The AirTAC GC600-20 AirTAC F.R.L. Combination PT3/4 5um Auto Drain 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 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built as one coordinated set. This 600-size unit carries PT3/4 ports and is configured with a 5 um filter element (code W) and an automatic drain, so collected condensate is expelled without manual attention. The bowl on the filter section is aluminium alloy, as is standard for the 600 size. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the set includes an embedded square gauge reading in psi. A reverse/check valve is fitted, and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port options, drain types, filter grades, gauge styles and scales selectable per code. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the 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. 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: GF600-20 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.

Feeding filtered, regulated and lubricated air to pneumatic presses and clamping fixtures on a stamping line, where the 3/4 in port serves a main drop and the automatic drain keeps condensate off the valves.
Supplying clean, pressure-stabilised, oil-misted air to robot end-of-arm grippers and tool changers, with the 5 um element protecting fine pilot valves in the cell.
Conditioning the supply to a cartoning or wrapping machine's cylinder bank, where the lubricator maintains seal life and the psi gauge lets operators verify set pressure at a glance.
Start with the port size: this unit steps up to 3/4 in (PT) on the 600 frame, the largest in the GC range, so match it to the line size and the air demand of the downstream circuit. For the filter section you can choose the 40 um standard element or this 5 um fine grade (code W) where downstream valves and cylinders need cleaner air. Drain choice is differential-pressure (default), automatic (this unit) or manual. The regulator can be ordered with an embedded square gauge or an external round gauge, in MPa, psi or bar scale, and a reverse/check valve is optional. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A bracket is included on this code.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so please ask us to confirm the flow data against your application before 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 the GC series as performance curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the datasheet flow data for this exact configuration on request.
The automatic drain expels collected condensate on its own, which suits unattended or hard-to-reach installations; the alternatives are the differential-pressure drain (default) or a manual drain. The 5 um element (code W) is the fine filtration option instead of the 40 um standard grade, chosen when downstream valves and cylinders need cleaner air.
