About the Airtac GC FRL Unit GC300C15N
GC300C15N is an AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set. At size 300 with a 1/2 in. PT port, it removes water and particulate down to 40 um, holds downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) range of its differential-pressure-drain regulator, and meters oil mist to the air stream. The N code means no gauge is fitted, and the polycarbonate bowls suit the -5 to 70 C working range.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with optional 5 um filtering (W), automatic or manual drains, round or square gauges in MPa, psi or bar scales, G (BSPP) or NPT threads and a reverse/check valve (K). Maximum inlet pressure is 1.0 MPa (145 psi). AirTAC publishes flow for this series as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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 GC300C15N Is Used
CNC machining centre
Supplies filtered, regulated and lubricated air to the tool-clamp and pallet-locking cylinders on a CNC machining centre, with the 40 um element catching pipe scale and condensed water before it reaches the drawbar circuit.
Carton sealing line
Feeds the fold and press cylinders on a carton-forming and sealing conveyor, holding a steady regulated setpoint through the shift while the lubricator conditions the cylinder seals.
Pick-and-place gantry
Services the gripper cylinders on a pick-and-place gantry loader, where 40 um filtration and stable regulated pressure keep the valve spools and seals working reliably cycle after cycle.
Is the Airtac GC FRL Unit GC300C15N the Right Station?
Size 300 with a 1/2 in. port is the mid step of the GC range: step to 400 or 600 for larger ports and more flow, or to 200 for compact panels. This unit uses the differential-pressure drain default; automatic (A) or manual (M) drains can be ordered instead. Filter grade is 40 um standard, 5 um with the W code. The N code omits the gauge - specify a round or square gauge with MPa, psi or bar scale if you want a local pressure reading. PT is the standard thread; G (BSPP) and NPT are catalogue thread options. AirTAC publishes flow as curves, not a single rating, so send us your flow and pressure requirements and we will confirm the right size before you order.
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 GC300C15N FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm the sizing against the datasheet curves before you order.
N means no gauge is supplied with the regulator section, so downstream pressure is read from your machine's own instrumentation. If you want a local reading, the same set can be ordered with a round or square gauge in MPa, psi or bar scale.
