The AirTAC GC600-25 AirTAC F.R.L. Combination Unit, PT1 Port 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 PT1" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC600-25 is a three-piece F.R.L. combination from AirTAC's G series: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit. This configuration is the size 600 body with a PT1 (1 in) PT-thread port, the fine 5 um filter element (code W), a manual drain on the filter bowl, the low-pressure type regulator, an embedded square gauge scaled in psi, a reverse/check valve fitted, and the mounting bracket included. It prepares compressed air in one pass: water and particulate are drained off at 5 um filtration, downstream pressure is set on the regulator, and oil mist is metered into the air line to lubricate connected tools and actuators.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G (BSPP) and NPT thread variants to order, manual, automatic or differential-pressure drains, 40 um standard or 5 um fine filtration, and gauge scale choices. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for your application before ordering.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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: GF600-25 filter, GR600-25 regulator and GL600-25 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 tool-changer and clamping actuators on a machining centre, with the 5 um element protecting tight-tolerance valves on a 1 in main drop.
Installed at the drop point feeding spray booths and air-driven agitators, where the fine filter grade, set regulator pressure and oil mist keep finishing equipment running consistently.
Supplies filtered, regulated and lubricated air to the pneumatic pushers and stopper cylinders along a filling and capping conveyor, with the check valve holding set pressure in the branch.
Start with the port step: this unit is size 600 with a PT1 (1 in) PT-thread port, the largest in the G series - step down to GC300 or GC400 if your line runs smaller ports and lower air demand, since flow is published as curves rather than a single rating, we will confirm the right size against your application on request. Drain choice matters: this unit has a manual drain (code M), which suits attended installations where an operator bleeds the bowl; choose automatic or differential-pressure drain codes if the unit sits where nobody drains it. The 5 um element (W) is the finer grade over the 40 um standard - pick it where downstream equipment tolerates less particulate.
This is the low-pressure type regulator (code L); its adjustment range is not published in the material we hold, so confirm the set pressure with us. The square gauge here is scaled in psi (code 2); MPa and bar scales are available. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the 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 GR600-25 regulator with a GF600-25 filter on that branch.
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing against the datasheet curves on request before you order.
The M in the code GC60025MLF2WK specifies a manual drain: the filter bowl is bled by hand, which suits installations where an operator is present. The W specifies the 5 um fine element instead of the 40 um standard, chosen where downstream valves and tools need finer particulate removal. Automatic and differential-pressure drains, and the 40 um grade, are available on other codes in the same size.
