The AirTAC GFR600C25LJF2WT AirTAC Filter Regulator NPT1 in, 5 um 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, so one 1 in ported unit conditions the air and sets the downstream pressure at the same time. This configuration, the GFR600C25LJF2WT, is the size 600 low-pressure type with a 1 in NPT port, a 5 um filter element (code W), a differential-pressure drain on the bowl, an embedded square gauge scaled in psi, and no mounting bracket. The 600 size bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options that include manual or automatic drains, a 40 um standard element or the 5 um W grade, gauge scale in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published 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.

Feeding the valve manifold of a robotic welding cell: the 5 um element keeps spools and pilot valves clear of particulate and condensed water, while the low-pressure regulator holds a gentle, stable supply pressure to the gripper and clamp circuits.
Mounted at the drop point of a cartoning or case-packing conveyor, the 1 in port serves the line's main air drop, the differential-pressure drain keeps the aluminium bowl emptied during production, and the psi gauge lets the line technician read the setpoint at a glance.
Supplying atomizing air to an industrial paint spray booth, where the low-pressure regulator type matches the modest setpoints that coating work demands and the 5 um grade helps keep finish quality free of water and particle defects.
Start with the port step: size 600 with a 1 in port is the largest GFR frame, so match it to the pipe size and the air demand of the circuit rather than upsizing blindly. Then set the drain: differential-pressure (the default on this model) bleeds the bowl as the pressure drop across the element builds, while automatic (A) and manual (M) versions are available in the family. This unit carries the 5 um W element; the standard grade is 40 um, so choose W where downstream valves and instruments need finer protection. Because this is the L low-pressure type, confirm the adjustment range suits your setpoint before ordering - the exact range is not published on our sheet and we will confirm it on request. The embedded square gauge here reads in psi; MPa and bar scales are the alternatives. Thread is NPT on this code, with PT as the standard and G also orderable, and the J code means no bracket is fitted - order a bracketed version if you want panel or wall fixing. Finally, flow is published as curves, not a single rating, so send us your application details 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 publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a figure that could be misleading. Send us your line pressure, setpoint and expected air demand, and we will confirm the datasheet curve and sizing for this 1 in unit on request.
L marks the low-pressure type of regulator, intended for applications where the controlled pressure sits below the range of the standard version. The exact adjustment range for the low-pressure type is not published on our sheet, so please confirm it with us before ordering. Regulation applies only to the regulator side of this filter regulator - the 5 um filtration and differential-pressure drain are separate functions of the same body.
