The AirTAC GFR600C25LJF2WTK AirTAC Filter Regulator NPT1 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 GFR600C25LJF2WTK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with a 1 in NPT port for high-flow main-line air. This configuration is the low-pressure type, fitted with the fine 5 um filter element (code W), a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge reading in psi, and a reverse/check valve that holds downstream pressure when the upstream supply is lost. The aluminium alloy bowl is standard at size 600, and no mounting bracket is included with this code.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The low-pressure regulator range for this type is not published as a single figure, and flow is published as curves rather than a rated number - ask us and we will confirm both from the datasheet 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.

On a spray booth or finishing line running at reduced line pressure, this low-pressure filter regulator dries and filters the air to 5 um and lets the operator set and hold the atomizing pressure at the gun manifold, with the psi gauge giving a direct reading at the panel.
Air-jet weaving machines take large volumes of air at modest pressure from a 1 in main. This unit filters water and particles out of that main and regulates it down to the loom's working pressure, while the check valve keeps the machine from losing its setting if the supply dips.
On a bottling or packaging hall where a 1 in header feeds grippers, pushers and clamp cylinders, this filter regulator cleans the plant air, holds a stable low working pressure across the header, and its differential-pressure drain carries off condensate without a manual blow-down routine.
Size 600 with a 1 in NPT port is the largest step in the GFR range, so start there when the line serves several large consumers and work down to 400/300/200 if the flow demand is smaller. The 5 um element (W) suits downstream equipment that needs finer particle removal than the 40 um standard; keep the standard grade where coarse protection is enough, as it holds dirt longer between services. Drain choice matters: this unit uses the differential-pressure drain, while automatic (A) and manual (M) versions exist in the family. The square gauge here reads psi; MPa and bar scales and an external round gauge are the other gauge options. Thread is NPT on this code, with PT (standard) and G available to order; brackets are optional (J means none fitted).
Because this is the low-pressure type, its regulation range differs from the standard GFR and is not published as a single figure - and flow is published as curves, not one rated number. Send us your line pressure and air demand and we will confirm the sizing 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 GFR series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your line pressure and the air demand of the equipment on the 1 in line, and we will confirm the flow from the datasheet and check the sizing for you before you order.
The L code means the regulator section is the low-pressure version rather than the standard type, so it is intended for lines where the working pressure is set below the standard range. Its exact regulation range is not published as a single figure - send us your target working pressure and we will confirm from the datasheet that this unit covers it.
