About the AirTAC GC300-15 FRL Unit (GC30015C1)
GC30015C1 is a three-piece AirTAC G-series F.R.L. combination: separate filter, regulator and lubricator, size 300, PT1/2 ports. The filter runs the standard 40 um element for general-purpose water and particulate removal, the regulator holds downstream pressure in the 0.15-0.9 MPa (20-130 psi) range, and the lubricator supplies oil mist to downstream equipment. Bowls are polycarbonate on this size with the default differential-pressure drain, and this configuration carries the round external gauge with MPa scale so operators can read the regulated pressure directly.
This is a genuine AirTAC part. The G-series offers sizes 200 to 600, ports from 1/8 in. to 1 in., 40 um standard or 5 um elements, automatic, manual or differential-pressure drains, embedded square or external round gauges in MPa, psi or bar, and the optional reverse/check valve. Medium is compressed air only, max working pressure 1.0 MPa (145 psi), operating temperature -5 to 70 C, non-freezing. Flow is published as curves, not a single rated figure; we confirm datasheet values 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: GF300-15 filter, GR300-15 regulator and GL300-15 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 GC300-15 FRL Unit (GC30015C1) Is Used
Laboratory test-rig air supply
Conditioning air to a test bench where technicians read and log the regulated pressure from the round MPa gauge before each run, with the 40 um element handling general supply air.
Process valve-actuation panel
Supplying quarter-turn pneumatic actuators on a process skid, with the gauge giving operators a visible setpoint and the lubricator conditioning the actuator air.
Printing-press roller and clamp air
Feeding the roller-loading and web-clamp cylinders on a printing press, where operators monitor the regulated line pressure at a glance on the external gauge.
Is the AirTAC GC300-15 FRL Unit (GC30015C1) the Right Station?
Size 300 with PT1/2 ports is the natural match for 1/2 in. mains feeding whole machines or work cells; match the size step to your demand and let us check the published flow curve first. This code takes the default differential-pressure drain, which passes condensate as the pressure differential builds - switch to automatic for unattended operation or manual (0.05-0.9 MPa regulating range) for daily-check points. The 40 um element is the standard grade; specify the W variant if you need 5 um for valves or instruments. The C1 suffix gives a round external gauge on MPa scale; psi or bar scales and the embedded square gauge are alternatives. PT is the standard thread, G (BSPP) and NPT are order options; brackets included.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC GC300-15 FRL Unit (GC30015C1) FAQ
AirTAC publishes flow for the GC300 series as curves rather than a single rated figure, so there is no one number to quote. Tell us your line pressure, downstream consumption and allowable pressure drop and we will confirm the fit from the datasheet on request before ordering.
C1 means this configuration carries the external round gauge with MPa scale. The drain is the default differential-pressure type, not automatic: condensate is discharged as the differential across the element builds. For unattended draining, choose the A variant, for example GC30015ANW.
