About the AirTAC GC300-10 FRL Unit (GC30010F1K)
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set, cleaning, regulating and oil-mist lubricating compressed air before it reaches your actuators and valves. This GC30010F1K is the size 300 frame with PT3/8 ports, the standard 40 um filter element and a differential-pressure drain, with the regulator's embedded square gauge on an MPa scale (the F1 option). The K option adds a reverse check valve so air cannot flow back through the set toward the supply side. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusting range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the working temperature is -5 to 70 C, non-freezing. The size 300 bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC series spans sizes 200 to 600 with matching ports, and the same set is available with a 5 um element (W), automatic or manual drain, an external round gauge or psi and bar scales, and G (BSPP) or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures and sizing on request before ordering.

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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010F1K) Is Used
Stamping press counterbalance circuits
Conditions the air feeding counterbalance and part-ejection cylinders on a stamping press, with the check valve preventing backflow through the set and the regulator holding the balance pressure.
Warehouse sortation diverters
Supplies the diverter and pusher cylinders along a sortation conveyor, delivering filtered, regulated, lubricated air for thousands of divert cycles, with the reverse valve isolating the branch.
Bolt-making machine air circuits
Feeds the wire-feed clamps and cut-off slides on a cold-forming fastener machine, where steady regulated pressure and oil mist keep the high-cycle cylinders moving reliably.
Is the AirTAC GC300-10 FRL Unit (GC30010F1K) the Right Station?
Choose this code when you want the standard size 300 F.R.L. with the F1 embedded square MPa gauge plus the K reverse check valve in one order; the equivalent set without the valve is GC30010F1. The 40 um element and differential-pressure drain are the defaults, with 5 um (W) and automatic or manual drain codes as alternatives. Size 300 with 3/8 in. ports is the mid-range frame; move up or down the 200-600 range as your branch flow demands, and order G (BSPP) or NPT threads if your piping is not PT. Because GC 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 (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010F1K) FAQ
AirTAC publishes GC-series flow as performance curves rather than one rated figure, so we do not quote a number here. Give us your working pressure and air consumption and we will confirm from the datasheet that size 300 with 3/8 in. ports suits your application.
K means a reverse check valve is fitted, so air cannot flow backwards through the set toward the supply side. Otherwise this is the size 300 standard build: PT3/8 ports, 40 um element, differential-pressure drain and the embedded square gauge reading in MPa.
