About the Airtac GC FRL Unit GC300C08MC1W
The GC family is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This GC300C08MC1W is size 300 with 1/4 in PT ports, a manual-drain filter bowl, the finer 5 um filter element (the W option) and a round MPa gauge on the regulator. On the line it strips water and fine particulate, holds the downstream pressure you set, and meters oil mist into the air feeding your tools and actuators.
It is a genuine AirTAC part. Max working pressure is 1.0 MPa (145 psi), the regulator adjustment range with manual drain is 0.05-0.9 MPa (7-130 psi), working temperature is -5 to 70 C non-freezing, and the 300-size filter and lubricator bowls are polycarbonate. The G series runs from size 200 to 600 with a choice of drain type, 40 um or 5 um filtration, gauge style and PT, G or NPT threads. Flow for this series is published as curves, not a single rating, so ask us and we will confirm the datasheet 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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-C0 filter, GR300-C0 regulator and GL300-C0 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
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.

Where the Airtac GC FRL Unit GC300C08MC1W Is Used
CNC fixture clamping circuit
Supplies the clamping cylinders on a machining-centre fixture: 5 um filtration protects the small pilot valves in the clamp manifold, the regulator holds clamp pressure, and the lubricator conditions the actuator air.
Lab automation air supply
Feeds pneumatics on an automated sample-handling bench where the 5 um element keeps solenoid valves clean, and the round MPa gauge gives operators a visible setpoint for repeat runs.
Assembly bench air tools
A workbench take-off for nutrunners and air ratchets: 5 um filtered air, regulated pressure read on the MPa gauge, and oil mist carried to the tools through the lubricator.
Is the Airtac GC FRL Unit GC300C08MC1W the Right Station?
Size 300 with 1/4 in PT ports is the mid step of the range; step up to size 400 or 600 for more flow, or down to size 200 at compact points of use. Manual drain means the bowl is emptied by hand - choose automatic or differential-pressure drain where the unit is hard to reach. The W in this code selects the 5 um element instead of the standard 40 um, the right call when small pilot valves or fine components sit downstream. The round gauge reads in MPa, and square-gauge or no-gauge variants exist. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves rather than a single rating, so ask us to confirm sizing against your pressure and flow requirements before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
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-C0 regulator with a GF300-C0 filter on that branch.
Airtac GC FRL Unit GC300C08MC1W FAQ
AirTAC publishes flow for this series as performance curves, not as a single rated figure, so we do not state a number here. Tell us your working pressure and the flow your circuit needs and we will confirm the right size from the datasheet on request.
Choose W when sensitive components such as pilot-operated valves, small cylinders or precision air tools sit downstream and need finer particulate removal. The standard 40 um grade suits general plant air and tool circuits. Both grades are catalogue options on this size 300 set.
