The AirTAC GFR600C25MJF2G AirTAC Filter Regulator G1 with Gauge 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 GFR600C25MJF2G is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1 (1 in) G-thread port, a manual drain bowl in aluminium alloy (size 600 bowls are metal, not polycarbonate), a standard 40 um filter element, and an embedded square gauge reading in psi. The standard regulator adjusts from 0.05-0.9 MPa (7-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket and no reverse/check valve are fitted in this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with automatic, manual or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

Feeding clean, regulated air to the clamp and chuck cylinders on CNC machining fixtures, where the operator sets and reads the clamping pressure on the psi gauge and drains accumulated water by hand at shift start.
Conditioning the air supply to carton-forming and case-sealing cylinders on a packaging conveyor, filtering out water and pipe scale at a single 1 in drop and holding a stable setting for consistent seal-ram travel.
Regulating and cleaning the atomizing air feed to paint spray guns in a finishing booth, with the manual-drain metal bowl emptied during booth clean-down to keep moisture out of the finish.
Size and port are the first decision: step up through 200, 300, 400 and 600 (here 600 with a G1, 1 in port) as your air demand grows, and confirm the match against the published flow curves before ordering. Drain type is a real choice on GFR: this unit has a manual drain you operate by hand, while automatic and differential-pressure drains are available if you cannot rely on regular drain checks. Filter grade is 40 um as standard here, with the 5 um W option when finer filtration is needed. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G on this code, with PT and NPT orderable as specifications, and a mounting bracket can be added where this code omits it.
One honest note on sizing: AirTAC publishes flow for this family as curves, not a single rated number, so send us your application details and we will confirm the correct size from 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 for the GFR family as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application details and we will confirm the flow figures from the datasheet on request.
The M in the code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by operating the drain by hand, which suits installations checked on a regular schedule. If you cannot rely on manual checks, the same size 600 filter regulator can be ordered with an automatic drain or the default differential-pressure drain instead.
