The AirTAC GFR60025LF2WT AirTAC Filter Regulator NPT1 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60025LF2WT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single 600-size body with 1 in NPT ports. This configuration carries the W filter grade (5 um element, finer than the standard 40 um), a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises, and the low-pressure (L) regulator type for circuits set well below standard line pressures. A square pressure gauge with psi scale is fitted as standard, and the 600-size bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with 40 um or 5 um filtration, differential-pressure, automatic or manual drains, standard or low-pressure regulation, and embedded square or optional external round gauges in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

On a carton-sealing or case-erector line running actuators at low set pressures, this unit filters the shop air to 5 um and holds the regulated supply steady, with the differential-pressure drain keeping condensate out of the valves downstream.
A machining cell with air-operated clamps that must not see full line pressure uses the low-pressure regulator type to set a gentle working pressure, while the 5 um element protects the clamp cylinders and control valves from water and fine dirt.
Mounted at the inlet of a machine's pneumatic manifold, the combined filter-regulator body conditions the 1 in main feed in one mounting, the square psi gauge giving the operator a direct reading of the set pressure at the panel.
Start with the port step: the 600 size with 1 in NPT ports is the largest frame in the GFR range, chosen when the air demand at the point of use calls for the biggest port and flow capacity in the family. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. This unit is already specified with the 5 um (W) element, the differential-pressure drain, the low-pressure regulator type and a square psi gauge; if you need the standard 40 um grade, an automatic or manual drain, a different gauge scale (MPa or bar), G or PT threads instead of NPT, or standard regulation, those are the codes to compare. A mounting bracket is included.
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 figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow and sizing from the datasheet on request.
The L in the code marks the low-pressure regulator type, intended for circuits set below standard line pressures; the exact adjustment range for this type is not published, so we confirm it on request. F2 specifies the embedded square gauge with a psi scale, and MPa or bar scales are available on other codes.
