The AirTAC GFR600C25C2TK 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 GFR600C25C2TK is a size-600 filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the element rises, and a metal bowl (size 600 bowls are aluminium alloy). The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) setting range, a round external gauge reading in psi is fitted, and a reverse/check valve holds the downstream setting if upstream supply is interrupted. A mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G (BSPP) or NPT threads to order. Drain types (differential-pressure, automatic or manual), a 5 um element (code W), gauge scale and low-pressure variants are available across the range. Flow is published as curves rather than a single rating, 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 at the take-off from a factory compressed-air ring main, it filters bulk water and pipe scale from the 1 in supply line and holds a steady header pressure for the whole work area.
Feeding the valve stack on a carton-forming and conveyor section, it delivers cleaned air at a fixed setting so cylinders and grippers repeat the same stroke behaviour shift after shift.
Supplying test benches and impact tools in a heavy-vehicle service bay, it removes moisture from the shop supply and lets the technician set and read a stable test pressure on the psi gauge.
Start with the port: this unit is the 1 in NPT version of the size-600 body, the largest step in the GFR range, so match it to your main line size and let the published flow curves - not a single rated figure - decide if a smaller size would do. The 40 um element suits general plant air; specify the W option if you need 5 um. The differential-pressure drain on this model needs no timer or operator attention, but if your line sees low and intermittent flow, an automatic or manual drain variant may suit better. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread and G (BSPP) or NPT are order options - this unit is specified with NPT. A bracket is included; a reverse/check valve (K) is fitted. Before ordering, send us your flow and pressure requirements and we will confirm sizing against the datasheet curves.
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, not as a single rated number, so we do not quote a figure here. Tell us your working pressure, setting pressure and expected air demand, and we will confirm the flow from the datasheet curve for this 1 in NPT size-600 unit before you order.
This model's differential-pressure drain opens to discharge collected condensate automatically when the pressure drop across the 40 um element rises as the bowl fills - no operator action or timer is needed. If your air demand is very low or intermittent, the automatic (code A) or manual (code M) drain variants are the catalogue alternatives; ask us which suits your duty cycle.
