The AirTAC AirTAC GC600C20LF2G 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a separate pressure regulator and a separate oil-mist lubricator, set up as one air-treatment train. This configuration, GC600C20LF2G, is the 600 size with a G3/4 (3/4 in) port and G thread. The filter element is the standard 40 um grade and its bowl drains by differential pressure, so condensate is expelled as the pressure differential across the element builds. The regulator is the low-pressure type and carries a fitted embedded square gauge scaled in psi. The bowls on the 600 size are aluminium alloy, and a mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port options from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual bowl drain, an optional 5 um filter element, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding spray guns and air-assisted applicators on a vehicle refinish line, where the three-stage train removes water and particulate at 40 um, holds a steady low-pressure setting at the gun and delivers a fine oil mist to keep the tool running smoothly.
Supplying the cylinder and valve circuits on a carton-forming and sealing line, where the filter protects the valves from condensate and swarf, the low-pressure regulator holds a consistent setting for gentle clamping, and the lubricator mists the cylinder seals.
Treating the air feeding workholding clamps and swing cylinders on a CNC machining cell, where clean, regulated and lubricated air keeps clamp force repeatable through the shift and the square psi gauge gives the operator a visible setting reference.
Start with the size and port: the 600 size in this code gives a G3/4 (3/4 in) port, the largest step in the GC range, so match it against the pipe bore and the air demand of the machine it feeds. The drain on the filter bowl is differential pressure by default; automatic or manual drain versions can be ordered instead if the installation cannot rely on differential-based expulsion. The filter grade here is the standard 40 um; specify the W option if the application needs 5 um filtration. The fitted square gauge is scaled in psi, and MPa or bar scales are available as alternatives. Thread is G in this code; PT is the standard and G or NPT are catalogue options to order. A mounting bracket is included with this unit.
One honest note on sizing: flow for the GC series is published as curves, not as a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing against the datasheet before you order.
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 the GC series as curves rather than a single rated figure, so we do not state a flow number for this unit. Tell us your line pressure, port size and the air demand of the equipment, and we will confirm the flow and sizing against the datasheet on request before you order.
The trailing G means this unit is specified with G (BSPP) threads on its 3/4 in ports. PT is the standard thread for the GC series, and G or NPT are catalogue options that are ordered as part of the model code, so specify the thread you need when ordering rather than adapting afterwards.
