The AirTAC GFR600C25AJC1WT 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 GFR600C25AJC1WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 5 um filter element (the tighter of the two published grades), an automatic drain that discharges collected condensate without manual attention, a round pressure gauge scaled in MPa, and no mounting bracket. The large 1 in NPT port suits high-flow main lines. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range for this automatic-drain version is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge and scale options, PT (standard), 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 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.

Drops feeding a whole packaging hall need water and particulate stripped out and a steady regulated pressure. A 1 in filter regulator sits on the main line, the automatic drain keeps condensate off the floor, and the 5 um element protects every downstream valve and cylinder.
Pneumatic conveyor diverters and gate actuators on a bottling line run best on clean, regulated air. This unit filters the supply to 5 um, holds the line pressure set on the MPa gauge, and its automatic drain handles the condensate load from a humid compressor room.
Positioners and pilot valves on a process skid need fine filtration and stable pressure. Feeding the manifold through this filter regulator removes 5 um particles and moisture, and the round gauge lets technicians verify setpoint during calibration rounds.
Size and port are the first decision: step up through 200/300/400/600 as required flow and line size grow, and match the port to your piping - here that is the largest step, 1 in NPT. Drain type matters in service: automatic drain (this unit) empties the bowl on its own, manual drain relies on an operator, and the differential-pressure default drains on a pressure drop. Filter grade is a real choice: 40 um is the standard element and 5 um (code W, fitted here) protects finer downstream equipment. Gauge options are the embedded square gauge or the external round gauge fitted here, with MPa, psi or bar scales; thread is PT as standard with G and NPT as orderable options, and a bracket is optional. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 the GFR600 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and required flow and we will confirm the datasheet curve and correct sizing for your application on request.
This unit carries drain code A, the automatic drain, which discharges collected condensate from the aluminium alloy bowl without an operator. It suits unattended or high-humidity installations; manual and differential-pressure drain versions are available in the same series if you prefer a different arrangement.
