The AirTAC AirTAC GC600-25G F.R.L. Three-Unit, G1, 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 PT1" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC600-25G is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one coordinated set for compressed air. This configuration is built around a G1 (1 in) port with G thread, the largest step in the GC range, so it suits a main air line rather than a branch drop. The filter stage carries the standard 40 um element with a manual drain and an aluminium alloy bowl, which is the bowl material used at size 600. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi; a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port steps from 1/8 in up to 1 in, drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT as the standard thread with G and NPT as order options. Flow is published as curves rather than a single rated figure, so ask us to 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. 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |

| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |

| (blank) | Filtering grade 40 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. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Installed at the 1 in main drop feeding an assembly hall, the set cleans water and particulate from the plant air, holds a steady low-pressure supply to the tools and carries a fine oil mist to keep air impact wrenches and nut runners lubricated through the shift.
Mounted on the supply to a bottling hall conveyor system, the filter stage removes condensate and debris before the air reaches cylinders and grippers, the low-pressure regulator holds a stable setting for gentle product handling, and the lubricator mists the air for the line's pneumatic actuators.
Fitted where a fabrication shop's 1 in ring main drops to tool stations, the unit conditions the air for grinders, chippers and clamps: the 40 um element and manual-drain bowl catch water and swarf, the regulator sets the working pressure at the station, and the lubricator feeds the shop's air tools.
Start with the port step: size 600 with a 1 in port is the top of the range, so match it against the air demand of the line it will feed; smaller sizes (200/300/400) step down in port and physical size. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering. For the drain, this unit is manual: someone opens the drain periodically, which suits attended installations; automatic and differential-pressure drains are available in the family where unattended purging is preferred. The standard element is 40 um; specify code W for the 5 um grade if downstream equipment needs finer filtration. The gauge here is the embedded square type scaled in psi; MPa and bar scales and an external round gauge are alternatives. Thread is G in this code; PT is the standard and NPT can be ordered. A bracket is included with this set.
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 this family as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Size 600 with a 1 in port is the largest step in the GC range, which is usually the tell for a main-line unit, but the right check is against your actual demand. Send us your application details and we will confirm the flow figures from the datasheet on request before you order.
This code carries drain type M, a manual drain: the aluminium alloy bowl on the filter stage is emptied by opening the drain periodically, which suits installations where someone is present to do it. If the set will sit unattended, the GC family also offers automatic (code A) and differential-pressure (blank) drains, and the regulator adjustment range depends on the drain type fitted, so tell us your preference and we will confirm the right variant.
