The AirTAC GFR600C25MC1T 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 GFR600C25MC1T is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration is sized for a 1 in NPT port, filters to a 40 um grade, uses a manual drain, and carries an external round gauge scaled in MPa. The 600-size bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, plus a choice of drain type, 40 um or 5 um (code W) filtration, gauge style and scale, and bracket options. We confirm flow and other datasheet figures on request, since flow is published as curves rather than a single rating.

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 compressor drop feeding a CNC machining center, it strips water and swarf-laden particulate from the shop air and lets the setter dial in the supply pressure the machine's air-operated components are specified for.
Mounted ahead of the cylinder and actuator bank on a carton-sealing or palletizing conveyor, it keeps moisture and dirt out of the valve stack and gives the line technician one point to set and read the working pressure.
Fitted upstream of the pneumatic valve manifold on a bottling line, it delivers clean, regulated air to the fill and capping actuators, with the manual drain opened during scheduled changeover to empty collected condensate.
Within the GFR series the real, decodable choices are: size and port (200/300/400/600, 1/8 to 1 in) stepped against the air demand of the line; drain type - differential-pressure (default), automatic (code A) or manual (code M, as on this unit); filter grade - 40 um standard or 5 um with code W; gauge - embedded square or external round, scaled in MPa, psi or bar; thread - PT standard, with G (BSPP) or NPT ordered as options; and bracket. On this 600-size unit the bowl is aluminium alloy. 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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and the air demand of your equipment, and we will confirm the correct sizing from the datasheet on request before you order.
The M code in GFR600C25MC1T specifies a manual drain: water and particulate collect in the aluminium alloy bowl and a technician opens the drain by hand as part of routine checks. The series also offers automatic (code A) and differential-pressure (default) drains if you prefer the bowl to discharge without manual attention.
