The AirTAC GC600-20 AirTAC F.R.L. Combination, PT3/4 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 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 3/4-inch (PT3/4) unit. It cleans compressed air of water and particulate down to the standard 40 um grade, regulates downstream pressure across the 0.05-0.9 MPa (7-130 psi) adjustment range with the standard regulator type, and adds oil-mist lubrication for downstream air tools and cylinders. This configuration uses a manual drain on the filter bowl, and the round pressure gauge fitted to this code reads in psi. Because this is the 600 size, the pressure bowls are aluminium alloy rather than polycarbonate.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual draining, 40 um standard or 5 um (code W) filtration, and PT, G or NPT threads. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published by the manufacturer as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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.

Feeds clean, regulated and lubricated air to the clamping fixtures, tool changers and actuated gates on a machining centre, with the 3/4-inch port matching the main drop feeding the cell.
Conditions the air feeding carton-forming cylinders, sealing jaws and case-erector valves on a packaging line, keeping water and debris out of the valves while the lubricator mist protects the cylinders.
Supplies regulated, lubricated air at the service-bay drop for impact wrenches, tyre chucks and air jacks, with the psi gauge letting technicians set and read tool pressure directly.
Start with the port step: the GC range runs 200/300/400/600 with ports from 1/8 to 1 inch, so pick the size whose flow curve covers your demand rather than matching pipe size alone - we can check the curve against your consumption if you send the figures. On draining, this code is manual: someone opens the drain periodically, which suits attended installations; choose automatic or differential-pressure draining where the unit is hard to reach. Filtration is the 40 um standard grade; specify 5 um (code W) where downstream equipment needs finer air. The gauge on this unit is a round external type reading psi; embedded square gauges and MPa/bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so we do not quote a rated flow. Ask us to confirm the flow data against your application 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 the GC series as performance curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet and the flow curve for this 3/4-inch unit on request.
The M in the code GC600-20MC2 specifies a manual drain: the filter bowl is emptied by hand at intervals, which suits installations that are checked regularly. The catalogue also offers automatic and differential-pressure draining on GC units if you would rather not rely on manual draining.
