The AirTAC GC600-25G AirTAC F.R.L. Combination, G1 (1 in) 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-25G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This size 600 configuration carries a G1 (1 in) G-thread port, a 5 um filter element (code W), a differential-pressure drain on the filter bowl, a low-pressure type regulator, a reverse/check valve (code K) and a round gauge reading in psi. It filters water and particulate from compressed air, holds a set downstream pressure and adds oil mist to the air line in a single assembly.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include thread type (PT standard, G or NPT to order), drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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. 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

Mounted at the drop from a plant air main, the unit cleans, regulates and lubricates the air feeding an entire work cell, with the 5 um element and check valve protecting everything downstream.
Feeding the cylinder and actuator circuits of a packaging or conveyor line, it keeps supply pressure steady for consistent clamp and push strokes while oil mist lubricates the valves and cylinders.
Installed ahead of clamping fixtures or machine tool air circuits, the low-pressure type regulator holds a controlled setting for sensitive clamping while the filter removes water and wear particles.
Size 600 with a G1 (1 in) port is the largest step in the GC range; step down to 200/300/400 with smaller ports if your line flow is modest. The 5 um element (code W) suits air that is already reasonably clean or tools sensitive to finer particles; the 40 um standard element suits general plant air. The differential-pressure drain bleeds the bowl automatically as pressure drops across the element, with no timer or operator action.
The low-pressure type regulator is the choice for circuits that must not run at standard downstream settings; the round psi gauge gives direct local reading. G (BSPP) thread is an order option against the PT standard, and the mounting bracket is included. Because flow is published as curves and not a single rating, 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 GR600-25 regulator with a GF600-25 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and required air consumption and we will confirm the sizing from the datasheet on request before you order.
The L code makes this a low-pressure type regulator, intended for circuits that run below standard downstream settings; the exact range is not published, so we confirm it on request. The K code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is lost. The W code is the 5 um filter element, and the round gauge reads in psi.
