The AirTAC BFC F.R.L Pneumatic Air Filter BFC4000AL4 is a genuine A/B-line two-unit F.R.L. set with PT1/2" ports. It is the compact air-preparation line, regulating 0.15 - 0.9 MPa (20 - 130 psi) with a push-to-lock knob and oil-mist lubrication with a transparent sight dome. Flow is confirmed from the datasheet on request.
The BFC4000AL4 is a two-unit AirTAC compact set for 1/2 inch PT ports: a B-line filter-regulator paired with a lubricator, so one assembly filters, regulates and lubricates the compressed air. The filter section runs the standard 40 um element with an automatic drain in its PC bowl, the regulator is the L low-pressure type with output limited to 0.4 MPa and a self-locking push-to-lock knob, and the set includes a gauge on a kgf/cm2 & psi scale. The lubricator has a transparent sight dome so the oil drip rate can be watched and adjusted directly.
This is a genuine AirTAC part from the larger B-line body of the compact A/B series, for compressed air only, with a maximum inlet/working pressure of 1.0 MPa (145 psi) and a temperature of -5 to 70 C (non-freezing). The compact line is also available in 1500 (1/8 inch), 2000 (1/4 inch) and 3000 (3/8 inch) sizes. Flow and other datasheet figures are not published as a single rating, so we confirm them on request.

Specifications follow the official AirTAC A/B-line air-preparation data. Drain type, filter grade, gauge and low-pressure options are set by the model-code suffix - see the description. Flow curves, weight and outline dimensions are not published in our data set — ask us and we confirm from the factory datasheet.
Choose this B-line BFC4000 set when 1/2 inch ports and the larger body suit your demand; the A-line AFC series covers 1/8 to 1/2 inch in the smaller body. Drain: this code carries A for automatic draining, while the default is differential-pressure with manual drain - pick automatic for unattended installations. Filter grade: 40 um standard here; add W to the code for the 5 um element. Regulator: this is the L low-pressure type capped at 0.4 MPa, while the standard type spans 0.15-0.9 MPa (20-130 psi). Gauge scales: 1 MPa, 2 psi, 3 bar, or 4 kgf/cm2 & psi (this model); use N to omit the gauge. Thread: PT is standard, with G and NPT to order. Flow is not a single rating, so ask us to confirm sizing before ordering.
Supplies filtered, regulated and lubricated air to the pneumatic cylinders that index, fill and cap containers, with automatic drainage suiting continuous production.
Feeds impact wrenches and air ratchets at a service bay: the 40 um element blocks water and debris, the regulator sets tool pressure, and the lubricator mists oil for tool life.
Delivers clean, lubricated air at a fixed low pressure to clamping cylinders on machining fixtures, with the sight dome allowing quick oil-feed checks at the machine.
Flow is not published as a single rated figure for this compact series, so we do not quote one. Send us your operating pressure, set pressure and expected air consumption, and we will confirm the flow and the full datasheet for the BFC4000AL4 on request.
The A marks an automatic drain, which expels collected condensate from the PC bowl without operator attention. The default for this family is a differential-pressure drain with manual operation; choose automatic for machines that run unattended.
