The AirTAC GC60020LF2GK AirTAC F.R.L. Combination, G3/4 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC60020LF2GK is an AirTAC GC600 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one piped set. This configuration is the size-600 unit with a G3/4 (3/4 in) port, the 40 um standard filter element and a differential-pressure drain on the filter bowl. The regulator is the low-pressure type, fitted with the embedded square gauge scaled in psi, and a reverse/check valve is fitted to hold the downstream circuit. Because this is the 600 size, the bowls are aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing); a mounting bracket is included.
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600, with port options, drain types (differential-pressure, automatic or manual), a 5 um filter element option, gauge scale choices and thread variants (PT standard; G and NPT as order options). Flow is published as curves rather than a single rated figure, so ask us to 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.

Installed at the take-off point of a factory compressed-air main, the unit cleans water and particulate from the 3/4 in supply, holds the header pressure the downstream circuit was set for, and carries oil mist into the plant's air tools and cylinders.
Mounted ahead of a packaging or conveyor line's valve bank, the combination keeps line moisture and debris out of the directional valves, gives operators a local regulated pressure with a psi gauge, and lubricates the actuators that cycle the line all shift.
For machine builders and retrofit work, a single three-unit set conditions the whole pneumatic circuit at the machine inlet: one filter, one regulator and one lubricator, with the included bracket fixing the assembly inside the machine's air-preparation cabinet.
Start with the size and port: the GC series steps through sizes 200, 300, 400 and 600, and this unit is the 600 with a G3/4 port - the largest step, chosen when the line and the required flow call for a 3/4 in connection. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. Then settle the decodable choices: drain type (differential-pressure as here, or automatic or manual), filter grade (40 um standard as here, or 5 um with code W), gauge scale (MPa, psi or bar - this unit carries the square gauge in psi), and thread (PT is the standard; G and NPT are catalogue options to order). A mounting bracket is included, and the low-pressure (L) regulator type is the right pick where the working pressure sits at the lower end of the range.
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 the GC series as curves rather than a single rated figure, so we do not quote one number here. Tell us your inlet pressure and the flow your circuit needs, and we will confirm the sizing from the datasheet curves on request before you order.
The L in the code GC60020LF2GK marks the low-pressure regulator type, selected where the working pressure sits at the lower end of the range; the exact range for this type is not published, so confirm it with us. The blank drain position means the differential-pressure drain is fitted as standard - it bleeds collected water as the pressure differential across the filter builds, with no operator attention needed.
