AirTAC GC300-15 FRL Unit (GC30015LC1)
The AirTAC AirTAC GC300-15 FRL Unit (GC30015LC1) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-15 FRL Unit (GC30015LC1)
The AirTAC GC series is a three-unit F.R.L. set - separate filter, regulator and lubricator - that conditions compressed air in one assembly. This GC30015LC1 is the low-pressure type (L), the 300 size with 1/2 inch PT ports, the standard 40 um filter element, a differential-pressure bowl drain and an external round gauge scaled in MPa.
This is a genuine AirTAC part. The G series spans 200/300/400/600 sizes with a choice of drains, filter grades, gauge styles and G or NPT threads; max working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C (non-freezing). The bowl on this 300 size is polycarbonate (PC). Because this is the low-pressure type, we confirm the exact adjustment envelope and all datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GC30015LC1) Is Used
Laboratory air service lines
Conditions low-pressure compressed air feeding bench valves and glassware-drying stations in a lab service ring, read on the MPa gauge.
Thermoforming line air circuits
Regulates supply to low-pressure forming and ejection air circuits on a plastics thermoforming line, where full plant pressure is not wanted.
Air table and flotation circuits
Feeds air tables and flotation pads that run at reduced pressure, with filtered, oil-misted air protecting the porous surfaces.
Is the AirTAC GC300-15 FRL Unit (GC30015LC1) the Right Station?
Match the 200/300/400/600 size to your piping and demand - the 300 size here uses 1/2 inch PT ports as standard, with G (BSPP) and NPT available as catalogue options. The L code selects the low-pressure regulator type; confirm the working pressure of your circuit with us before ordering. Choose the standard type if your line runs at full plant pressure.
The round MPa gauge sits external to the body, and the 40 um element is the standard filtration grade (5 um is available as W). 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 (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 (GC30015LC1) FAQ
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote one number here. Share your application and we will confirm the datasheet flow data and the right size for your circuit on request.
The L code selects the low-pressure regulator type for circuits that run below standard plant pressure, and C1 specifies an external round gauge scaled in MPa. We confirm the exact adjustment range of the low-pressure type on request before you order.
