The AirTAC GFR600C25LJC1TK 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 GFR600C25LJC1TK is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 1 in NPT port for high-flow main lines, with the standard 40 um filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the bowl is high enough - no daily manual draining on lightly loaded drops. The regulator is the low-pressure (L) type, and this unit carries the external round pressure gauge scaled in MPa plus a reverse/check valve (K) that holds downstream pressure if the upstream supply is lost. 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 up to 1 in, in PT (standard), G and NPT threads, with manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, gauge choices and scale options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 on a 1 in compressed-air distribution header in a factory, it filters line-scale and condensate from the main supply and holds a steady low regulated pressure for the whole drop.
Feeding the air drops of a CNC machining cell, it cleans the incoming plant air to 40 um and regulates the supply pressure that actuates tool changers, clamps and air-powered fixtures.
Installed at the inlet of a packaging or conveyor line, it strips water and particulate before the air reaches cylinders and actuators, with the reverse/check valve holding the circuit if upstream supply dips.
Size and port are the first decision: the 600 frame with its 1 in NPT connection suits main air headers and high-consumption drops, while smaller GFR sizes cover lighter lines - match the size step to the flow your line actually needs. Drain type comes next: differential-pressure (this unit) suits steady, well-loaded drops; automatic (A) drains unconditionally; manual (M) puts draining in the operator's hands. The standard 40 um element is right for general plant air; specify the W code for 5 um where downstream equipment needs finer protection. This code is the low-pressure (L) regulator type, so confirm its adjustment window against your setpoint before ordering. Gauge, thread (PT standard, G or NPT to order) and bracket options can all be chosen per code. Because flow is published as curves rather than a single rated figure, 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 rather than a single rated figure, so we do not quote one number here. Tell us your line pressure, setpoint and expected air consumption, and we will confirm the flow curve and sizing from the datasheet on request before you order.
The L code makes this a low-pressure regulator type rather than the standard version; the exact adjustment range for this type is not published in the material we hold, so confirm your setpoint with us and we will verify it against the datasheet. The C1 code means the external round gauge, scaled in MPa, is fitted; the embedded square gauge is the standard fitting and MPa, psi and bar scales are available to order.
