The AirTAC GFR600C20MLC1T AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR600C20MLC1T is an AirTAC GFR-series filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air through a 40 um element and holds a set downstream pressure, with no lubricator in this family. This size 600 unit carries a 3/4 in NPT thread, a manual drain on the bowl, the low-pressure regulator type, and a round pressure gauge with an MPa scale. The bowl on size 600 units is aluminium alloy, a mounting bracket is included, and no reverse/check valve is fitted. Maximum working (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 family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and each size can be ordered with manual, automatic or differential-pressure drain, a 5 um (W) element instead of the standard 40 um, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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.

Feeds clean, regulated air to the cylinders and actuators on a cartoning or wrapping line, with the manual drain serviced as part of the shift checklist.
Sits upstream of a workholding or clinching press circuit, filtering water and chips from the shop air and holding the pressure the tooling was set up for.
Provides the filtration-and-regulation stage for a robot cell's valve manifold, with the round MPa gauge giving operators a direct read of set pressure.
Start with the port step: this unit is size 600 with a 3/4 in NPT thread, the largest port in the GFR range, so step down to GFR300 or GFR400 if the line is smaller. Drain choice matters in practice: the manual drain on this model needs someone to open it during service, while automatic and differential-pressure drains discharge condensate without attention - choose manual only where visits to the unit are already routine. The standard element is 40 um; order the W variant if the 5 um grade is required. Gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order) are selected at ordering, and a bracket is included with this unit. 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 the GFR series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of your equipment and we will confirm the flow and datasheet figures for this exact model on request.
The M in the code sets the manual drain: condensate collects in the bowl until someone opens the drain. If the unit is not visited regularly, the same GFR600 body can be ordered with an automatic (A) or differential-pressure (blank) drain instead - both discharge condensate without operator attention.
