The AirTAC GC600-20 AirTAC F.R.L. Combination, PT3/4, Manual 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 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC600-20 is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate, a regulator holds downstream pressure steady, and a lubricator adds oil mist for air-powered tools and cylinders. This size-600 unit is fitted with a 3/4 in PT port, a manual drain on the filter bowl, the standard 40 um filter element, and an embedded square gauge reading in psi. Because it is the 600 size, the filter bowl is aluminium alloy, and a reverse/check valve is fitted to hold downstream pressure if the supply drops. A mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um filter element (code W), round external gauges, MPa/psi/bar gauge scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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 0.05 - 0.9 MPa (7 - 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 spray guns and air-assisted applicators on a paint line, where the filter strips water and grit, the regulator holds a steady gun pressure, and the lubricator mists oil to the air motors.
Supplying the pneumatic cylinders, clamps and vacuum generators on a carton-forming and sealing conveyor, with the check valve helping hold downstream pressure through supply dips.
Conditioning the shop air feeding a machining centre's pneumatic tool changer, clamps and chip-blow-off guns, with the 40 um element and manual drain suiting an attended cell.
Start with the port and size step: the 600 size carries a 3/4 in port and suits the higher-flow end of the range, but sizing should be checked against the flow curves rather than a single rating. Choose the drain type for the filter bowl: manual drain suits attended installations where an operator can bleed accumulated water, while automatic drain removes that task; the standard 40 um element handles general particulate, and the 5 um (W) option is there when finer filtration is needed. The gauge is the embedded square type reading in psi, with MPa or bar scales and an external round gauge available as options. Thread is PT as standard, with G (BSPP) and NPT as order options, and a reverse/check valve is fitted on this code. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your working pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet curves on request before you order.
The manual drain on the filter bowl means an operator opens the drain to release accumulated water and contaminants, which suits attended installations. Automatic drain is available as an option on this series if you want the bowl to discharge without operator involvement.
