The AirTAC GFR600C25ALC2GK AirTAC Filter Regulator G1 (1 in) 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 GFR600C25ALC2GK is a GFR-series filter regulator: one body removes water and particulate from compressed air and holds downstream pressure at a set point. This size-600 unit has a G1 (1 in) port, an automatic drain that ejects collected condensate without manual attention, a 40 um filter element, and the low-pressure regulator type. A round gauge scaled in psi is fitted, a reverse/check valve is built in, a mounting bracket is included, and the aluminium alloy bowl suits this larger frame. Max inlet pressure is 1.0 MPa (145 psi) and the operating 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 ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), a 5 um optional element (code W), gauge styles and scales, PT/G/NPT thread options and bracket choices. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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.

Point-of-use preparation on 1 in distribution drops that feed impact wrenches, nutrunners and clamping fixtures along a body-shop line.
Filtering and regulating the shop-air feed into a machining cell so spindle enclosures, pallet clamps and blow-off nozzles see clean, settled air.
Conditioning the air that drives stopper cylinders, diverters and gating on a high-throughput packaging and palletising conveyor system.
The real choices in this family are the size and port step against the flow your line needs, the drain type (differential-pressure as standard, automatic or manual), the filter element (40 um standard, 5 um with code W), the gauge style and scale (embedded square as standard, external round, scaled in MPa, psi or bar), the thread (PT standard; G and NPT as order options) and the bracket. This configuration already fixes those at G1, automatic drain, 40 um, round psi gauge, G thread, low-pressure regulator type and reverse/check valve fitted. Because flow is published only as curves, not a single rated number, ask us to confirm sizing against your application before ordering.
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 a number here. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request.
A sets an automatic drain, which ejects condensate from the aluminium alloy bowl without manual intervention. L sets the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so we confirm it on request. C2 adds a round gauge scaled in psi, G is the G (BSPP) thread on the G1 (1 in) port, and K means a reverse/check valve is fitted.
