About the Airtac GC FRL Unit GC300C10AC1K
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator that together clean, regulate and lubricate compressed air. GC300C10AC1K is a 300 size set with PT 3/8 in. ports, an automatic drain on the filter bowl, the standard 40 um filter element, an external round pressure gauge on the MPa scale, and a reverse (check) valve fitted. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family is offered in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in., drain options (differential-pressure, automatic or manual), 40 um or 5 um filtration, round or square gauges in MPa, psi or bar scales, G (BSPP) and NPT thread options, and an optional check valve. The filter and lubricator bowls in the 300 size are polycarbonate (PC). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet for your application.

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-C1 filter, GR300-C1 regulator and GL300-C1 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 GC300C10AC1K Is Used
CNC machining center air supply
Feeds filtered, regulated and lubricated air to tool-clamp and pallet-change cylinders on a CNC machining center, with the fitted check valve blocking reverse flow in the downstream circuit.
Cartoning and case-packing line
Conditions supply air for the pick-and-place cylinders and vacuum generators on a cartoning line; the automatic drain clears collected water without operator rounds.
Automotive assembly cell
Prepares shop air for impact wrenches and pneumatic fixtures at an assembly cell, keeping the regulator setting steady and the tools oiled through the shift.
Is the Airtac GC FRL Unit GC300C10AC1K the Right Station?
Step through the GC family by size: 200, 300, 400 and 600 cover ports from 1/8 to 1 in., so match the 300 size and PT 3/8 in. port to your line and the flow you need. Drain choice matters: differential-pressure is the default, automatic (as here) clears the bowl on its own, and manual-drain versions widen the regulator adjusting range to 0.05-0.9 MPa (7-130 psi); with this automatic-drain set the adjusting range is 0.15-0.9 MPa (20-130 psi). Filtration is 40 um standard or 5 um with the W option; the gauge here is a round external type on the MPa scale, with psi or bar scales available. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C10AC1K FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Send us your application details and we will confirm the flow curve and sizing from the datasheet on request.
K means a reverse (check) valve is fitted: air flows downstream in one direction and reverse flow back through the set is blocked. The rest of the code decodes as automatic drain (A), round gauge (C) on the MPa scale (1), in the 300 size with PT 3/8 in. ports and the standard 40 um element.
