The AirTAC GFR200-08 NPT1/4 AirTAC Filter Regulator, 5 um, Manual Drain 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 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 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This unit is the 200 size with a 1/4 in NPT port, a 5 um filter element (W grade), a manual drain bowl in polycarbonate, an embedded square gauge scaled in MPa, and a reverse/check valve fitted. A mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and with the manual drain the regulation range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for automatic, manual or differential-pressure drains, 40 um standard or 5 um elements, gauge scales in MPa, psi or bar, and G, NPT or PT threads. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures for your application.

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 0.05 - 0.9 MPa (7 - 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.
| GFR200 | G-series filter regulator, 200 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 06 = PT1/8", 08 = PT1/4". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeding clean, regulated air to a machining centre's tool-change cylinders and pneumatic clamps, with the 5 um element protecting directional valves from fine particulate.
Holding a steady setpoint on the clamp-cylinder circuit of a welding fixture, with the fitted reverse valve in the line and the manual drain opened at the end of each shift.
Supplying regulated air to pick-and-place cylinders and product diverters on a packaging conveyor, where the operator drains the bowl during routine checks.
Step through sizes 200, 300, 400 and 600 to match the port and flow your line needs; this 200 size takes a 1/4 in NPT port. Drain choice matters: manual drain (this unit) suits attended installations and widens the regulation range to 0.05-0.9 MPa (7-130 psi), while automatic or differential-pressure drains suit unattended duty with a 0.15-0.9 MPa (20-130 psi) range. Choose the 40 um standard element or the 5 um W grade fitted here for finer protection, pick the gauge scale (MPa, psi or bar), and order G or NPT thread variants where PT is the standard. A bracket is included on this size. 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for the GFR series is published as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow curves and correct sizing before you order.
This unit carries drain code M: collected water is removed by opening the drain at the bowl, which suits attended installations. If the unit will run unattended, order the automatic (A) or differential-pressure (blank) drain version - note that with those drains the regulation range starts at 0.15 MPa (20 psi) instead of 0.05 MPa (7 psi).
