The AirTAC GFR200-08 AirTAC Filter Regulator NPT1/4 Round Bar Gauge is a genuine G-series filter regulator: water separation, 40 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. This unit is the 200 size with a 1/4 in NPT port, standard 40 um filtration, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the bowl is high enough. The fitted round gauge reads outlet pressure in bar, and the built-in reverse/check valve holds the downstream setting if upstream supply is interrupted. Supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans 200, 300, 400 and 600 sizes with port options from 1/8 in to 1 in, PT, G and NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, and MPa, psi or bar gauge scales. Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet 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.

|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| (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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Feeds clean, regulated air to the tool-clamp and chip-blow-off circuits of a CNC machining centre, with the check valve holding the clamp setting during a supply dip.
Conditions the air feeding the cylinders on a carton-forming and sealing line, where the 40 um element protects valve spools and the bar gauge lets operators verify set pressure at a glance.
Serves as the point-of-use filter regulator at a spray booth, dropping line pressure to the gun supply while the differential-pressure drain keeps condensate out of the air stream.
Size and port step up together in the GFR range: 200 through 600, with ports from 1/8 in to 1 in, so pick the size whose flow curve covers your demand rather than guessing from a single number. This unit uses the standard 40 um element; specify the W suffix if your application needs 5 um. Drain options are differential-pressure (as fitted here, self-bleeding), automatic, or manual (a manual drain widens the regulation range to 0.05-0.9 MPa). Gauge scale is selectable as MPa, psi or bar; this unit carries a round bar gauge. Thread is PT as standard with G and NPT available to order, and a bracket can be added if you did not order the J (no bracket) version. Because flow is published as curves and not as a single rated figure, 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet flow figures for this unit on request before you order.
K means a reverse/check valve is fitted, so the downstream pressure setting is held if the upstream supply drops. This unit also carries the differential-pressure drain (blank position in the code), which automatically expels collected condensate when the pressure differential across the bowl is sufficient - no daily manual draining needed.
