The AirTAC BFR Air Filter Regulator BFR2000M4 is a genuine A/B-line filter regulator with PT1/4" 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 BFR2000M4 is a compact B-line filter-regulator providing 40 um standard-grade filtration and pressure regulation in one body at the 1/4 in PT port size. The M suffix specifies a manual drain, so an operator opens the drain at the PC bowl to remove accumulated condensate, which suits attended stations and sheltered installations. The included kgf/cm2 & psi dual-scale gauge and push-to-lock self-locking knob hold the downstream set pressure across the 0.15-0.9 MPa (20-130 psi) range, with a maximum working pressure of 1.0 MPa (145 psi) on compressed air.
This is a genuine AirTAC part from the compact A/B line, in the 2000 (1/4 in) size with PT as the standard thread; G (BSPP) and NPT are order options. The family also spans 1/8, 3/8 and 1/2 in ports. We do not quote flow as a single rated figure; ask us and we will confirm flow and datasheet figures for this model on request.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.
Select the 2000 (1/4 in PT) size for quarter-inch lines; move to A-line or larger B-line sizes if your port or flow band differs. The M manual drain is the explicit choice over the default differential-pressure drain - pick it where an operator is present to drain the bowl, and the A automatic drain where the unit is unattended. The standard 40 um element is fitted here; choose the W option only if you need 5 um fine filtration. The gauge is included with kgf/cm2 & psi scale; other scales are available in the family.
Flow is not a single published rating for this family, so share your line conditions and we will confirm datasheet sizing before you order.
Installed at the wall drop feeding impact wrenches and ratchets at a maintenance bench, the 40 um element and regulator deliver conditioned air, and the manual drain is emptied as part of the operator's end-of-shift routine.
Used on a service bay rig supplying shop air to commercial-vehicle pneumatic test points, the kgf/cm2 & psi gauge matches the vehicle-side units and the regulator sets steady test pressures with the self-locking knob.
Mounted above a small assembly bench feeding screwdrivers and air cylinders, the compact B-line body keeps the point-of-use supply filtered and regulated, with manual bowl draining handled by the bench operator.
This family is not published with a single rated flow number, so we cannot state one here. The datasheet gives pressure-drop and flow characteristics instead; send us your supply pressure and air demand and we will confirm the datasheet flow data for the BFR2000M4 on request.
The M suffix specifies a manual drain: the operator opens the drain at the PC bowl to expel collected condensate. The default configuration uses a differential-pressure drain that discharges automatically during operation plus a manual drain. Choose manual for attended stations, automatic for unattended or hard-to-reach points.
