The AirTAC GFR600C25AJNWT 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 GFR600C25AJNWT is a filter regulator: one body removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This unit sits on the size-600 frame with a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain that bleeds collected condensate without anyone opening the bowl, and an aluminum alloy bowl - the material AirTAC uses at the 600 size. No gauge is fitted and no mounting bracket is supplied.
This is a genuine AirTAC part. The GFR line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um elements, and gauge choices. Flow figures are published as curves rather than a single rating, 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.

Point-of-use conditioning on a 1 in distribution header in a plant air house: dropping header pressure to the working setpoint while knocking water and pipe scale out of the supply before it reaches the floor.
Supplying clean, regulated air to quarter-turn actuators on large process valves in a water-treatment or wastewater plant, where a stable setpoint protects positioners, solenoids and actuator seals.
Feeding the main air drop of a bottling or canning line, where the 5 um element helps keep actuators, grippers and spray nozzles free of water and particulate carried in from the receiver.
The real, decodable choices on this family are the size and port step, the drain type, the filter grade, the gauge and its scale, the thread and the bracket. This unit is already fixed at the top of the range: size 600 with a 1 in NPT port, a 5 um element, an automatic drain, no gauge and no bracket. The regulation range is 0.15-0.9 MPa (20-130 psi) with the automatic drain fitted, and the maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. If you would rather have a gauge, a bracket, a 40 um element or a different thread, those are order options on the same series. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing from 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 GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure, setpoint and expected air demand and we will confirm the flow from the datasheet for this exact model before you order.
This configuration is ordered without a gauge (code N); gauges and their scales are order options on the GFR series if you want one. The automatic drain bleeds condensate from the aluminum bowl by itself, so no one has to open a manual drain - useful on lines that run unattended.
