The AirTAC GC600-20G AirTAC F.R.L. Combination, G3/4, 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 GC600-20G is a genuine AirTAC three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is the size 600 unit with a G3/4 port, so it sits on a 3/4 in compressed-air line. The filter element is the standard 40 um grade and the bowl is drained manually, with the bowl in aluminium alloy at this size. The standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) and a round gauge scaled in psi is fitted so the set pressure can be read directly. 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 available in sizes 200, 300, 400 and 600, with a choice of port sizes, thread forms (PT standard; G and NPT as order options), drain types, filter grades (40 um standard, 5 um with code W) and gauge scales (MPa, psi or bar). Flow is published in the catalogue as curves rather than a single rated figure, so we 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.

Feeding spray-booth air lines where filtered, regulated and lightly oiled air reaches the paint guns and air-driven agitators, with the manual drain bled at the start of each shift.
Conditioning the 3/4 in main that runs pneumatic grippers, pushers and conveyor stops on a beverage filling line, keeping water and debris out of the valve manifold.
Preparing shop air ahead of a machining centre's pneumatic tool-change circuit and air clamps, with the regulator set to the clamp circuit pressure and read on the psi gauge.
Start with the size and port: GC600 carries the largest port in the family (3/4 in), and the size step up from GC400 exists to serve lines with higher air demand - match the port step to the flow your line needs, then ask us to confirm the flow curve against your consumption before ordering. Choose the drain type: this unit has a manual drain, which suits positions where an operator can bleed the bowl on a routine; if the drop point is unattended, the automatic or differential-pressure drain variants are the better decode. Filter grade is 40 um standard; specify the W code if the 5 um element is needed. Gauge scale is selectable (MPa, psi or bar) - this configuration carries the round gauge in psi. Thread is G (BSPP) here; PT is the standard form and G/NPT are order options. A mounting bracket is included.
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 curves in the catalogue, not as a single rated figure, so we do not quote a number. Tell us your line pressure and air consumption and we will confirm the flow figures from the datasheet for this exact unit on request.
The manual drain on this GC600-20G means an operator opens the drain to bleed collected water from the filter bowl as part of a routine. Choose manual where the unit is accessible and checked regularly; if the drop point is unattended or hard to reach, specify the automatic or differential-pressure drain variant instead.
