About the Airtac BC Series Air Treatment Combination (Filter Regulator Lubricator) BC2000A4
AirTAC builds the BC2000A4 around the BF2000C filter, BR2000C regulator and BL2000C lubricator, a B-line three-unit set sized for PT1/4 ports. The A in the order code selects the automatic drain, a drain option reserved for the B-line, while the trailing digit 4 fits a gauge scaled in kgf/cm2 and psi.
The standard regulator covers 0.15 to 0.9 MPa (20 - 130 psi) with a 1.0 MPa maximum and 1.5 MPa proof pressure. The 40 cc drain bowl and 60 cc lubricator reservoir set the service intervals, and the standard 40 um element screens coarse contamination before air reaches valves and cylinders.

How to choose
Choose BC2000A4 when you want the full 0.9 MPa range plus hands-off condensate removal. Its siblings in the ordering table trade one of those away: BC2000AL1 and BC2000L1 are the low-pressure (L) versions capped at 0.4 MPa, and a code ending in 1 puts the gauge in MPa instead of the kgf/cm2 and psi scale. Leaving out the A gives a differential plus manual drain.
Applications
Machine point-of-use air supply
A PT1/4 three-unit set feeding a single machine or cell, with the 40 um element and lubricator protecting cylinders and valves downstream of the BR2000C regulator.
Unattended conveyor and packing lines
The A automatic drain empties the 40 cc filter bowl without a walk-round, so remote line sections stay drained between maintenance visits.
Plants reading gauges in psi
The digit 4 gauge shows kgf/cm2 and psi, suiting teams that set the 0.15 to 0.9 MPa range (20 - 130 psi) against psi markings.
FAQ
What are the key figures of the AirTAC BC2000A4?
PT1/4 ports; BF2000C filter with 40 um element, BR2000C regulator, BL2000C lubricator; regulating range 0.15 to 0.9 MPa (20 - 130 psi); 1.0 MPa maximum pressure, 1.5 MPa proof pressure; automatic drain with 40 cc bowl; 60 cc lubricator capacity; gauge in kgf/cm2 and psi; -5 to +70 C operation with no freezing.
How does the automatic drain option work here?
The A option makes the filter bowl discharge condensate automatically. On B-line codes without A the drain is differential plus manual, so the 40 cc bowl must be emptied by hand. AirTAC recommends ISO VG32 turbine oil for the 60 cc lubricator reservoir.
