The AirTAC BFR Air Filter Regulator BFR4000A1 is a genuine A/B-line filter regulator 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. Flow is confirmed from the datasheet on request.
The AirTAC BFR4000A1 is a compact B-line filter regulator combining water and particulate removal with pressure regulation in one body, sized at the 1/2 in port on PT threads. This configuration carries the 40 um standard filtration element, an automatic drain that discharges condensate from the PC bowl without operator attention, the standard pressure type, and an included gauge with an MPa scale. Regulation range is 0.15 to 0.9 MPa (20 to 130 psi) with a maximum working pressure of 1.0 MPa (145 psi), and the push-to-lock adjustment knob prevents the setpoint from drifting.
This is a genuine AirTAC part from the compact A/B line, not the larger G/GA series. The same function is offered in the smaller A-line (AFR) and across 1/8 in, 1/4 in, 3/8 in and 1/2 in ports, with G (BSPP) or NPT threads available to order against the PT standard. Flow is not published as a single rated figure, so ask us to confirm the datasheet flow numbers for your sizing before ordering.

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.
Use this 1/2 in B-line body where flow demand is high, such as cell-level air supplies, and step to the A-line AFR or smaller ports for point-of-use duty. The automatic drain in this code is the right choice for unattended or hard-to-reach installations; choose the default differential-pressure plus manual drain only where someone checks the bowl routinely. The 40 um element suits general plant air, while a W-suffix code gives the 5 um element for cleaner circuits. The gauge reads in MPa; other scale options and a no-gauge version exist in the family, and PT is the standard thread with G or NPT to order. Flow is not a single published rating, so have us confirm datasheet figures against your demand before you order.
Installed on a 1/2 in drop serving a remote production area from the compressor room, the automatic drain keeps condensate out of the line where no operator passes, and the regulator pins a stable pressure for the whole area.
Mounted at the air inlet of a robotic assembly cell, it filters and regulates the supply feeding grippers, clamps and pneumatic actuators, with the MPa gauge giving maintenance a reference setpoint after changeovers.
Placed ahead of a pneumatic punching or forming press, it delivers clean, moisture-dropped air at the regulated pressure the press cylinder circuit requires, draining condensate automatically between cycles.
AirTAC does not publish flow for this compact B-line filter regulator as a single rated figure, and we will not estimate one. Share your required flow and working pressure and we will confirm the datasheet flow figures for the BFR4000 size so you can size the unit with confidence before ordering.
The A in this code means the PC bowl drains collected condensate automatically, without anyone opening or watching it. That makes this version the better pick for unattended cells, elevated or enclosed mounts, and locations checked only during maintenance rounds. Where an operator is present regularly, the default differential-pressure plus manual drain code is the economical choice.
