About the Airtac GC FRL Unit GC300C08AF1
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one air-preparation set. This GC300C08AF1 is the 300 size with PT1/4 (1/4 in.) ports. The filter carries the standard 40 um element for general plant air, the bowl drains automatically (A suffix) so condensate is ejected without manual attention, and an embedded square pressure gauge with an MPa scale (F1) shows the regulated pressure. The filter and lubricator bowls on the 300 size are polycarbonate.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600 with a choice of drain types, 40 um standard or 5 um filter elements, round or square gauges in MPa, psi or bar scales, and PT, G(BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and the operating range is -5 to 70 C, non-freezing. Flow is published as curves rather than one rated figure, so ask us and we will confirm the datasheet figures 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 GC300C08AF1 Is Used
Assembly bench air tools
Filters, regulates and lubricates the air feeding impact drivers, nutrunners and ratchets on an assembly bench, with the 40 um element suiting standard shop air.
Indexing table on a packaging line
Supplies the rotary indexing table and its pick-and-place cylinders on a packaging line, where the automatic drain handles condensate during long production runs.
Air cylinder circuit on a material-handling lift
Prepares air for the lift and clamp cylinders of a handling or palletizing station, keeping the pressure gauge visible at the machine for quick setting checks.
Is the Airtac GC FRL Unit GC300C08AF1 the Right Station?
Size 300 is the mid step of the G series: step up to GC400 or GC600 (larger ports, up to 1 in.) for higher demand, or down to GC200 (1/8 in. and 1/4 in. ports) for compact circuits. The automatic drain here gives a regulator adjust range of 0.15-0.9 MPa (20-130 psi); manual-drain and differential-pressure-drain versions are also orderable, with manual drain widening the range to 0.05-0.9 MPa. This model uses the standard 40 um element; add the W suffix for the 5 um grade where finer filtration is required. The F1 gauge is the embedded square type in MPa; round gauges and psi or bar scales are specification options, as are PT, G(BSPP) and NPT threads. Flow is published as curves, not a single rating, so ask us to 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 GC300C08AF1 FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet curve and verify the 300-size set against your flow demand on request before you order.
F1 fits the embedded square gauge, as on this model; C1 fits the external round gauge. Both are supplied here with an MPa scale, and psi or bar scales are orderable alternatives. The gauge reads regulated downstream pressure on the regulator section.
