About the Airtac GC FRL Unit GC300C08MC1WK
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 GC300C08MC1WK is size 300 with 1/4 in PT ports, a manual-drain filter bowl, the finer 5 um element (W), a round MPa gauge on the regulator and a reverse (check) valve fitted (K). On the line it removes water and fine particulate, holds the downstream pressure you set, meters oil mist to the actuators, and blocks backflow through the set.
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 GC300C08MC1WK Is Used
Robotic weld cell grippers
Air for the gripper cylinders on a weld-cell robot: 5 um filtration protects the valve pack, regulated pressure holds grip force, and the check valve stops backflow through the set when the cell is isolated.
Fleet workshop tire bay
Feeds a tire-changer and impact-gun bay in a truck fleet workshop: 5 um filtered, regulated and lubricated air, with the check valve holding the downstream circuit if the compressor unloads.
Bench pneumatic press feed
Supplies a small bench pneumatic press: fine 5 um air, downstream pressure set on the MPa gauge, oil mist carried to the cylinder, and reverse-flow protection built into the set.
Is the Airtac GC FRL Unit GC300C08MC1WK the Right Station?
Size 300 with 1/4 in PT ports is the mid step of the range; go to size 400 or 600 for more flow, or size 200 for compact points of use. Manual drain suits attended installations; select automatic or differential-pressure drain for hard-to-reach mounts. This code combines both options on the element and the regulator: W for the 5 um grade and K for the fitted reverse (check) valve. The round gauge reads in MPa, with square-gauge and no-gauge variants available. Thread is PT as standard, and G (BSPP) or NPT are catalogue options. Flow is published as curves rather than a single rating, so send us your pressure and flow requirements and we will confirm sizing from the datasheet before you order.
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 GC300C08MC1WK FAQ
Flow for the G series is published as performance curves, not as one rated number, so we do not quote a figure on this page. Share your operating pressure and required flow and we will confirm the correct size and datasheet values on request.
W selects the 5 um filter element instead of the standard 40 um grade, and K means a reverse (check) valve is fitted so air cannot flow back through the set. Drop either letter to order the configuration without that option.
