About the Airtac GC FRL Unit GC300C15MN
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, plumbed in line so one order covers filtration, regulation and lubrication. This GC300C15MN is the size 300 set with 1/2in PT ports. The filter bowl has a manual drain and a 40 um standard element, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) in this manual-drain configuration, and the lubricator mists oil downstream to keep air tools and cylinders running. No gauge is fitted on this variant (N). Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, thread (PT standard, G and NPT as options), drain type (differential-pressure, automatic or manual) and 40 um or 5 um filtration. Published flow figures are curves rather than a single rating, so ask us to confirm sizing or send 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 GC300C15MN Is Used
CNC machining center air supply
Feeding filtered, regulated and lubricated air to the tool-change cylinders and clamping fixtures on a CNC machining center, with a 40 um element protecting the valves and oil mist keeping the actuators sealed and smooth.
Packaging line stopper and pusher cylinders
Conditioning the air feeding the reject pushers and stopper cylinders on a carton packaging line: clean, regulated pressure for consistent stroke timing, plus lubrication for long cylinder life.
Assembly hall air drops
Mounted at the wall drop point of an assembly hall to supply bench air tools and pneumatic screwdrivers with clean, regulated, lubricated air through the 1/2in main.
Is the Airtac GC FRL Unit GC300C15MN the Right Station?
Size 300 with 1/2in PT ports is the mid-range step in the GC line: step up to 400 or 600 or down to 200 depending on the flow your line needs and the port size of your air preparation drop. Manual drain means someone opens the filter bowl drain valve during checks - choose automatic or differential-pressure drain if the installation is unattended. The 40 um element is standard for general plant air; pick the 5 um (W) variant for finer protection. This variant has no gauge (N) and no check valve. PT is the standard thread; G (BSPP) and NPT are catalogue options you can order. Flow for the GC series is published as curves, not a single rated figure, so please 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-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C15MN FAQ
AirTAC publishes flow for the GC series as performance curves, not as a single rated figure, so we do not quote one number. Tell us your application and we will confirm the sizing and send the datasheet flow curve on request.
Manual drain means the filter bowl drain valve is opened by hand during maintenance to let collected water out. The GC series is also available with automatic drain (A) or differential-pressure drain (the default, blank) if you prefer not to rely on manual draining.
