The AirTAC GFR600C20MLC1WT AirTAC Filter Regulator NPT3/4, 5 um 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 GFR600C20MLC1WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and holds downstream pressure at a set point, in a single size-600 body with a 3/4 in NPT port. This configuration carries the fine 5 um filter element (code W), a manual drain bowl, the low-pressure regulator type, and a fitted round pressure gauge scaled in MPa. The 600-size bowl is aluminium alloy, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, manual, automatic or differential-pressure drains, standard or low-pressure regulator types, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 0.15 - 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.

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.

Conditioning the air branch that feeds grippers, capping heads and reject cylinders on a bottling line: the 5 um element protects fine sealing components from particulate and the regulator holds a steady, low set point for gentle handling.
Supplying the pop-up diverters, stoppers and gate cylinders along a conveyor system, where the manual-drain bowl is bled at shift checks and the regulator keeps actuator speeds predictable across the line.
Feeding tool-change clamps, chip doors and air-blast nozzles on a machining centre, with the round MPa gauge giving the operator a visible set point and the 5 um grade guarding the machine's pneumatic valves.
Size 600 with a 3/4 in NPT port is the large-flow step of the GFR range; step up or down through sizes 200/300/400/600 to match the pipe and the air demand of the circuit. This unit is already specified with the 5 um element, manual drain, low-pressure regulator type and a round MPa gauge; if you need the standard 40 um grade, a different drain style, a square embedded gauge, psi or bar scale, G (BSPP) or PT thread, or a no-bracket version, those are decodable options in the same family. Note the low-pressure type is chosen where the working set point sits below the standard regulator's range; the exact adjustment window for this type is not published, so ask us to confirm it against your set point. Because flow is published as curves rather than a single rating, send us your application's air demand and we will confirm sizing 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 for this family as curves, not as a single rated figure, so we do not quote a number here. Tell us your application's air demand and we will confirm the sizing from the datasheet on request before you order.
The M in the code selects a manual drain: the bowl is emptied by hand at service intervals rather than automatically, which suits installations that are checked regularly. The L selects the low-pressure regulator type, intended for set points below the standard type's range; the exact adjustment window for this type is not published, so ask us to confirm it for your set point.
