AirTAC GC300-10 FRL Unit (GC30010AC1K)
The AirTAC AirTAC GC300-10 FRL Unit (GC30010AC1K) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/8" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-10 FRL Unit (GC30010AC1K)
The GC30010AC1K is an AirTAC GC-series three-unit F.R.L. combination - separate filter, regulator and lubricator - with the K option adding a reverse (check) valve to the set. It is a size 300 unit ported PT3/8 (PT as standard) for compressed air. The filter bowl carries an automatic drain, the standard 40 um element suits general plant air, and the regulator covers 0.15-0.9 MPa (20-130 psi) in this automatic-drain configuration. The C1 code brings an external round gauge with an MPa scale.
This is a genuine AirTAC part from the G series, offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch. Alternative drains, filter grades, gauges and G/BSPP or NPT threads are catalogue options. Flow is published as curves rather than a single rated figure, so we confirm sizing and datasheet figures 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.
Model Code: AirTAC GC300-10 FRL Unit (GC30010AC1K)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|

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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010AC1K) Is Used
Pneumatic press drop line
Regulated, filtered and lubricated air to a pneumatic press station, with the reverse (check) valve helping hold downstream pressure should the upstream supply drop.
Bottle-filling line actuators
Air preparation for filler and capper actuation on a bottling conveyor, where the automatic drain deals with condensate from high daily air throughput.
Robotics workstation supply
A point-of-use F.R.L. set feeding grippers and end-of-arm tooling on a robot cell, giving stable settable pressure read on the MPa gauge.
Is the AirTAC GC300-10 FRL Unit (GC30010AC1K) the Right Station?
Choose the K version when the downstream circuit needs a reverse (check) valve built into the set, for example to hold downstream pressure if upstream supply is interrupted. Size 300 with the 3/8 inch PT port covers mid-range air demand; move to size 400/600 for higher flow or size 200 for smaller lines. The automatic drain (A) minimises maintenance; manual and differential-pressure drains also exist in the series. The standard 40 um grade fits general air, and the W option provides 5 um filtration.
This code includes a round MPa-scale gauge; square gauges and psi or bar scales can be ordered instead. Thread is PT as standard with G (BSPP) and NPT as options. As flow is published only as curves, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010AC1K) FAQ
AirTAC publishes flow as performance curves rather than a single rated figure, so we do not quote one number here. Share your working pressure and consumption and we will confirm the sizing from the datasheet on request.
K specifies that a reverse (check) valve is fitted to this three-unit set. The rest of the code decodes as size 300, PT3/8 port, PT thread, automatic drain, standard 40 um filtration and an external round MPa-scale gauge.
