The AirTAC GFR600C25C3TK 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 GFR600C25C3TK is an AirTAC GFR-series filter regulator: water and particulate removal plus downstream pressure regulation combined in a single body. This size 600 unit is threaded 1 in NPT, carries the standard 40 um filter element, and drains collected condensate by differential pressure. Its aluminium alloy bowl suits the larger 600-size mains, the fitted round gauge reads in bar, and a reverse/check valve plus mounting bracket are included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, optional 5 um filtration (code W), automatic or manual drains, an embedded square gauge or an external round gauge in MPa, psi or bar scales, and PT, G or NPT threads. 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.

Point-of-use conditioning on the compressed-air main feeding a bottling hall: water and pipe scale removed at 40 um and header pressure regulated before it reaches the fill, capping and labelling machines.
Supplying filtered, regulated air to the cylinder-driven stops, pushers and diverters on a carton-packaging conveyor line, with the round bar gauge giving operators a local pressure check at the drop point.
A single-body filter regulator at the inlet of a machine builder's pneumatic control panel, with the reverse/check valve holding downstream settings and the included bracket fixing the unit to the panel frame.
Size and port set the flow path: 600 is the largest G-series size, here with a 1 in NPT port, so step up or down through 200/300/400/600 to match the line. Choose the drain: differential pressure (this model, no drain fitting to operate), automatic (code A) or manual (code M) - and note the setting range differs by drain type, 0.15-0.9 MPa (20-130 psi) with this differential-pressure drain. Filter grade is 40 um standard or 5 um with code W. Gauge scale is selectable (MPa, psi or bar; this unit reads bar) and thread can be ordered as PT (standard), G or NPT. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and required flow and we will confirm the correct size from the datasheet before you order.
This unit discharges collected condensate whenever the pressure differential across the filter element is high enough, with no drain fitting to operate. Automatic (code A) and manual (code M) drains are catalogue options, and the regulator setting range differs by drain type: 0.15-0.9 MPa (20-130 psi) with this differential-pressure drain versus 0.05-0.9 MPa (7-130 psi) with a manual drain.
