The AirTAC GFR20008MC2WGK 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 AirTAC GFR200 series combines water and particulate filtration with pressure regulation in a single compact body, so one G1/4 unit does the job of a separate filter and regulator. This configuration is the 200 size with a 1/4 in G-thread port, a manual drain bowl in PC (polycarbonate), a fine 5 um filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve. The manual drain means an operator opens the bowl drain to release collected condensate, which suits cabinets and machines that are visited during routine checks. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing), and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of 40 um standard or 5 um (W) filtration, manual, automatic or differential-pressure drains, square or round gauges with MPa, psi or bar scales, and G (BSPP), NPT or PT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the flow and datasheet figures for your application before ordering.

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.

| 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.

On a bench press or clamping fixture fed from a shop air line, this unit filters water and swarf from the supply at 5 um and lets the operator set and read a stable regulated pressure on the psi gauge, with the check valve holding the set pressure if the main supply dips.
On a cartoning or wrapping machine where the air prep station sits inside a cabinet checked on a maintenance round, the manual drain suits supervised equipment, and the 5 um element protects downstream directional valves and cylinders from condensate and fine particulate.
For a lab bench or test rig where instruments and pneumatic actuators need clean, precisely set air, the fine 5 um filtration plus a round psi gauge gives visible, repeatable pressure setting at the point of use, with the included bracket allowing tidy panel or frame mounting.
Start with the port and size step: the 200 size carries a 1/4 in port, and stepping up to 300, 400 or 600 buys more flow capacity at larger ports - match the step to the air demand of the machine rather than the fitting alone. This unit is already specified with the fine 5 um element (the 40 um standard element is the alternative if your application tolerates coarser filtration), a manual drain, and a round psi gauge. If nobody will regularly visit the unit to drain condensate, consider the automatic or differential-pressure drain versions instead. Thread choice is G (BSPP) here, with NPT and PT available to order; a bracket is included, and the reverse/check valve is fitted to hold downstream pressure if the supply drops.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm the flow and datasheet figures against your requirement 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 flow for the GFR family as performance curves rather than a single rated figure, so we do not quote a rated flow number for this unit. Tell us your application and air demand and we will confirm the flow from the datasheet on request, so you can size the 200 unit against the 300, 400 and 600 steps with confidence.
The M in the code means the bowl drain is opened by hand to release collected condensate, which suits machines that are visited during routine maintenance. If the unit will be left unattended or mounted where it cannot easily be reached, choose the automatic drain (code A) or the differential-pressure drain (the default) version instead - the filter grade, gauge and port options stay the same.
