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 GC600-20 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 600 unit has PT3/4 ports, so it suits a 3/4 in compressed-air main. The filter element is the standard 40 um grade for water and particulate removal, with a manual drain you operate by hand, and the filter bowl on this size is aluminium alloy. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), read on the fitted round gauge scaled in psi, and a reverse/check valve is fitted to hold downstream pressure. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, plus options such as a 5 um filter element (code W), automatic or differential-pressure drain, gauge scale in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rated figure, 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 0.05 - 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 filtered, regulated and lubricated air to machining centres and lathes, where the 40 um element removes water and swarf-carrying particulate and the lubricator mists oil to spindle-adjacent air tools and clamping cylinders.
Supplying a 3/4 in main serving air cylinders and impact tools along an assembly conveyor, with the regulator holding a steady set pressure and the check valve helping hold downstream pressure if the supply dips.
Conditioning plant air at the point of entry to case packers, labelers and carton-sealing equipment, where clean, correctly lubricated air keeps valve spools and cylinders moving shift after shift.
Start with the port step: size 600 with PT3/4 ports is the largest G-series frame, so match it to your main line size and the flow your actuators and tools actually draw - larger sizes carry larger ports and more flow. Choose the drain to suit access: this unit has a manual drain, which is simple and reliable but needs someone to open it periodically; automatic and differential-pressure drain options exist if the unit will sit where nobody passes. The standard 40 um element suits general plant air; specify the 5 um W-grade element where downstream equipment needs finer filtration. The fitted round gauge here reads in psi; MPa and bar scales are also available. PT thread is the standard; G (BSPP) and NPT are order options.
Because flow is published as curves rather than a single rating, we do not quote a rated flow number for this unit. Send us your application details and we will confirm sizing against the datasheet curves 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 GR600-20 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 state a rated flow, Cv or SCFM number. Tell us your line pressure and the air demand of your equipment, and we will confirm the flow figures from the datasheet on request before you order.
The M in the code GC60020MC2K specifies a manual drain on the filter bowl: someone opens it periodically to expel collected water, which suits attended installations. If the unit will be mounted where nobody passes regularly, the same series can be ordered with an automatic drain (code A) or the default differential-pressure drain instead.
