The AirTAC AFR Air Filter Regulator AFR20004W 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 AirTAC AFR20004W is a compact A-line filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the 1/4 in (2000C) size with a standard PT thread, the 5 um (W) filter element for finer particulate removal than the standard 40 um grade, a differential-pressure drain with manual override in the PC bowl, standard pressure regulation of 0.15-0.9 MPa (20-130 psi), and a pressure gauge included with a kgf/cm2 and psi scale. The push-to-lock self-locking adjustment knob holds the set pressure against drift and vibration. This is a genuine AirTAC part from the compact A/B line, built for compressed air only, rated at 1.0 MPa (145 psi) maximum inlet pressure and 0.15-0.9 MPa (20-130 psi) regulation range, with an operating temperature of -5 to 70 C (non-freezing). The A-line also comes in 1/8 in (1500C), 3/8 in (3000C) and 1/2 in (4000C) sizes. Flow figures are not published as a single rating, so we confirm the datasheet numbers for your application 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 A-line when your flow demand and piping suit 1/8 to 1/2 in ports; the larger B-line covers heavier duties - we confirm the matching flow figure from the datasheet before you order. This unit already carries the 5 um element (W); the standard grade is 40 um if finer filtration is not needed. Drain is the differential-pressure type with manual override; an automatic-drain version is available if the unit sits where manual draining is impractical. This is the standard type (regulation up to 0.9 MPa); a low-pressure (L) type limited to 0.4 MPa exists. The gauge is included here with a kgf/cm2 and psi scale; psi, MPa or bar scales, a no-gauge build, and G (BSPP) or NPT threads instead of PT are order options. Because flow is not a single published rating, ask us to confirm sizing against your consumption before ordering.
Feeding clean, regulated air to PLC-driven valve manifolds and pilot circuits on packaging and assembly machines, where the 5 um element helps protect sensitive pilot components and the kgf/cm2/psi gauge supports routine line checks.
Conditioning the shop-air supply to pneumatic tool changers, clamps and air bearings on machining centers, holding a stable set pressure with the self-locking knob while the bowl collects water condensed out of the compressed-air line.
Supplying filtered, pressure-controlled air to bench-top test rigs, pneumatic grippers and sample-handling actuators, where the finer 5 um grade and a readable gauge in kgf/cm2 and psi suit instrument-grade setups.
AirTAC does not publish flow as a single rated figure for the compact A/B line, so we do not quote a number that could mislead your sizing. Tell us your line pressure and air consumption and we will confirm the flow and datasheet figures for the AFR20004W (1/4 in, 5 um element) on request before you order.
The trailing digit is the gauge scale: 4 means the included pressure gauge is marked in kgf/cm2 and psi. Other scales are available - 1 for MPa, 2 for psi, 3 for bar - and an N-suffix version omits the gauge entirely. If you need the gauge with threads on both sides, ask about the D option when ordering.
