The AirTAC GFR200-08 AirTAC Filter Regulator G1/4, 5 um, psi 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: one body that removes water and particulate from compressed air and holds downstream pressure steady. This unit is built on the GFR200 size with a G1/4 (BSPP) port, a 5 um filter element, a polycarbonate bowl with a differential-pressure drain, and a round pressure gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). It is supplied without a mounting bracket and without a reverse-flow check valve.
This is a genuine AirTAC part from the G-series air-treatment line. GFR filter regulators are published in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and can be ordered with manual or automatic drains, a 40 um standard or 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, G or NPT thread options, and with or without a bracket. Flow is published as curves rather than a single rating, so ask us to 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.

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

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.

Feeding clean, pressure-stabilised air to pneumatic clamps and tool-change cylinders on a machining centre, where the 5 um element protects close-tolerance valve spools from particulate carryover.
Conditioning the air that drives pusher and divert cylinders sorting cartons on a bottling or packaging conveyor, keeping the regulator setting steady as line demand fluctuates through the shift.
Installed at the air drop feeding an assembly station's impact drivers and air presses, removing condensed water from the header supply and giving each station its own set working pressure.
Choose the GFR200 size when your line ports at 1/4 in and your flow demand sits within this frame; the larger 300, 400 and 600 sizes carry bigger ports and more flow. This unit is already configured with the 5 um element - the 40 um standard element is the catalogue alternative if finer filtration is not required - plus a differential-pressure drain and a round psi gauge; embedded square gauges and MPa or bar scales are the other gauge choices. The thread here is G (BSPP); PT is the standard thread and NPT is also available to order, and a mounting bracket can be added if panel mounting is needed. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 rather than a single rated figure, so there is no one number we can quote honestly. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The code carries a W, which selects the 5 um element; without that letter, GFR units come with the 40 um standard element. The 5 um grade suits applications that need finer particulate removal ahead of sensitive pneumatic components, while 40 um covers general plant air. Both grades are catalogue options, so you can order the other if your application calls for it.
