The AirTAC AirTAC GFR600C20MLJC1WT 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 GFR600C20MLJC1WT is an AirTAC GFR-series filter regulator: water and particle filtration plus pressure regulation in a single body. This size-600 unit has a 3/4 in NPT port, a 5 um filter element (code W), a manual drain and an aluminium alloy bowl. It is the low-pressure regulator type, fitted with an external round gauge scaled in MPa, and is supplied without a mounting bracket. Maximum working 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 family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options across the family include automatic or differential-pressure drains, the 40 um standard element, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Because flow is published as curves rather than a single rating, and the low-pressure type's regulation range is not in our sheet, we confirm both from the datasheet 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.

Filtering and regulating supply air to a pneumatic stamping press, where the 5 um element protects directional valves from particulate and the manual drain lets maintenance clear accumulated water at shift start.
Feeding regulated air to the cylinders on a carton-sealing conveyor, with the 3/4 in port matching the main air drop and the round MPa gauge letting operators check the setting at a glance.
Installed at a machine-level drop on a plant air ring main, combining water and particle removal with pressure regulation in one body to save panel space on the fabrication floor.
Match the size and port to the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the family, and larger sizes carry more flow. If your line is smaller, the same configuration exists in sizes 200, 300 and 400 with smaller ports. Drain choice matters: manual (this unit) needs an operator to open the drain, while automatic and differential-pressure drains discharge condensate without attention. Filter grade is 40 um standard or 5 um (code W, this unit) for finer protection. Gauge scales are MPa, psi or bar, and threads come as PT (the standard), G or NPT. This unit is the low-pressure regulator type; its exact regulation range is not published in our sheet, so we confirm it on request. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 series as curves rather than a single rated figure, so we do not quote a number. Send us your application details and we will confirm the flow from the datasheet on request before you order.
The M in the code specifies a manual drain: accumulated condensate is released by opening the drain by hand, which suits attended installations. The GFR family also offers automatic and differential-pressure drains for unattended discharge. On filtration, 40 um is the standard element, and the W code on this unit selects the finer 5 um element.
