The AirTAC GFR60025JC3T AirTAC Filter Regulator NPT 1 in 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 PT1" 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one 1 in NPT connection handles both jobs on a compressed-air line. This configuration, the GFR60025JC3T, is the size-600 unit with a 1 in NPT port, standard 40 um filtration, a differential-pressure drain that bleeds condensate as flow passes through, a fitted round pressure gauge reading in bar, and no mounting bracket. The aluminium-alloy bowl suits this large frame, and the standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) at up to 1.0 MPa (145 psi) inlet, with an operating temperature of -5 to 70 C (non-freezing).
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, optional 5 um filtration (code W), automatic or manual drain variants, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT thread options, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet 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.

Installed at the plant-air drop feeding a bottling hall, it filters bulk water and pipe scale out of the compressed air and holds a steady regulated pressure for the filler's pneumatic actuators.
Mounted at the head of a palletizing conveyor's air drop, it cleans the supply and sets a fixed working pressure so stoppers, pushers and transfer cylinders stroke consistently through the shift.
Placed upstream of a big directional-valve manifold on a press or material-handling line, it removes condensate and particles that would score spools and keeps supply pressure within the valve's rated band.
Start with the port and size step: the 600 frame with a 1 in NPT connection is the largest GFR option, chosen when the line's required flow sits above what a 3/4 in or smaller unit can pass - match the curve to your demand rather than guessing. Choose the drain next: this unit's differential-pressure drain is the fit-and-forget default; pick automatic (code A) for unattended condensate removal or manual (code M) where you want controlled draining. The 40 um grade here is the standard element; specify 5 um (code W) only if downstream equipment needs finer filtration. The fitted round gauge reads in bar (scale 3); square or MPa/psi scales are alternatives. Thread is NPT here, while PT is the catalogue standard and G (BSPP) is also orderable. This code carries no bracket (J), so plan your own mounting.
One honest note on sizing: AirTAC publishes flow for this series as curves, not a single rated figure, so send us your application's flow and pressure requirements and we will confirm the correct size 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 GFR600 series as performance curves rather than a single rated number, so there is no one l/min or SCFM figure we can quote. Tell us your line pressure and required flow and we will confirm from the datasheet curves whether this 1 in NPT unit is correctly sized for your application.
The differential-pressure drain (the default, no letter in the code) uses the pressure drop across the filter element to bleed off collected condensate, with no operator intervention. If your compressor cycles or the unit sits in an unreachable spot, the automatic drain (code A) is the better choice; use manual (code M) only where someone can drain the bowl on a schedule.
