The AirTAC GFR200-08 AirTAC Filter Regulator, NPT1/4, 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 GFR200-08 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the 200 size with a 1/4 in NPT port, a 5 um filter element (the finer of the two available grades), a differential-pressure drain that bleeds collected condensate as air flows through, a round pressure gauge reading in bar, and a built-in reverse (check) valve. No mounting bracket is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the set pressure range with this drain type is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing. The bowl on this size is polycarbonate (PC).
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of PT, G or NPT thread, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge or no-gauge builds, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Clean, regulated air for the cylinders and actuators on a cartoning or wrapping line, with the 5 um element protecting sealing and clamping circuits from water and fine debris.
A filtered, regulated air feed for lab automation and analytical equipment, where the finer 5 um grade and the bar-scale round gauge suit precision benchtop setups.
Regulated air for conveyor gate and diverter cylinders, with the built-in check valve holding the downstream circuit if upstream supply is interrupted.
Size and port step up with flow demand: 200 is the smallest GFR size, here with a 1/4 in NPT port (PT is the standard thread; G and NPT are order options). Choose the drain type - differential-pressure (this unit), automatic, or manual - noting the regulation range differs: 0.15-0.9 MPa (20-130 psi) with the auto or differential drain versus 0.05-0.9 MPa (7-130 psi) with manual. Filter grade is 40 um standard or 5 um (code W), as fitted here. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales; this unit carries a round bar gauge. The reverse/check valve (K) and the bracket option complete the build. Because flow is published as curves and not 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
K is the catalogue code for a fitted reverse (check) valve; without it the code simply ends at the thread letter. The W in the code is the 5 um filter grade, the finer option over the 40 um standard - choose 5 um where downstream equipment needs cleaner air, and 40 um where general protection is enough.
