The AirTAC GC30008MLF2GK AirTAC F.R.L. Combination G1/4 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 PT1/4" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC30008MLF2GK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit, giving a single supply point that removes water and particulate, sets and holds working pressure, and adds lubricating oil mist for downstream air tools and cylinders. This size 300 configuration is ported G1/4 (1/4 in), uses the standard 40 um filter element, and has a manual drain on the filter bowl, so condensate is emptied by opening the drain when servicing. The regulator is the low-pressure type and carries an embedded square gauge scaled in psi; a reverse/check valve is fitted to hold downstream pressure if the upstream supply drops, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with a choice of ports and thread options, drain types, filter grades (40 um standard, 5 um optional) and gauge scales. Flow figures for the series are published as curves rather than a single rated number, 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.

|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (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. |

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: GF300-08 filter, GR300-08 regulator and GL300-08 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 filtered, regulated and lubricated supply point feeding pneumatic clamps, tool-change cylinders and air blow-off stations on a machining centre.
Conditioning the air that drives the cylinders and actuators on a packaging conveyor, with the check valve holding settings through brief supply dips.
A wall-mounted F.R.L. ahead of impact wrenches, air ratchets and blow guns, keeping tools lubricated and working pressure set at the point of use.
Start with the port and size: GC300 is the 300 frame with a 1/4 in port here, and larger sizes (400, 600) carry larger ports and more flow capacity, so step up if your demand is high. Choose the drain to match maintenance habits: manual (this unit, code M) needs periodic draining, automatic (A) drains condensate on its own, and differential-pressure is the catalogue default. Filter grade is 40 um standard; specify W for the 5 um element where finer filtration is needed. The embedded square gauge is standard and can be scaled in MPa, psi or bar (this unit is psi); an external round gauge is optional. Thread is G (BSPP) here; PT is the standard thread and G or NPT are catalogue options to order. A bracket is included on this unit, and the reverse/check valve (K) protects downstream pressure against supply dips. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. 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 GR300-08 regulator with a GF300-08 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, Cv or SCFM number. Tell us your application and we will confirm the sizing from the datasheet on request.
This configuration uses a manual drain (code M): condensate collected in the filter bowl is emptied by opening the drain during servicing. If you prefer the bowl to discharge condensate without attention, the same series is available with an automatic drain (code A); the catalogue default is a differential-pressure drain. Ask us to confirm the variant you need.
