The AirTAC GFR600C25AJNT 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 GFR600C25AJNT is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your set point. This 600-size unit is built around a 1 in NPT port for high-flow supply lines, with a 40 um filter element as the standard grade, an automatic drain that ejects collected condensate without manual attention, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). No pressure gauge is fitted with this configuration and no mounting bracket is included; the 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and can be ordered with manual or differential-pressure drains, a 5 um (W) element, an embedded square or external round gauge in MPa, psi or bar scales, a reverse/check valve, a bracket, and PT or G thread as alternatives to NPT. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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 compressed-air distribution main serving a production hall, the GFR600C25AJNT filters bulk water and pipe scale from the supply and holds a steady header pressure for every downstream drop.
On a bottling or cartoning line with many cylinders and actuators fed from a large-bore trunk line, this unit cleans the air and keeps regulator pressure stable so sorting and transfer motions repeat consistently.
At a maintenance bay or assembly cell running impact wrenches and air ratchets from 3/4 to 1 in drops, the automatic drain keeps condensate out of the tools while the regulator sets a safe working pressure.
Size up a GFR by port and flow: this 600-size unit carries a 1 in NPT port, the largest step in the range (06=1/8, 08=1/4, 10=3/8, 15=1/2, 20=3/4, 25=1). Choose the drain to match maintenance practice: automatic (as here) drains itself, manual suits attended installations, and differential-pressure is the catalogue default. The 40 um element is standard; specify the W code for 5 um where finer particulate capture matters. Gauge, scale (MPa/psi/bar), reverse/check valve, bracket and thread family (PT standard, G or NPT to order) are all selectable codes. Because flow is published as curves rather than a single rating, 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 the GFR600 as curves, not as a single rated number, so we do not quote a figure here. Tell us your line size and demand and we will confirm the flow data from the datasheet for your application before you order.
The A in the code selects the automatic drain, which expels collected condensate on its own instead of waiting for a manual or differential-pressure drain cycle. The N code means no pressure gauge is fitted; a square or round gauge in MPa, psi or bar scales can be selected on other GFR600 configurations.
