The AirTAC GFR600C25AC3T 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 GFR600C25AC3T is an AirTAC GFR600 filter regulator: a single body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This unit is built for 1 in NPT ports and uses the standard regulator type with an adjustment range of 0.15-0.9 MPa (20-130 psi), backed by a 40 um filter element. An automatic drain expels collected condensate without manual attention, and the fitted round gauge reads in bar. The bowl on the 600 size is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and a mounting bracket is included.
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, plus choices of drain type, 5 um filtration (code W), gauge style and scale, G/NPT thread options and bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Clean, regulated air supplied to impact wrenches, nut runners and pneumatic clamps at assembly stations, with the automatic drain keeping condensate out of the tool circuit on high-humidity plant air.
Conditioned air for carton-sealing and palletising cylinders on a packaging conveyor, where the 1 in NPT port feeds a main branch and the regulator holds a stable setpoint for consistent stroke behaviour.
Filtered, pressure-controlled supply to pneumatic actuated ball and butterfly valves in a process plant, with the bar-scale gauge giving operators a local reading at the panel.
The real choices in this family: step size (200/300/400/600) and port (1/8 in to 1 in) against the flow your line needs; drain type - differential-pressure (default), automatic (this unit) or manual, which also sets the regulation range (0.15-0.9 MPa with automatic or differential-pressure drain, 0.05-0.9 MPa with manual drain); filter grade 40 um standard or 5 um with code W; gauge style and scale (MPa, psi or bar); thread, where PT is the standard and G and NPT are order options; and bracket or no-bracket variants. Flow for this family is published as curves, not a single rating, so 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. 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 family as curves, not as a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the datasheet on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate without anyone opening the bowl. The alternatives in this family are the default differential-pressure drain and a manual drain (code M). Note the drain type also sets the regulation range: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with manual drain.
