The AirTAC GFR600C25LC2G AirTAC Filter Regulator G1 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 GFR600C25LC2G is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a G1 (1 in) G-thread port, the standard 40 um filter element, and a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. It is the low-pressure regulator type, fitted with an external round gauge scaled in psi, and includes a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drains, a 40 um standard or 5 um (code W) element, and square or round gauges in MPa, psi or bar scales. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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.

On a CNC fixture line that clamps workpieces with air cylinders running at reduced pressure, this unit filters the plant air supply and holds a gentle, stable regulated pressure so delicate parts are held without crushing.
On the 1 in main air drop feeding a packaging machine's valve manifold, the 40 um element strips water and pipe scale before the valves, while the low-pressure regulator keeps actuator pressures where the machine was set up to run.
On process lines where quarter-turn valve and damper actuators are sized for a specific operating pressure, this unit cleans the supply air and lets maintenance set the actuator pressure from the round psi gauge at the unit.
Start with the port step: this unit is the size-600 frame with a G1 (1 in) G-thread port, the largest in the GFR range - match it to your line size and expected air demand, and step down to 200/300/400 with 1/8 to 3/4 in ports where flow is smaller. The 40 um element is the standard grade for general plant air; if you need finer filtration, the W-coded 5 um element is the alternative. Drain choice matters: this unit uses the differential-pressure drain (no operator action), while automatic (A) and manual (M) drains are the other catalogue options. The round psi gauge here is one of the scale options (MPa, psi, bar) alongside the embedded square gauge. Thread is G (BSPP) on this code; PT is the standard and NPT is also an order option. A mounting bracket is included.
One honest routing note: because this is the low-pressure regulator type, its set-point range differs from the standard type and AirTAC publishes flow only as curves, not a single rating - ask us to confirm the regulation range and 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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line size and air demand and we will confirm the flow curve and sizing from the datasheet on request before you order.
The C2 in the code means an external round gauge scaled in psi is fitted (the embedded square gauge in MPa, psi or bar scales is the other option). The L in the code marks the low-pressure regulator type, whose set-point range differs from the standard type - we confirm the exact range from the datasheet on request.
