The AirTAC GC600-20ALC2GK AirTAC F.R.L. Combination, G3/4, Low-Pressure 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 PT3/4" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20ALC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, so compressed air is cleaned of water and particulate, held at a set working pressure, and carries oil mist to downstream pneumatic components. This 600-size unit is built around a G3/4 port with G thread, and the configuration is fully decoded from the code: automatic drain on the filter bowl, 40 um standard filtration, low-pressure regulator type, a round gauge with psi scale fitted, a reverse/check valve on the regulator, and a mounting bracket included. The 600-size bowls are aluminium alloy, and maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with a choice of drain type, 40 um or 5 um (W) filtration, gauge type and scale, thread option and reverse valve. Because flow is published as curves rather than a single rated figure, we confirm flow and other datasheet figures for your application on request.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF600-20 filter, GR600-20 regulator and GL600-20 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.

At the main air drop feeding a CNC machining cell, the three-unit set removes condensate and swarf-carrying particulate, holds a steady working pressure for clamps and tool-change cylinders, and feeds oil mist to the actuators.
On a carton-forming and sealing line, the combination conditions the supply to case-packing cylinders and vacuum generators: clean, dry air through the 40 um element, regulated pressure for consistent jaw action, and lubrication for high-cycle cylinders.
In a heavy-vehicle service bay, the unit conditions shop air feeding impact wrenches, air jacks and tyre-caging stations, with the automatic drain clearing condensate from the aluminium bowl without a manual bleed routine.
The GC series lets you step through sizes 200, 300, 400 and 600, each with its own port range, so you match the unit to the flow your line needs; this 600-size, G3/4 configuration sits at the top of the range for larger air supplies. Where a regulator is part of the set, you choose drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with W), gauge style and scale (MPa, psi or bar), and whether a reverse/check valve is fitted; this unit carries an automatic drain, a round psi gauge and a check valve. Thread is PT as standard, with G (BSPP) and NPT as order options - this unit is ordered with G thread. A mounting bracket is included.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The low-pressure regulator type in this code has an adjustment range that is not published in the sheet we work from - confirm the exact range with us when ordering.
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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for this 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 pressure and the flow your application needs, and we will confirm the correct size against the datasheet curves on request before you order.
The L code marks the low-pressure version of the regulator in this set, intended for lower working-pressure circuits than the standard type. The exact adjustment range for the low-pressure type is not published in the sheet we work from, so confirm the range you need with us; the unit's maximum inlet pressure remains 1.0 MPa (145 psi).
