About the Airtac GC FRL Unit GC300C08C1WK
GC300C08C1WK is a three-piece AirTAC G-series F.R.L. combination: a separate air filter, pressure regulator and lubricator, assembled for 1/4 in. PT pipework. The W option fits the fine 5 um filter element with a differential-pressure drain; the regulator holds your set downstream pressure over a 0.15-0.9 MPa (20-130 psi) range; the lubricator adds oil mist for downstream actuators. The C1 option adds an external round gauge scaled in MPa, and the K option fits a reverse (check) valve that keeps downstream pressure in place if the supply fails - useful for clamps and holding circuits. Compressed air is the only medium.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with ports from 1/8 in. to 1 in. and PT, G (BSPP) or NPT threads. On the 300 size the filter and lubricator bowls are PC (polycarbonate). Operating temperature is -5 to 70 C (non-freezing) and maximum working pressure is 1.0 MPa (145 psi). Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and the full datasheet 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 GC300C08C1WK Is Used
Power clamps on welding fixtures
Feeds swing clamps and edge clamps on a robotic welding fixture; the check valve keeps clamps engaged if plant air is lost mid-cycle, while the 5 um element protects the clamp internals.
Air-operated process valves
Conditions the actuator air for diaphragm and ball valves on a process line, holding a stable set pressure to the positioners and retaining the actuator signal through brief supply dips.
Paint line spray-gun supply
Filters, regulates and lubricates the air to spray guns and air drives in a finishing booth, with the fine element helping keep the air clean enough for consistent finish work.
Is the Airtac GC FRL Unit GC300C08C1WK the Right Station?
This GC300 code suits PT1/4 lines; GC200, GC400 and GC600 cover other ports and larger or smaller duties. Here you have the 5 um fine element (W), the round MPa gauge (C1) and the reverse valve (K); drop the W for the 40 um standard grade or the K if you do not need pressure retention. Drain is differential-pressure; automatic (A) and manual (M) variants exist, with the regulator span at 0.15-0.9 MPa (20-130 psi) for differential-pressure and automatic, 0.05-0.9 MPa (7-130 psi) for manual. A square (F) gauge with MPa, psi or bar scale is also available. Thread is PT as standard; G (BSPP) and NPT are orderable options. Flow is published only as curves, so ask us to confirm sizing 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 GC300C08C1WK FAQ
There is no single rated-flow figure to quote: AirTAC publishes GC300 performance as curves. Share your line pressure and the air demand of your equipment and we will confirm the right size and send the datasheet on request.
W fits the 5 um fine filter element instead of the standard 40 um, giving cleaner air to sensitive equipment. K fits a reverse (check) valve, so if upstream air fails the downstream circuit holds its pressure instead of venting back through the unit. Both sit inside the same three-piece F.R.L. on a PT1/4 connection.
