The AirTAC GC30008MLC2WK AirTAC 3-Piece F.R.L., PT1/4, 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 PT1/4" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC30008MLC2WK is a three-piece AirTAC GC combination that joins a filter, a pressure regulator and a lubricator in one assembled set, so a single 1/4 in PT connection conditions compressed air completely: water and particles down to 5 um are removed, downstream pressure is held steady, and a fine oil mist is carried to the cylinders and air tools that follow. This size 300 unit has a manual drain on the polycarbonate filter bowl, a low-pressure regulator with a round psi gauge, a reverse (check) valve, and an included mounting bracket; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC300 series is offered in a range of port sizes and thread options (PT standard, with G and NPT available to order), with a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge style and scale, and standard or low-pressure regulation. Flow is published as curves rather than a single rated figure, so send us your application and we will confirm the sizing and full 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.

|---|---|
| 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). |
| 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. |
| (blank) | PT 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.

Feeds filtered, regulated and lubricated air to gripper cylinders and actuated tooling on assembly robots, holding supply pressure steady through repeated cycles.
Conditions the air feeding stoppers, pushers and sorting cylinders on a bottling or carton conveyor, with the oil mist keeping cylinder seals running smoothly.
Serves a bench drop where impact wrenches, ratchets and grinders run off a 1/4 in line; the 5 um element and oil mist protect the tools between services.
Choose the size by port and duty: 200, 300, 400 and 600 step up in port and capacity, and this 300 unit takes a 1/4 in PT connection. Decide the drain first - manual (this unit) needs periodic bowl draining, while automatic and differential-pressure drains suit unattended installations. Pick the filter grade: 40 um is standard and 5 um (this unit, code W) protects finer components. The regulator here is the low-pressure type; we confirm its adjustment range from the datasheet on request. Gauges can be embedded square or external round with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G and NPT as orderable options, the mounting bracket is included, and the reverse (check) valve fitted here is also an orderable choice. Bowls are polycarbonate at this size (size 600 uses aluminium alloy).
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 there is no one l/min or SCFM number we can quote. Send us your line pressure, port size and downstream demand and we will confirm the sizing and full datasheet figures on request before you order.
The M in the code sets a manual drain: the filter bowl is emptied by hand, which suits attended cells and shorter runs. If the unit will sit unattended, order the same GC300 configuration with an automatic (A) or differential-pressure drain instead - the drain choice is a decodable option across the GC series.
