The AirTAC GFR600C20MLJF1T 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 AirTAC GFR600C20MLJF1T is a filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body. This configuration carries a 3/4 in NPT port, a manual drain bowl in aluminium alloy, the standard 40 um filter element, and the low-pressure regulator type, so it suits lines that run below ordinary working pressures. An embedded square gauge scaled in MPa is fitted for direct downstream pressure reading, and no mounting bracket or reverse/check valve is included in this code.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port options from 1/8 in to 1 in, and choices of drain type, 40 um or 5 um filtration, gauge scale, thread form and bracket. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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.

Feeding a light-duty assembly press that clamps or staking-forms parts at reduced air pressure, with the 40 um element keeping scale and pipe debris out of the regulator and valve seat.
Conditioning supply air on a laboratory or QC test bench where fixtures run at deliberately low pressures and the operator reads setpoint directly off the fitted MPa gauge.
Supplying filtered, regulated air to conveyor-mounted sorting and packaging actuators on a 3/4 in main, with the manual drain emptied during scheduled line cleaning.
Start with the port step: this unit is 600 size with a 3/4 in NPT port, the largest in the GFR range, chosen when the line's required flow points to the top of the family; smaller 200/300/400 sizes cover 1/8 in to 1/2 in. Drain type is a real choice: this code has a manual drain, which you empty by hand, while automatic and differential-pressure drains are available on other codes if you cannot visit the unit regularly. The filter element here is the standard 40 um grade; specify W for the 5 um fine grade if downstream equipment needs cleaner air. The fitted square gauge reads in MPa, and psi or bar scales are orderable. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an option. No bracket is fitted in this code, but bracketed versions exist.
One honest note before you order: AirTAC publishes flow for this family as curves, not a single rated figure, and the regulation range of the low-pressure type is not stated as a single number either. Send us your line pressure and flow requirement and we will confirm sizing against the datasheet before you commit.
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 rather than a single rated number, so we do not quote a figure here. Tell us your line pressure and the flow your equipment needs, and we will confirm the correct sizing against the datasheet on request.
The M in the code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by hand, which suits lines visited during regular maintenance. If you cannot drain by hand, GFR codes with automatic or differential-pressure drains are available - just ask and we will decode the right variant for you.
