The AirTAC AirTAC GFR600C20MJF2G Filter Regulator G3/4 (3/4 in) 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 GFR600C20MJF2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G3/4 (3/4 in) G-thread port, a 40 um standard filtration element, a manual drain on the bowl, and a fitted embedded square gauge scaled in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Because this is the 600 size, the bowl is aluminium alloy, and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, manual or automatic or differential-pressure drains, a 5 um (code W) element in place of the 40 um standard, gauge scale choices, and optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Placed ahead of a CNC machine tool's pneumatic valve stack and clamping circuits, this unit removes water and pipe scale from the shop air and holds a steady regulated pressure so clamps and tool-changers act consistently.
On a carton-forming or case-packing conveyor line, the unit filters condensate and dirt out of the header air and regulates the pressure feeding the pick-and-place and sealing cylinders, protecting seals from overpressure and moisture.
Mounted at the air drop feeding a spray booth's gun manifold, the unit strips water and particulates from the compressed air and lets the operator set and hold the regulated pressure the spray job calls for.
Size and port are the first choice: 600 is the largest GFR frame, and this unit steps up to a G3/4 (3/4 in) G-thread connection, so match it to the line size and required flow - we can confirm the flow curve against your demand before you order. The 40 um element suits general plant air; specify the 5 um (W) element where finer filtration is needed. The manual drain on this unit means an operator opens the drain periodically, which suits attended installations; automatic or differential-pressure drains are available if the bowl is hard to reach. The fitted square gauge reads in psi, with MPa or bar scales and an external round gauge available as options. Thread is G here, with PT standard and NPT orderable, and note this configuration has no mounting bracket.
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 figure, so we do not quote a l/min or SCFM number. Send us your line pressure and air demand and we will confirm the flow from the datasheet curve for this exact unit before you order.
The M in the code specifies a manual drain: an operator opens the bowl drain periodically to expel collected water. If the unit will be mounted where regular access is difficult, the same GFR600 frame can be ordered with an automatic drain (code A) or a differential-pressure drain (blank), and the regulator range differs slightly by drain type - 0.05-0.9 MPa (7-130 psi) with the manual drain fitted here.
