The AirTAC GFR600C20MF3T AirTAC Filter Regulator 3/4 in NPT is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20MF3T is a GFR-series filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This size 600 unit has 3/4 in NPT ports, a manual-drain bowl in aluminium alloy, a 40 um standard filter element, a square pressure gauge scaled in bar, and a mounting bracket. The standard regulator adjusts from 0.05-0.9 MPa (7-130 psi), max inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR line spans sizes 200 to 600 with ports from 1/8 to 1 in, an optional 5 um (W) element, automatic or differential-pressure drains, G or NPT thread options, and gauge or no-gauge variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.15 - 0.9 MPa (20 - 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 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.

Drops filtered, regulated air to the tool-change and clamp circuits of a CNC machining center at the point of use, with the square bar gauge giving the operator a quick setpoint check.
Feeds a carton-sealing and wrapping line where film grippers and cylinders need steady downstream pressure; the manual drain suits a supervised shift-start bowl check.
Mounted in the services panel of a robotic welding cell to condition air for the weld-gun clamp and tip-dresser circuits before it branches out to the valve manifold.
Choose the size by port and the demand of your circuit: this 600 unit steps up to 3/4 in NPT for higher-flow lines, while 200/300/400 units cover 1/8 to 1/2 in. Drain is the main running choice: manual (this unit) means you bleed collected condensate by hand, while automatic (A) and differential-pressure (blank) drains handle it for you. The 40 um element is standard; specify W for 5 um where downstream valves need finer protection. Gauge scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and bracket are all decodable from the code. Flow is published as curves, not a single rating, so send us your demand figures and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line demand and we will confirm the sizing from the GFR600 datasheet on request.
The M in GFR600C20MF3T sets a manual drain: you bleed collected condensate from the bowl by hand. Automatic (A) and differential-pressure (blank) drains are catalogue options on the same GFR family if you prefer unattended drainage.
