-use air
A compact wall-mounted FRL for benches and air tools, with the 60 cc lubricator metering ISO VG32 oil into tool air.
FAQ
What are the key figures of the AirTAC BC20004?
BC2000-size three-unit FRL on PT1/4: BF2000C filter with 40 um element, BR2000C regulator, BL2000C lubricator. Drain is differential plus manual, bowl 40 cc, lubricator 60 cc. Gauge is kgf/cm2 and psi (scale 4). Regulating range 0.15 to 0.9 MPa (20 to 130 psi), max 1.0 MPa (145 psi), proof 1.5 MPa (215 psi), -5 to +70 C, air only.
Does the BC20004 drain the bowl by itself?
No. With the drain position left blank the unit is differential plus manual, so condensate is drained by hand. Order BC2000A1 or BC2000A1W instead if you need the A automatic drain; confirm fitting details from the datasheet.
