The AirTAC GFR600C25MLC2TK AirTAC Filter Regulator NPT1 Low-Pressure 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 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a 1 in NPT port, manual drain, standard 40 um filter element, low-pressure regulator type, a round gauge with psi scale, a reverse/check valve, and the included mounting bracket. The size 600 bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -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 to 1 in, and options including automatic or manual drains, a 5 um (W) filter element, square or round gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of the PT standard. Rated flow is published only as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Feeding grip and pusher cylinders on a beverage bottling line, where filtered, low-pressure-regulated air keeps bottle handling steady and repeatable at the filler and capper stations.
Supplying workholding clamps on a CNC machining cell; the 40 um element protects clamp valves from water and condensate while the regulator sets the clamp circuit pressure.
Running diverter and stopper gates on a packaging conveyor, with the reverse/check valve holding downstream pressure if supply dips and the manual drain cleared at shift checks.
Size 600 with a 1 in NPT port is the largest step in the GFR range; choose it when your line's flow demand sits above what smaller ports serve - we can check the published flow curves against your consumption before you order. The manual drain means an operator opens the bowl drain periodically, which suits attended installations; automatic and differential-pressure drains are available on other codes. The 40 um element is the standard grade (5 um is the W option), the round gauge here reads in psi (MPa and bar scales exist), and the low-pressure regulator type is intended where regulated settings sit below the standard range - its exact range is not published, so confirm it with us. NPT is an order option; PT is the catalogue standard, and G (BSPP) is also available. 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. Send us your line's air consumption and working pressure and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: an operator opens the bowl drain at intervals instead of relying on an automatic or differential-pressure drain. The L selects the low-pressure regulator type, intended for regulated settings below the standard range; its exact range is not published, so confirm it with us before ordering.
