About the Airtac GC FRL Unit GC300C15AC1
GC300C15AC1 is a genuine AirTAC G-series three-unit F.R.L. combination: separate air filter, pressure regulator and oil-mist lubricator conditioning compressed air as one set. This configuration is size 300 with PT1/2 in ports, automatic drain, standard 40 um filtration, an external round gauge on MPa scale, standard regulator type and no reverse valve. In use the filter removes water and particulate, condensate is discharged from the bowl automatically rather than on a manual round, the regulator holds a set downstream pressure (0.15-0.9 MPa / 20-130 psi on this drain type) readable on the MPa gauge, and the lubricator meters oil mist downstream. Maximum working pressure is 1.0 MPa (145 psi), media is compressed air only, operating range -5 to 70 C (non-freezing). At size 300 the filter and lubricator bowls are PC (polycarbonate); the regulator has no bowl.
The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, with drain, filtration grade, gauge and thread options selectable across the family. Published figures cover function, ports, pressures and temperature; flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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.

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 GC300C15AC1 Is Used
Robot welding cell
Conditioning the 1/2 in supply feeding grippers, weld-gun clamps and purge-air lines on a spot-welding robot; the round MPa gauge lets the setter verify pressure at the cell.
Bottling line actuators
Supplying filler-head lift cylinders, capper heads and reject pushers on a bottling line; the automatic drain clears bowl condensate without stopping for operator rounds.
Machine pneumatic control panel
Feeding a bank of directional valves and actuators on a machine control panel; the gauge shows the regulated setting and the auto drain keeps the filter bowl clear on a continuous line.
Is the Airtac GC FRL Unit GC300C15AC1 the Right Station?
Match the size step (200 to 600) to your port and demand; this 300 unit gives PT1/2 in. Drain choice matters on duty cycles: automatic (A, as here) clears condensate without operator rounds, while differential-pressure (default) and manual (M) suit other regimes. Filtration is 40 um standard or 5 um with W. Gauge options are none (N), or round or square with MPa, psi or bar scale - this unit carries a round MPa gauge. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not a single rating, 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-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C15AC1 FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number. Send us your working pressure and required demand and we will confirm the flow and datasheet figures for this PT1/2 in unit on request.
A is the automatic drain, which discharges bowl condensate on its own instead of the differential-pressure default or a manual drain; C is the external round gauge and 1 is its MPa scale. The base code decodes as size 300, PT1/2 in ports, 40 um standard filtration, PT thread.
