The AirTAC GFR600C25MJF3TK AirTAC Filter Regulator NPT1 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 GFR600C25MJF3TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This configuration is threaded NPT1 (1 in), uses the standard 40 um filter element, and has a manual drain on the bowl, so an operator opens the drain valve to expel collected condensate. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the maximum working (inlet) pressure is 1.0 MPa (145 psi). An embedded square gauge with a bar scale is fitted, a reverse/check valve (code K) is fitted, and no mounting bracket is included. At size 600 the bowl is aluminium alloy. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, an optional 5 um element (code W), gauge scales in MPa, psi or bar, PT, G or NPT threads, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to 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.

Feeding filtered, regulated air to pneumatic clamps, tool-changers and chuck actuators on a machine-shop drop, with the 1 in NPT port taking a main-header feed and the manual drain bled at shift checks.
Supplying steady regulated pressure to the air cylinders that divert, stop and index bottles along a filling-hall conveyor, where the 40 um element keeps rust and pipe scale out of the valve seats.
Conditioning house compressed air before it reaches analyzers and pneumatic sample-handling gear in a process lab, holding a fixed setpoint read on the bar-scale gauge and venting condensate manually at service intervals.
Size and port are the first decision: the 600 size with its 1 in NPT port suits the largest flows in the GFR range, while smaller sizes (200/300/400 with 1/8 to 3/4 in ports) cover lighter duties - match the step to the flow your line needs. Drain type is a real choice: this unit has a manual drain, which suits attended installations where an operator can bleed condensate regularly; automatic or differential-pressure drains suit unattended or hard-to-reach positions. The 40 um element is the standard grade; specify the W option for 5 um where finer filtration is wanted. The fitted square gauge reads in bar; MPa and psi scales are alternatives, and an external round gauge is optional. PT is the standard thread, with G and NPT as order options (this unit is NPT). A bracket is optional - this configuration ships without one.
One honest note before ordering: AirTAC publishes flow as curves, not a single rated number, so we cannot quote a rated flow figure here. Send us your application details and we will confirm the datasheet and sizing against your required flow 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 GFR600 series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet and check the sizing against your required flow on request.
The M in the code specifies a manual drain: an operator opens the drain valve to expel condensate collected in the bowl, which suits attended installations. If the unit will sit in an unattended or hard-to-reach position, the same GFR600 size is available with an automatic (A) or differential-pressure (blank) drain - ask us to quote that variant.
