The AirTAC GFR600C25LC2TK 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 GFR600C25LC2TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size-600 unit is built for a 1 in NPT port and carries the L code, marking it as the low-pressure regulator type. It filters to 40 um (the standard element), drains condensate by differential pressure, and has a metal bowl - at size 600 the bowl is aluminium alloy. A round external gauge scaled in psi is fitted, a reverse (check) valve is built in, and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT (standard), G (BSPP) or NPT thread, with differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, embedded square or optional external round gauges in MPa, psi or bar scales, and an optional reverse valve. AirTAC publishes regulator flow as curves rather than a single rated figure, and the exact regulation range of the low-pressure variant is not stated in the catalogue - ask us and we will confirm the flow and datasheet figures for this exact model against 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.

Conditioning the 1 in main air drop feeding a palletizer's cylinder bank: water and 40 um particulate removed upstream of the valves, with regulated pressure supplied to the clamp and pusher actuators and the check valve blocking backflow if the upstream supply dips.
Filtering and regulating the compressed air feeding a conveyor section's pneumatic drive cylinders and product stops, with the metal bowl collecting condensate from a humid plant main and the differential-pressure drain bleeding it off automatically in service.
Supplying filtered, reduced-pressure atomizing air to spray guns in a paint booth: the 40 um element keeps water and dirt out of the gun and finish, and the low-pressure type regulator is the catalogue variant for lines regulated below the standard type's range.
The decodable choices on this family: size and port step (200/300/400/600, 1/8 in to 1 in) should be matched to the air demand of the line - because flow is published as curves and not as a single rating, send us your demand and we will confirm sizing before you order. Drain type: differential-pressure (this model), automatic (A) or manual (M). Filter grade: 40 um standard or 5 um with code W. Gauge: an embedded square gauge is standard and an external round gauge (this model, psi scale) is optional, with MPa, psi or bar scales. Thread: PT is the standard; G (BSPP) and NPT (this model) are catalogue options to order. Regulator type: standard or low-pressure (L, this model) - for the low-pressure variant the exact range is not published, so confirm it with us. Bracket: included on this model.
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 regulator flow as performance curves, not as a single rated number, so we do not quote a figure here. Send us your line's air demand and operating pressure and we will confirm from the datasheet whether the size-600 unit at 1 in NPT is correctly sized, before you order.
The L in the code marks the low-pressure regulator type, the catalogue variant used where regulated pressure sits below the standard type's range; its exact range is not published, so we confirm it on request. The fitted round gauge is scaled in psi. An embedded square gauge is the standard fitting, and MPa or bar scales are the other catalogue options.
