The AirTAC GFR600C25ANWT 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 GFR600C25ANWT is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one 600-size body with a 1 in NPT port. This configuration carries the W filter element (5 um, against the 40 um standard), an automatic drain that ejects collected condensate without manual attention, and a standard regulator with an adjustment range of 0.15-0.9 MPa (20-130 psi). Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy. No gauge is fitted on this variant and no reverse/check valve is included; a mounting bracket is included.
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, and can be ordered with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge or no-gauge variants, and PT (standard), G (BSPP) or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Installed on a 1 in distribution drop off the compressor-room main, it filters water and pipe-scale from the plant air supply and holds a steady regulated pressure to an entire production hall section.
Feeding cylinders, grippers and clamping devices along a packaging conveyor, the 5 um element protects valve spools from particulate while the regulator keeps actuator speeds consistent as demand fluctuates.
Supplying the clamping and tool-change circuits of a CNC machine cell, where the automatic drain keeps condensate out of the circuit during unattended shifts and the regulator holds the clamping pressure the fixture was set up for.
Step up through the GFR sizes (200, 300, 400, 600) and their port sizes (1/8 in to 1 in) according to the air demand of the circuit - this 600-size unit with a 1 in NPT port sits at the top of the range for high-flow mains and headers. Choose the drain to suit attendance: automatic (as here) for unattended duty, manual where periodic draining is acceptable, or the differential-pressure default. Choose the 5 um W element where downstream equipment needs finer filtration than the 40 um standard. If a pressure readout is needed, gauge variants with different scales exist in the series - this code is supplied without a gauge. Thread is PT as standard with G (BSPP) and NPT as order options; this unit is the NPT variant. A bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we deliberately quote none. Send us your flow and pressure conditions and we will confirm against the datasheet that this size is right 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 GFR family as curves rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm against the datasheet whether this 600-size, 1 in NPT unit suits your application before you order.
In the code GFR600C25ANWT, the A selects the automatic drain, which ejects collected condensate by itself instead of relying on manual draining, and the N position means no gauge is fitted. If you need a local pressure readout, gauge variants of the GFR600 with different scales are available in the series - just ask and we will identify the right code.
