The AirTAC GFR20008MF2WGK AirTAC Filter Regulator G1/4, 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 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 GFR20008MF2WGK is an AirTAC GFR200 filter regulator: water and particulate filtration plus downstream pressure regulation in a single body. This configuration carries a G1/4 (BSPP) port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for the PC bowl, an embedded square gauge scaled in psi, a built-in reverse/check valve, and a mounting bracket. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with this manual-drain version, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options across drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT as catalogue options), bracket and check valve. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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 0.05 - 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.

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 filtered, regulated air to a machining centre's pneumatic tool-change and clamping circuits, where the 5 um element and psi-scaled gauge keep the supply clean and set to the machine's specified pressure.
Conditioning the air feeding cylinders and grippers on a packaging conveyor, with the check valve holding the downstream circuit if upstream pressure is interrupted and the manual drain cleared during shift checks.
Supplying cleaner, regulated air to spray equipment at a fabrication plant, where the 5 um grade reduces particulate carryover and the square psi gauge lets operators verify set pressure at a glance.
Start with the port step: this unit is the 200 size at 1/4 inch; step up to GFR300/400/600 if the line needs a larger port and more flow. The 5 um element here suits air that must be cleaner than the 40 um standard grade; both grades are available across the family. Drain choice matters: manual drain (this unit) needs periodic bowl draining, while automatic and differential-pressure drains discharge condensate without operator action. Gauge scale is selectable (MPa, psi or bar) with an embedded square gauge standard and an external round gauge optional. Thread is PT as standard, with G (BSPP, as on this model) and NPT as order options; a bracket is included, and a reverse/check valve can be fitted as here.
Flow for the GFR series is published as curves, not a single rated figure, 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.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure, set pressure and demand, and we will confirm the datasheet curve and check the sizing for your application on request.
The M in the code selects the manual drain: condensate collects in the PC bowl and is released by opening the drain fitting, so it needs periodic attention. Automatic and differential-pressure drain versions of the same GFR200 filter regulator are available if you would rather not rely on operator draining.
