The AirTAC GFR600-25 AirTAC Filter Regulator PT 1 in, Manual Drain 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 PT1" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25 is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit carries a PT 1 in port, the largest port step in the G-series range, so it sits on main supply lines rather than at a single drop. The M in the code gives it a manual drain, so collected condensate is released by opening the drain fitting during checks rather than automatically. Filtration is the standard 40 um element, and the F2 in the code fits the embedded square gauge scaled in psi so the set pressure is visible at the unit. The K code adds a reverse (check) valve, and J means the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR600 series, the top size of a range that steps from 200 through 600 with port options from 1/8 in to 1 in and PT, G or NPT threads to order. The aluminium alloy bowl on this size is suited to the larger unit, with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your line 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 0.05 - 0.9 MPa (7 - 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 on the 1 in main line feeding a production floor, it cleans water and scale out of the header air and holds a steady regulated pressure for every branch downstream, with the psi gauge readable from the wall.
Feeding the air supply to a CNC machining cell, it filters particulate from the mill's pneumatic clamping and tool-change circuits and keeps their operating pressure constant through the shift.
Mounted ahead of the cylinder bank on a packaging conveyor line, it supplies filtered air to the diverters and pushers and regulates the pressure so cylinder stroke timing stays repeatable.
Choose the 600 size with its PT 1 in port when the supply line itself is the constraint: the larger the port step, the more air the body can pass before pressure drop becomes the limiting factor. On this unit the drain is manual, which suits installations that are inspected on a schedule; if nobody walks the line, an automatic drain (code A) or the default differential-pressure drain removes the dependence on operator checks. The 40 um grade is the standard element for general plant air; the 5 um option (code W) is there when downstream equipment needs finer protection. The square gauge here reads in psi, and MPa or bar scales are available instead if your team works in those units. Thread is PT as standard, with G (BSPP) and NPT as order options, and this configuration ships without a bracket. Because AirTAC publishes flow only as curves and not as a single rated number, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The M in the code gives a manual drain: condensate collected in the aluminium bowl is released when an operator opens the drain during scheduled checks. It suits lines that are inspected regularly; if the unit runs unattended, ask about the automatic (A) or differential-pressure drain versions instead.
