The AirTAC GC30008MLF2WK AirTAC F.R.L. Combination 1/4 in PT 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 GC30008MLF2WK 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 package. This 300-size unit is fitted with a PT1/4 (1/4 in) port, a 5 um filter element with manual drain, a low-pressure regulator with an embedded square gauge scaled in psi, a reverse/check valve, and a mounting bracket. The polycarbonate bowls suit the -5 to 70 C non-freezing operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade (40 um standard, 5 um with W) and gauge scale. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing 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.
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 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. |
| 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. |
| 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: 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 directional valves and cylinders on automated machinery, with the low-pressure regulator set to the circuit's working pressure and the 5 um element protecting fine valve internals.
Supplies conditioned air to packaging, labelling and cartoning lines where the lubricator maintains a consistent oil mist for air motors and grippers, and the manual drain is bled during scheduled changeovers.
Installed at a workshop air drop serving hand-held pneumatic tools and small clamping fixtures, combining water and particulate removal, low-pressure regulation with a psi gauge, and tool lubrication in one assembly.
Size the unit by the port and flow step: 200, 300, 400 and 600 move up in port and capacity, with this 300 size carrying PT1/4. Choose the drain to match the installation: manual drain (as fitted here) needs an operator to bleed the bowls, while automatic and differential-pressure drains discharge without attention. Filter grade is 40 um standard or 5 um (code W) for finer protection, as on this unit. The gauge is an embedded square type as standard with an external round gauge optional, in MPa, psi or bar scales. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Because flow is published as curves rather than a single rated figure, 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 performance curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code specifies manual drains, which an operator opens to release collected water; this suits attended installations and scheduled maintenance routines. The GC family is also available with automatic or differential-pressure drains that discharge without operator attention, and we can quote those variants if your application is unattended.
