The AirTAC AirTAC GFR60020MC2WGK Filter Regulator G3/4, 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 PT3/4" 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 GFR600 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This GFR60020MC2WGK is the size 600 unit with a G3/4 threaded port, a 5 um filter element (code W, finer than the 40 um standard), a manual drain on the aluminium alloy bowl, a fitted round gauge with a psi scale, and a reverse/check valve. The standard regulator adjusts from 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options for manual, automatic or differential-pressure drains, 5 um or 40 um filtration, gauge type and scale, G, NPT or PT threads, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing 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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| 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. |
| G | G (BSPP) 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.

Clean, regulated air to spray booths and guns: the 5 um element protects finish quality from water and particulate while the regulator holds a steady gun pressure on a 3/4-inch supply.
Feeding larger pneumatic cylinders and actuators on a packaging conveyor, where the check valve holds downstream pressure if the upstream supply dips and the manual drain is bled at shift checks.
Supplying quarter-turn pneumatic valve actuators on a process skid, with the psi round gauge giving operators a local setpoint readout and the 5 um grade guarding positioner air.
Size 600 with a G3/4 port is the largest step in the GFR range; choose 200/300/400/600 according to the flow your line needs and confirm against the published flow curves before ordering. Drain choices are manual (this unit), automatic, or differential-pressure; manual drain suits installations where an operator can bleed the bowl on a routine basis. Filtration here is 5 um (code W) for finer protection than the 40 um standard. The round gauge is fitted with a psi scale; MPa and bar scales are available, and an embedded square gauge is the standard alternative. The thread is G (BSPP); PT is the standard thread, with G and NPT as order options. A mounting bracket is included and a reverse/check valve is fitted. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing directly from the datasheet before you order.
The manual drain means an operator opens the bowl drain to discharge collected water and contaminants, which suits attended installations with routine checks. If you need unattended removal, the GFR600 is also available with an automatic drain or the differential-pressure drain, and the bowl on size 600 is aluminium alloy.
