The AirTAC GFR600C25AJC1WTK 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 AirTAC GFR600C25AJC1WTK 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 built around a 1 in NPT port for high-flow main lines, a fine 5 um filter element (code W) for cleaner air than the standard 40 um grade, an automatic drain that expels collected condensate without operator attention, and a reverse/check valve that helps hold the downstream setting if upstream supply is interrupted. The fitted round MPa gauge gives a clear external pressure readout, and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing). At size 600 the metal bowl is aluminium alloy, and this unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options for drain type, filter grade, gauge style and scale, thread form (PT standard, with G and NPT as catalogue options) and bracket. Flow is published by AirTAC as curves rather than a single rated figure, so we 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.

Drops feeding a whole production bay from a 1 in compressed-air header get one unit that both cleans the air and holds a stable header pressure for every machine downstream.
The 5 um element and steady regulated pressure protect spindle-air seals, tool-changer cylinders and pneumatic clamps on a machining centre from water carry-over and pressure swings.
Unattended high-flow lines running cylinders, vacuum generators and air-driven case sealers benefit from the automatic drain and check valve, which keep conditioning maintenance-free and the setting held.
Size 600 with a 1 in port sits at the top of the GFR range, so step up to this configuration when your line flow demands the largest port in the family; smaller sizes 200/300/400 cover lighter duties. The 5 um element (W code) suits air tools, instrumentation and valves that need finer filtration than the standard 40 um grade. The automatic drain (A code) is the low-maintenance choice where the unit is hard to reach or the line runs unattended; manual and differential-pressure drains remain available in the family. The round MPa gauge is fitted here; square embedded gauges and psi or bar scales can be specified instead. NPT thread is ordered as this code's option - PT is the catalogue standard and G (BSPP) is also available. A bracket can be added if you need panel or wall fixing, since this code omits it.
Because AirTAC publishes flow as curves rather than a single rated number, 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 GFR series as curves, not as a single rated figure, so we do not quote a flow number. Tell us your line pressure and air demand and we will confirm the correct sizing from the datasheet on request.
The A code in the model specifies an automatic drain, which discharges collected condensate from the aluminium alloy bowl on its own instead of waiting for manual bleeding. The K code adds a reverse/check valve, which helps hold the downstream pressure setting if the upstream supply is lost.
