The AirTAC GFR600C25MJF1WT AirTAC Filter Regulator 1 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 AirTAC GFR series combines water-and-particulate filtration with pressure regulation in a single body, so one 600-size unit both cleans the compressed air and holds a stable downstream pressure. This configuration is built around a 1 in NPT port for high-flow supply lines, a 5 um filter element (code W) for finer protection than the 40 um standard, a manual drain you open by hand to expel collected condensate, an embedded square pressure gauge reading in MPa, and a standard regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range. The metal bowl on this 600 size is aluminium alloy, and no mounting bracket is included.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or differential-pressure drains, 40 um or 5 um filtration, different gauge scales, and G (BSPP), NPT or PT threads. Flow is published in the AirTAC catalogue 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.

Installed at the head of a paint-shop distribution line, the unit strips water and fine particulate from the compressed air feeding spray equipment and holds the header at the pressure the booth controls were set up for, with the manual drain emptied during shift checks.
Mounted on the supply drop to a filling and capping conveyor, the unit cleans the air reaching cylinders and grippers and regulates it to the setting the machine builder specified, protecting valves from water carryover on a 1 in main.
Fitted ahead of a machining centre's clamping manifold, the unit removes condensate and 5 um particles before the air reaches the clamping valves and holds a steady regulated pressure so fixture clamping behaves consistently across the shift.
Start with the port step: this unit is the 600 size with a 1 in NPT port, the largest in the G-series range, so match it to the supply line and the air demand of the equipment downstream. Choose the drain to suit attendance: this unit has a manual drain that must be opened by hand, whereas automatic and differential-pressure drains are available in the same family if the installation is unattended. The 5 um element (code W) suits finer downstream needs; the 40 um standard element remains available if coarse protection is enough. The fitted square gauge reads in MPa, with psi and bar scales and an external round gauge available as options. PT is the standard thread for this series, with G (BSPP) and NPT as catalogue options to order - this unit is specified with NPT. A mounting bracket can be ordered; this configuration ships without one. 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 in the catalogue, 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 specifies a manual drain: condensate collected in the aluminium bowl is released by opening the drain by hand, so someone needs to attend the unit periodically. If the installation runs unattended, the same GFR600 family is available with an automatic or differential-pressure drain instead - note that the regulator adjustment range also differs by drain type, with the manual-drain version covering 0.05-0.9 MPa (7-130 psi).
