The AirTAC GFR600C25MJC3TK 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body. This GFR600C25MJC3TK is the 600 size with 1 in NPT ports, a manual drain on the bowl, a 40 um filter element, a round pressure gauge reading in bar, and a built-in reverse (check) valve. The 600 size bowl is aluminium alloy, and no mounting bracket is fitted on this code. Regulation range on this manual-drain version is 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working 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 ports from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

At a press cell, the 40 um element strips water and pipe scale from the main line while the regulator holds a set pressure for the tooling, and the check valve isolates the circuit when the upstream supply is removed.
Feeding cylinders and diverters on a packaging conveyor, where stable regulated pressure keeps stroke timing consistent and the manual drain lets maintenance clear accumulated condensate at shift start.
A regulated outlet at a truck or bus maintenance bay for impact wrenches and inflation tasks: the 1 in NPT inlet suits a high-capacity shop main, and the bar-scale gauge gives technicians a direct reading at the bench.
The real, decodable choices on this family are: size and port (200/300/400/600, stepping up in port and flow capacity - match the step to your line's demand); drain type (this code is manual, while automatic and differential-pressure drains are on other codes); filter grade (40 um standard, 5 um with code W); gauge style and scale (embedded square gauge standard, external round gauge optional, MPa/psi/bar); thread (PT is the standard, G and NPT are order options); and bracket (J codes ship without one). This unit is the 600 size with 1 in NPT ports, manual drain, 40 um element, round bar gauge and a check valve.
Flow for the GFR600 series 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 the GFR600 series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the flow your application needs, and we will confirm the figures against the datasheet curves before you order.
The M in the code sets a manual drain: condensate collects in the aluminium bowl and is released by hand. Automatic (A) and differential-pressure (blank) drains are available on other GFR600 codes, as is the 5 um (W) filter element.
