About the Airtac GC FRL Unit GC300C08C1K
GC300C08C1K 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 filter removes water and particulate with the standard 40 um element and a differential-pressure drain; the regulator holds your set downstream pressure over a 0.15-0.9 MPa (20-130 psi) adjustment range; the lubricator adds oil mist for downstream cylinders and air tools. The C1 option adds an external round gauge scaled in MPa, and the K option fits a reverse (check) valve that holds downstream pressure if the upstream supply drops. 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 GC300C08C1K Is Used
CNC machining center air supply
Feeds filtered, regulated and lubricated air to the tool-clamp cylinders, chip conveyor and coolant-valve actuators on a machining center, with the check valve holding the clamp circuit if shop air dips.
Packaging line case sealers
Conditions the air feeding carton-sealer and case-erector cylinders on a packaging line: water and debris removed, pressure held steady, oil mist carried to the cylinder seals.
Pilot-air header on a bottling filler
Sits ahead of the pilot-valve manifold on a rotary filler, delivering clean 40 um air at a set pressure, with the reverse valve keeping the manifold charged during brief supply interruptions.
Is the Airtac GC FRL Unit GC300C08C1K the Right Station?
This GC300 code is built for PT1/4 lines. Step down to GC200 (1/8 or 1/4 in.) or up to GC400 (3/8 or 1/2 in.) and GC600 (3/4 or 1 in.) to match pipework and required flow. Choose the drain: differential-pressure (this code), automatic (A) or manual (M); the regulator span follows the drain type - 0.15-0.9 MPa (20-130 psi) for differential-pressure and automatic, 0.05-0.9 MPa (7-130 psi) for manual. Pick the 40 um standard element or the 5 um (W) fine grade, a round (C) or square (F) gauge with MPa (1), psi (2) or bar (3) scale, and the K reverse valve. Thread is PT as standard; G (BSPP) and NPT are orderable options. Flow is published as curves, not a single rating, so have us confirm sizing against your application 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 GC300C08C1K FAQ
AirTAC publishes flow for the GC300 series as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and downstream air demand and we will confirm the correct size and share the datasheet on request.
K means a reverse (check) valve is fitted: if upstream supply is lost, the valve holds pressure on the downstream side so actuators and clamps do not collapse. Without K the unit has no check valve. The rest of the code reads: GC three-unit F.R.L., 300 size, PT1/4 port, differential-pressure drain, 40 um element, round MPa gauge.
