About the Airtac BC Series Air Treatment Combination (Filter Regulator Lubricator) BC40004
For PT1/2 supply lines read in mixed units, the BC40004 order code configures AirTAC's largest B-line set - BF4000C filter, BR4000C regulator and BL4000C lubricator - with the dual kgf/cm2 and psi gauge scale that the trailing 4 selects in the ordering table. It is the standard-pressure, standard-element version of the BC4000.
It regulates 0.15 - 0.9 MPa (20 - 130 psi) and accepts a maximum working pressure of 1.0 MPa (145 psi) with 1.5 MPa (215 psi) proof pressure over -5 to +70 C (no freezing). Drain is differential plus manual, the standard B-line arrangement; the filter bowl holds 60 cc and the lubricator 90 cc, using ISO VG32 turbine oil. The GS40 gauge arrives on the dual kgf/cm2 and psi scale.

How to choose
Among the three BC4000 codes listed, BC40004 is the one to order for a PT-thread 1/2 line where the panel is read in kgf/cm2 and psi and the standard 40 um element is sufficient. BC40001W shares the PT thread but carries the 5 um W element and an MPa dial, while BC40003G switches to G thread with a bar gauge. If a PT3/8 port is large enough for the flow, the smaller BC3000 covers the same standard-pressure 0.15 - 0.9 MPa range.
Applications
High-flow valve and tool supply
The 1/2 PT port feeds high-consumption circuits such as large valves and air tools, with the standard 40 um element suiting general shop air.
Conveyor actuation circuits
Cylinder-driven conveying and diverting lines can be conditioned by one 60 cc-bowl set, lubricated with ISO VG32 oil from the 90 cc reservoir.
Mixed-unit commissioning
Teams working from both metric and imperial drawings can set and verify pressure on the kgf/cm2 and psi dial without carrying a conversion table.
FAQ
What are the key figures of the AirTAC BC40004?
BC4000 body with PT1/2 port, built from BF4000C filter, BR4000C regulator and BL4000C lubricator; standard 40 um element; GS40 gauge on a kgf/cm2 and psi scale; drain bowl 60 cc and lubricator 90 cc; regulating range 0.15 - 0.9 MPa (20 - 130 psi); maximum pressure 1.0 MPa (145 psi); proof pressure 1.5 MPa (215 psi); -5 to +70 C; differential plus manual drain.
How is the BC40004 different from the BC40001W?
Both are standard-pressure BC4000 sets on a PT1/2 port with differential plus manual drain, but BC40004 keeps the standard 40 um element and reads the GS40 gauge in kgf/cm2 and psi (trailing digit 4), while BC40001W adds the W option for a 5 um element and uses scale 1, an MPa dial.
