About the Airtac GC FRL Unit GC300C15AC1K
GC300C15AC1K is a genuine AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator for compressed air. This 300-size set has 1/2 in PT ports, an automatic drain on the filter bowl, the standard 40 um filter element, a round pressure gauge reading in MPa, and a reverse/check valve fitted. The 300-size bowls are polycarbonate, and with the automatic drain the regulator adjusts across 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part rated for a maximum working pressure of 1.0 MPa (145 psi) at -5 to 70 C, non-freezing. The GC family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, PT, G(BSPP) or NPT threads, 40 um or 5 um filtration, manual, automatic or differential-pressure drains, and round or square gauges in MPa, psi or bar. Flow is published as curves rather than a single rating, so we confirm figures from the datasheet 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 GC300C15AC1K Is Used
CNC machining center clamp circuit
Filtered, regulated and lubricated air for the tool-clamp and chip-conveyor cylinders on a machining center; the fitted check valve holds downstream pressure if the shop supply dips mid-cycle.
Carton sealing line
Supplies the case-sealer cylinders and directional valves on a packaging conveyor. The automatic drain clears condensate during multi-shift runs without an operator at the set.
Pneumatic process valve skid
Conditions the actuation air for quarter-turn valves on a water-treatment skid, with the MPa gauge giving operators a local line-pressure check at the manifold.
Is the Airtac GC FRL Unit GC300C15AC1K the Right Station?
The 300 frame with 1/2 in PT ports is the mid-size step in the GC range; step up to 400 or 600 for larger ports, or down to 200 for compact lines. This code carries the automatic drain, which suits unattended multi-shift running; manual and differential-pressure drains are the alternatives. Filtration is the standard 40 um element, with 5 um (W) available for finer protection. The gauge here is the round external type on an MPa scale; square gauges and psi or bar scales are other options, and G or NPT threads replace PT to order. Because flow is published as curves, not a single rated figure, 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 GC300C15AC1K FAQ
AirTAC publishes flow for the GC series as characteristic curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the sizing from the datasheet on request.
A is an automatic drain, M is manual, and a blank position is the differential-pressure drain. This model carries A, so the filter bowl discharges condensate automatically; with a manual drain the regulation range widens to 0.05-0.9 MPa, versus 0.15-0.9 MPa here.
