The AirTAC GFR600C25C3WTK AirTAC Filter Regulator NPT1 (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 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 GFR600C25C3WTK is a size-600 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration carries a 1 in NPT port, a fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, a round pressure gauge reading in bar, and a built-in reverse/check valve that holds the downstream setting if the supply is interrupted. The standard regulator covers 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the aluminium alloy bowl is rated -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GFR line runs from size 200 through 600 with port sizes from 1/8 in to 1 in, and each size can be ordered with manual or automatic drain, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, a low-pressure regulator, and G, NPT or PT threads. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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.

Mounted at the drop from a bottling plant's main air header, the unit strips water and fine particles from the supply and holds a steady regulated pressure to the line's pneumatic actuators, with the check valve keeping the setting through compressor unload events.
CNC plasma cutting needs clean, dry, pressure-stable air at the torch. A 1 in filter regulator placed ahead of the machine's air inlet removes moisture and fine contaminant and sets the working pressure the cutting controls expect.
Sorting and diverter cylinders along a packaging conveyor need consistent pressure to switch reliably. This filter regulator cleans the supply, regulates it to the circuit's set point, and its differential drain keeps condensate off the valves without daily attention.
Size 600 with a 1 in port is the top of the GFR range, chosen when the air demand at the machine or header is at the high end; step down to 300 or 400 if your consumption is modest, since an oversized unit costs more without improving regulation. The 5 um element in this unit suits downstream equipment sensitive to fine particulate; the standard grade is 40 um if coarser protection is enough. The differential-pressure drain needs no operator attention, but if your compressor cycles heavily or the line runs at low, steady load, a manual (code M) or fully automatic (code A) drain may suit better. The fitted round gauge reads in bar; square gauges and MPa or psi scales are order options, as are G (BSPP) and PT threads instead of NPT. A reverse/check valve (K) is already fitted here, and the bracket is included. Flow for this series is published as curves, not a single rating, so send us your flow and pressure requirements 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 does not publish a single rated flow figure for the G series; flow is given as performance curves across pressure settings. We will confirm the datasheet curve figures for your operating pressure and required flow on request, so you can size the unit against your actual air consumption before ordering.
The differential-pressure drain (the default, no code letter) opens to expel collected condensate when the filter element loads up and the pressure drop across it rises, so it needs no operator input. If your duty suits scheduled draining or continuous condensate removal, the same unit can be ordered with a manual drain (code M) or an automatic drain (code A) instead.
