About the AirTAC GC300-10 FRL Unit (GC30010C3K)
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator piped as one set, so compressed air is cleaned, regulated and oil-mist lubricated before it reaches your valves, cylinders and air tools. This GC30010C3K is the size 300 frame with PT3/8 ports, the standard 40 um filter element and a differential-pressure drain on the filter bowl. The regulator carries the C3 gauge option, an external round gauge with a bar scale, and the K option adds a reverse check valve so air cannot flow back through the set. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusting range with the differential-pressure drain is 0.15-0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied by an authorised distributor. The GC series spans sizes 200, 300, 400 and 600 with matching port sizes, and the same frame can be ordered with a 5 um element (W), automatic or manual drain, a square embedded gauge in MPa, psi or bar scales, or G (BSPP) and NPT threads instead of PT. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details for your application 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 (GC30010C3K) Is Used
CNC machining centre air drop
Feeds filtered, regulated and lubricated air to the tool-clamp cylinders, chip-door actuators and directional valves on a machining centre's shop-air drop, with the check valve blocking backflow in the branch.
Packaging line case sealers
Supplies the carton-sealing and case-packing cylinders on a packaging conveyor, keeping the air dry and oil-misted so flap-tuck and press cylinders cycle smoothly through long shifts.
Automotive assembly air tools
Conditions the air feeding impact wrenches, nutrunners and air ratchets at an assembly station, where the lubricator's oil mist protects tool motors and the regulator holds a steady working pressure.
Is the AirTAC GC300-10 FRL Unit (GC30010C3K) the Right Station?
Size 300 with 3/8 in. ports sits in the middle of the GC range; step up to 400/600 or down to 200/100-class ports as your line flow demands. The 40 um element is the standard grade; choose the W suffix for 5 um when downstream valves need finer filtration. The differential-pressure drain used here is the default; automatic (A) and manual (M) drain variants are also orderable. This code specifies the C3 external round gauge with a bar scale; square embedded gauges in MPa, psi or bar scales are alternatives. PT thread is the standard for this code, with G (BSPP) and NPT available as catalogue options, and the K suffix fits a reverse check valve. Flow is published as curves, not a single rating, so 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 (GC30010C3K) FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated number, so we do not quote one figure here. Tell us your line pressure and air demand and we will confirm the correct size from the datasheet curves on request.
C3 specifies an external round pressure gauge with a bar scale on the regulator, and K means a reverse check valve is fitted in the set. The filter uses the standard 40 um element with a differential-pressure drain; 5 um (W) and automatic or manual drain versions are separate orderable codes.
