About the Airtac GC FRL Unit GC300C08AF3G
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator, so your downstream equipment gets filtered, regulated, oil-misted compressed air. This GC300C08AF3G is the 300 size with G1/4 (BSPP) ports, an automatic filter drain, a 5 um (W) element and a square pressure gauge scaled in bar. The standard regulator adjusts 0.15-0.9 MPa (20-130 psi) with automatic drain, and maximum working pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from airtacdistr.com. The G series runs in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch; filter grade, drain type, gauge scale and thread are selectable, and the G (BSPP) thread on this unit is a catalogue option ordered instead of the PT standard. The PC bowls on the filter and lubricator suit -5 to 70 C, non-freezing. AirTAC publishes flow as curves rather than a single rating, so we confirm flow and 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 GC300C08AF3G Is Used
Laboratory instrumentation air
Conditions the supply to analytical instruments and pneumatic sample-handling actuators in a lab, where the 5 um element, stable regulated pressure and bar-scale gauge match lab standards and fittings.
European-built CNC periphery
Feeds the pneumatic chip-blow-off, clamping and curtain circuits around a European-built machining centre wired for G (BSPP) ports, keeping the machine's air supply filtered, regulated and lubricated.
Process valve actuation skids
Supplies quarter-turn pneumatic actuators and positioner air on a process skid, with clean 5 um air for the positioner and regulated pressure matching the actuator's setting.
Is the Airtac GC FRL Unit GC300C08AF3G the Right Station?
The 300 body with G1/4 ports suits European-plumbed 1/4-inch circuits where BSPP fittings are standard; NPT and PT versions of the same set are also in the range, and ports run 1/8 to 1 inch across the series. The bar-scale square gauge reads in the units your maintenance team uses; MPa and psi scales are alternatives. The automatic drain keeps condensate off your floor without daily checks, and the 5 um (W) element is the right pick for paint, instrumentation or clean-air points - the standard 40 um element covers general plant air. Flow is published as curves, not a single rating - 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 GC300C08AF3G FAQ
AirTAC does not publish a single rated flow figure for the GC series - flow is given as performance curves. Tell us your operating pressure and air demand and we will confirm the correct size and the datasheet figures for your application on request.
The trailing G decodes to G (BSPP) ports instead of the PT standard, and F3 decodes to a square gauge scaled in bar - a combination commonly requested for European-plumbed equipment. psi and MPa gauge scales and NPT or PT threads are alternative order options.
