The AirTAC GFR200-08 AirTAC Filter Regulator 1/4 PT 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 GFR200-08 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This 200-size unit is threaded PT 1/4 in, carries the finer 5 um filter element (the W grade, against the 40 um standard), a manual drain on the polycarbonate bowl, and a round pressure gauge reading in psi. A reverse/check valve is fitted and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi), the regulated output is adjustable from 0.05 to 0.9 MPa (7 to 130 psi), and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT as standard and G or NPT to order, plus drain, filter-grade, gauge and check-valve choices across the range. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

|---|---|
| 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). |
| 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. |

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.

Filtered, regulated air to pneumatic clamping fixtures on a machining centre - the 5 um element protects the clamp valves while the regulator holds set pressure through the cycle.
Supply for gripper and pusher cylinders on a cartoning conveyor, with the manual drain emptied at shift checks and the check valve holding downstream pressure if the main air drops.
Point-of-use prep for filler and capper actuator circuits, dropping header pressure to a stable working set at the machine instead of relying on the main line regulator alone.
Size the GFR by port and flow: 200 is the compact step at 1/4 in PT; if your demand sits near the top of the 200 flow curve, step up to GFR300 at 3/8 in. This unit has a manual drain - the right choice where an operator is on site for routine checks; automatic or differential-pressure drains suit unattended installs. The 5 um W element is the call ahead of precision valves and cylinders; 40 um is the standard grade. The round psi gauge is fitted here; the embedded square gauge and MPa or bar scales are the alternatives. G and NPT threads are order options against the PT standard, and the bracket is included. Because flow is published as curves, not a single rating, send us your demand and we will confirm sizing against the application before you order.
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, not a single rated number, so we do not quote a figure here. Send us your air demand and line pressure and we will confirm from the datasheet whether the 200 size at 1/4 in PT suits your application.
This unit drains the bowl by hand, which suits installations with an operator on site doing routine checks. If the unit is mounted out of reach or runs unattended, ask us about the automatic or differential-pressure drain versions of the same GFR200-08 configuration.
