The AirTAC AirTAC GC600C20MLC2 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC600C20MLC2 is a three-unit F.R.L. combination that brings together a separate air filter, a pressure regulator and an oil-mist lubricator, so one assembly cleans the compressed air, holds the working pressure steady and adds lubricating mist for downstream tools and cylinders. This 600-size unit is built around a 3/4 in PT port, uses the standard 40 um filter element, and is fitted with a manual drain on the filter bowl. The regulator is the low-pressure type, and the round pressure gauge supplied with this code reads in psi. At size 600 the filter bowls are aluminium alloy rather than polycarbonate, and 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 options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, a 5 um filter element option, gauge scale choices, and G or NPT thread variants to order. Flow is published in the AirTAC 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 0.15 - 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-C2 filter, GR600-C2 regulator and GL600-C2 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.

A body shop's spray-booth supply run needs air that is free of water and particulate, held at a stable low working pressure for the atomising regulators, and lightly oiled where the plant still runs lubricated spray guns and air motors. A three-unit F.R.L. at the booth inlet does all three jobs in one assembly, and the 3/4 in port matches the branch feeding several booths.
Mechanical stamping presses and coil-feed lines run cylinders and air counters that need clean, moisture-free air at a steady set pressure, plus mist lubrication for the valves and cylinders on older equipment. A GC combination mounted at the press drop, with the bracket on the machine frame, keeps the whole circuit supplied from one service point.
Packaging machines with pneumatic actuators, grippers and glue-head cylinders draw from a shared 3/4 in header. A filter-regulator-lubricator set at each machine's take-off removes water carried over from the compressor room, sets the machine's working pressure with the psi gauge visible to the operator, and mists the cylinders and valves that are specified for lubricated air.
Start with the port and size: this code is the 600 size on a 3/4 in PT port, the largest step in the GC range, so choose it when the line's required flow points to the top of the series - we will confirm the exact flow from the catalogue curves before you order. The filter here is the standard 40 um grade; if the application needs finer filtration, the 5 um (W) element is the option to ask about. Drain choice matters: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl, while automatic and differential-pressure drains suit unattended lines. The regulator in this code is the low-pressure type, intended for circuits that work below the standard regulator band - its exact adjustment range is not published in the catalogue, so confirm it with us. The gauge fitted reads in psi; MPa and bar scales are the other options. Thread is PT as standard, with G (BSPP) and NPT available as order options, and 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-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves in the catalogue, not as a single rated number, so we do not quote a rated flow figure for this unit. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing against the datasheet curves on request before you order.
The M in this code specifies a manual drain on the filter bowl: condensate collects in the bowl and an operator opens the drain to release it, which suits installations that are checked regularly. If the unit will sit on an unattended line, ask about the automatic (A) or differential-pressure (standard, blank) drain variants instead. Note that the regulator adjustment range differs by drain type on the standard regulator; this code is the low-pressure type, and we confirm its exact range on request.
