The AirTAC GC600C25ALF2GK AirTAC F.R.L. Combination G1 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600C25ALF2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared set. This configuration is the size 600 unit with a G1 (1 in) port in G thread, fitted with an automatic drain on the filter bowl, the standard 40 um filter element, a low-pressure type regulator, an embedded square gauge reading in psi, and a reverse/check valve. The filter removes water and particulate before regulation, the regulator holds a stable downstream pressure, and the lubricator adds oil mist for downstream air tools and cylinders. At size 600 the bowls are aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT as order options), drain type, filter grade (40 um standard, 5 um with code W), gauge scale and reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm flow 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). The combination has no separate bracket code — the three units couple together with their own mounting hardware. 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, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF600-C2 filter, GR600-C2 regulator and GL600-C2 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds filtered, regulated and lubricated air to spray booths and air-assisted applicators on a vehicle paint line, with the automatic drain clearing condensate between shifts.
Prepares the air feeding carton sealers, case erectors and pneumatic diverters on a packaging conveyor line, keeping downstream cylinders and actuators supplied with clean, lubricated air.
Supplies the air circuit for workholding clamps and tool-change cylinders on a CNC machining centre, where the reverse/check valve helps hold the clamped state if upstream supply is interrupted.
Start with the size and port: 600 is the largest step in the GC range and carries a 1 in port, so match it against the air demand of the circuit - and remember flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type; if your line runs at standard shop pressures, the standard type may be the better match, and we can confirm the exact regulation range on request. The automatic drain (code A) bleeds condensate from the bowl without manual attention - choose manual or differential-pressure drain codes if you prefer a different regime. The 40 um element is the standard grade; specify W for the 5 um option where finer filtration is needed. The square gauge here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. Thread is G in this code, with PT as the standard and NPT available to order. A bracket is included, and the fitted reverse/check valve (code K) holds downstream pressure if the supply drops.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR600-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your application and operating pressure and we will confirm the sizing against the datasheet curves on request before you order.
The L is the regulator type code: this is the low-pressure type rather than the standard type. The exact regulation range for the low-pressure type is not published in the material we hold, so we confirm it on request. The unit also carries an automatic drain (A), a 40 um element, a square psi gauge (F2), G thread and a reverse/check valve (K).
