The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 5 um Round Gauge 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body, so one component does both jobs in the air-preparation stage. This unit is the size 200 frame with a 1/4 in NPT port, fitted with the fine 5 um filter element (code W) for applications that need cleaner air than the standard 40 um grade, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, and an external round gauge on a psi scale so operators can read and set line pressure at a glance. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the polycarbonate bowl suits the -5 to 70 C non-freezing operating range.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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.

On a machine frame with air-actuated clamps, this unit filters incoming compressed air to 5 um and holds a steady regulated pressure to the clamp cylinders, with the round psi gauge letting the setter dial in the clamping force.
Feeding valves and actuators on a carton-sealing or wrapping line, the filter regulator protects downstream components from water and fine particles while keeping working pressure stable through each machine cycle.
On a leak-test or pneumatic test bench, the 5 um element and differential-pressure drain deliver clean, dry air to sensitive gauges and transducers, and the psi-scaled gauge gives the operator a direct pressure reference.
Start with the port and size: this GFR200-08 gives you a 1/4 in NPT connection on the size 200 frame, the smallest step in the range - step up to GFR300/400/600 if your line needs larger ports and more flow. This unit already carries the 5 um fine element; choose the standard 40 um grade (no W code) if coarse protection is enough, and keep 5 um where downstream valves or instruments demand cleaner air. The differential-pressure drain here is the fit-and-forget choice; pick automatic (A) for unattended condensate removal or manual (M) where you want operator-controlled draining.
Gauge and thread round out the decode: this configuration has an external round gauge on a psi scale (square embedded gauges and MPa/bar scales are alternatives), NPT threads for US piping, and the mounting bracket is included. Regulation is the standard type, 0.15-0.9 MPa (20-130 psi), with a maximum inlet of 1.0 MPa (145 psi). Flow is published as curves, not a single rating, so 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 figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm against the datasheet curves whether the size 200, 1/4 in port unit is correctly sized before you order.
In the code GFR20008C2WT, the W selects the fine 5 um filter element instead of the standard 40 um grade, and C2 specifies the external round gauge on a psi scale. The differential-pressure drain and mounting bracket are the defaults for this family, and NPT is the thread option selected in place of the standard PT.
