The AirTAC BFR Air Filter Regulator BFR4000L4W 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 BFR4000L4W is a compact B-line filter regulator: one body that removes water and particulate from compressed air and then regulates the downstream pressure. It does not lubricate the air. This configuration is the 1/2 in port size with PT threads (the AirTAC standard), the low-pressure type with regulation up to 0.4 MPa, the 5 um W filter element instead of the 40 um standard, a drain bowl with differential-pressure and manual draining, and an included gauge with a dual kgf/cm2 and psi scale.
This is a genuine AirTAC part from the compact A/B line, not the larger G/GA range. The bowl is polycarbonate and the push-to-lock knob keeps your set pressure from drifting; maximum inlet pressure is 1.0 MPa (145 psi). The compact range also covers 1/8, 1/4 and 3/8 in ports, with G and NPT threads to order. AirTAC does not publish flow as a single rated figure, so we confirm datasheet flow and sizing figures for you 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 the B-line 4000 body for 1/2 in piping; the A-line serves the same port in a smaller body, and 1/8, 1/4 and 3/8 in sizes complete the compact range. The L marks the low-pressure type, limited to 0.4 MPa - if your circuit needs up to 0.9 MPa, take the standard type instead. The W selects the 5 um element; the blank code carries the 40 um standard grade. Draining here is differential-pressure with a manual option; the A variant gives an automatic drain. The trailing 4 means the included gauge reads kgf/cm2 and psi. This code uses PT thread; order G or NPT if your piping needs them.
Flow is not stated as one rated number for this family, so send us your operating conditions and we will confirm datasheet sizing before you order.
Conditions and regulates the low-pressure air that loads pneumatic rollers and thread guides on a textile line, with the 5 um element keeping moisture and lint-borne dirt out of the actuators.
Feeds cleaned, regulated low-pressure air to the diverter and pusher actuators on a parcel sorter, holding a gentle set pressure that will not slam light packages.
Provides filtered, low-pressure pilot air to pneumatically actuated process valves on a plant skid, where a stable, contaminant-free pilot signal keeps valve positioning reliable.
AirTAC does not publish a single rated flow figure for this family, so we will not quote one without backing. Share your inlet pressure, set pressure and air consumption, and we will confirm the flow and sizing figures from the datasheet on request.
It is the gauge scale: the pressure gauge supplied with this filter regulator reads in kgf/cm2 and psi on a dual scale. The gauge is included by default; only the N variant of the code omits it, and other scale options (MPa, psi or bar) are available in the other code variants.
