The AirTAC GFR600C25MLJNT AirTAC Filter Regulator NPT 1 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 GFR600C25MLJNT is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port for high-flow main air lines, with the standard 40 um filter element, a manual drain on the bowl, and the low-pressure regulator type for applications that hold a reduced downstream setting. No gauge is fitted and no mounting bracket is included, so add a separate gauge if a local pressure readout is needed. The aluminium alloy bowl suits the largest frame in the range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual or differential-pressure drains, a 5 um element (code W), gauge choices and scale, G or NPT thread variants, and bracket or no-bracket mounting. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding a spray-booth drop from a 1 in main: the 40 um element strips water and pipe scale before the regulator holds a reduced, stable supply to the spray equipment, and the manual drain is bled at shift checks.
Supplying taping and case-erector cylinders on a packaging conveyor: the unit filters the shop air and regulates it down to the low pressure the actuators need, with the 1 in NPT port matching the line feeding the cell.
Providing filtered, regulated air to quarter-turn pneumatic actuators on a treatment-plant skid: the low-pressure regulator type suits modest set points, and the manual drain lets maintenance purge accumulated condensate during rounds.
Start with the port step: this unit is the size 600 frame with a 1 in NPT thread, the largest combination in the GFR range, so match it to your main-line connection and expected air demand. Choose the drain to suit attendance: this unit has a manual drain, which needs periodic bleeding but tolerates low inlet pressure; automatic and differential-pressure drains are available on other codes. The fitted element is the standard 40 um grade; specify code W for 5 um where finer particulate removal matters. This code carries no gauge and no bracket, and the regulator is the low-pressure type, whose exact adjustment range is not published - confirm it with us. PT is the standard thread; G and NPT are order options, and this code is the NPT variant.
Because flow is published as curves and not as a single rated number, we cannot quote a rated flow for this unit. Send us your line size, duty and set pressure 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. 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 rated flow, Cv or SCFM number. Tell us your line size, duty cycle and set pressure and we will confirm the sizing against the datasheet on request before you order.
The MLJNT code specifies a manual drain, which you bleed periodically and which tolerates lower inlet pressure than the other options. If the installation is unattended or condensate loads are heavy, ask us for the equivalent GFR600 code with an automatic or differential-pressure drain; the filter grade, port and thread can stay the same.
