The AirTAC AirTAC GC600C25C2WK F.R.L. Combination, PT1 in, 5 um 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 GC600C25C2WK is a three-piece F.R.L. combination unit: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is built around a 1 in PT port for high-flow compressed-air circuits, with the filter element set to the finer 5 um grade for cleaner air downstream. The filter bowl uses a differential-pressure drain, the regulator is the standard type with a round external gauge scaled in psi, and a reverse/check valve is fitted. At size 600 the bowls are aluminium alloy, and the unit includes a mounting bracket.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in up to 1 in. Across the series you can order differential-pressure, automatic or manual drains, 40 um or 5 um filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, 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 machine-tool builder fits this 1 in F.R.L. at the main air drop of a CNC machining centre, where the 5 um element protects clamping valves and the regulator holds a steady setting for fixture cylinders while the lubricator feeds actuation air.
On a bottling line, the combination unit conditions the supply feeding conveyor gate cylinders and stopper actuators: the filter sheds water and fine dirt, the regulator keeps the pressure the line was set up with, and the lubricator mists oil for the cylinders.
A commercial truck workshop installs this unit at the head of its 1 in tool-air ring main, so impact wrenches and air ratchets draw filtered, regulated and lubricated air, with the check valve holding the line against backflow when the compressor unloads.
Start with the size and port: the 600 series with a 1 in PT connection suits larger distribution lines, and the right step depends on the flow your circuit needs rather than the pipe alone. Choose the drain type next: differential-pressure (as fitted here) drains automatically as flow passes, automatic drains on a timer-like cycle, and manual drains for infrequently visited installations. Filter grade is 40 um standard or 5 um (this unit carries the W option) where finer particulate removal matters. Gauge style is an embedded square gauge or an external round gauge, with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket can be included or omitted. 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-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your operating pressure and the flow your circuit needs, and we will confirm the sizing against the datasheet on request before you order.
The W in the code GC600C25C2WK selects the finer 5 um filtration instead of the 40 um standard, which suits circuits with sensitive valves or tools downstream. The C2 selects the external round gauge scaled in psi; the embedded square gauge is the standard option, and MPa or bar scales can be ordered instead.
