The AirTAC BFR Air Filter Regulator BFR3000ML4 is a genuine A/B-line filter regulator with PT3/8" 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 BFR3000ML4 is a combined filter-regulator in the low-pressure L type: the 40 um standard element removes water and particulate, and the regulator is specified for a maximum setting of 0.4 MPa. The M suffix selects the manual drain, so the PC bowl is emptied by an operator on a set routine, and the 4 suffix orders the gauge with a kgf/cm2 and psi scale. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C, non-freezing, and the medium is compressed air only. The push-to-lock self-locking knob holds the set pressure, and as a B-line unit the bowl sits behind a high-strength plastic protective cover.
This is a genuine AirTAC part from the compact A/B line in the 3000 (3/8 in) size on PT, the family's standard thread, with G (BSPP) and NPT available to order. Other sizes are 1500 (1/8 in), 2000 (1/4 in) and 4000 (1/2 in). Flow and full datasheet figures are not published as a single rating; 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.
Pick the low-pressure L type on this 3000 B-line body when your actuator or process must not see more than 0.4 MPa of regulated pressure; the standard type covers the 0.15 to 0.9 MPa (20-130 psi) range. The 3/8 in PT ports suit mid-range circuits; drop to 1500 or 2000 for lighter duty or move to the 4000 body for heavier demand. Drain choice here is the M-suffix manual drain; the blank position gives the default differential-pressure plus manual drain and A gives the automatic drain. Filtration is the standard 40 um element, with the W suffix offering the optional 5 um grade. This model includes a kgf/cm2 and psi scale gauge; other scale digits select MPa, psi or bar, and N leaves the gauge out. Flow is not a single published rating, so send us your requirement and we will confirm sizing from the datasheet before you order.
Feeding the low-pressure pneumatic pushers and gates along a packaging conveyor, the unit delivers filtered air held safely below the 0.4 MPa ceiling the line's actuators are specified for.
Installed on the air supply of weaving and spinning equipment, the filter-regulator keeps moisture and lint-clogging particulate out while regulating at the gentle pressures delicate yarn handling needs.
Mounted ahead of low-pressure diaphragm valve actuators on a process skid, the unit provides clean air and a locked regulated setting so valve stroke forces stay within actuator limits.
AirTAC does not publish flow for this filter-regulator as a single rated number, so we will not quote one. Share your flow demand in l/min or SCFM and we will confirm the right size and the relevant datasheet figures on request before you order.
The L suffix in BFR3000ML4 selects the low-pressure L type, which is specified for a maximum regulated pressure of 0.4 MPa instead of the standard type's 0.15 to 0.9 MPa (20-130 psi) range. Choose it wherever the downstream equipment must not see higher settings.
