The AirTAC GFR20008C2W AirTAC Filter Regulator PT1/4, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/4" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR20008C2W is a filter regulator in one body: it removes water and particulate from compressed air and regulates downstream pressure in the same compact unit. This configuration is the 200 size with a PT1/4 (1/4 in) PT thread, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough, and an external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing). The polycarbonate bowl suits this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, a choice of 40 um standard or 5 um (W) filter grade, differential-pressure, automatic or manual drains, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds the clamping and tool-change circuits of a CNC machining centre with clean, regulated air; the 5 um element helps protect tight-tolerance valves and cylinders on the fixture line.
Sits at the air inlet of a cartoning or wrapping machine, filtering water and particles out of the supply and holding a steady regulated pressure for the sealing and forming actuators.
Conditions the compressed air feeding bench-top lab equipment and analytical instruments, where the finer 5 um grade and a stable regulated pressure protect sensitive pneumatic controls.
Start with the size and port: the 200 series with PT1/4 suits lines built around 1/4 in air supply; step up to 300, 400 or 600 if the circuit demands larger ports. Choose the drain to match maintenance practice: this unit's differential-pressure drain works unattended, while automatic (A) and manual (M) versions are catalogue options. The 5 um element fitted here is the finer grade for air that feeds sensitive components; the 40 um standard grade is the alternative. The round psi gauge fitted here is one of the gauge options (embedded square gauge standard, external round gauge optional, in MPa, psi or bar scales), and PT is the standard thread with G (BSPP) and NPT available to order. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
The W in the code GFR20008C2W selects the optional 5 um filter grade; the catalogue default is 40 um. The 5 um element is chosen when downstream equipment is sensitive to finer particles. Both grades are available across the GFR sizes, and the differential-pressure drain on this unit removes collected condensate automatically.
