AirTAC GC300-15 FRL Unit (GC30015LN)
The AirTAC AirTAC GC300-15 FRL Unit (GC30015LN) 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 (GC30015LN)
GC30015LN is a three-piece AirTAC G-series F.R.L. combination supplied without a gauge: the N in the code deletes the regulator gauge. You still get the full three functions - a separate filter with the standard 40 um element and a differential-pressure drain bowl, a low-pressure type regulator (the L suffix), and a lubricator for oil-mist service. The 300 size is fitted with 1/2 inch ports in PT thread as standard.
This is a genuine AirTAC part supplied for the US market. The G-series offers the 200/300/400/600 sizes from 1/8 to 1 inch ports, G (BSPP) and NPT thread options, the 5 um (W) filter grade, automatic or manual drain choices, and versions with an embedded square or external round gauge in MPa, psi or bar scales. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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.
Model Code: AirTAC GC300-15 FRL Unit (GC30015LN)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |

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 (GC30015LN) Is Used
Maintenance shop air drop
A wall-mounted F.R.L. at a maintenance drop: filtered, pressure-set and lubricated air for impact tools, air ratchets and blow-off work, with pressure read on the shop's existing gauge.
Woodworking machine feed
Conditions the air feeding hold-downs and dust-gate cylinders on a saw or router line, where the panel already carries its own pressure indication so the unit is ordered without a gauge.
Truck and trailer service bay
Point-of-use preparation of shop air for brake-cage work and air-tool service on commercial vehicles, with the regulator set locally and monitored on the bay's master gauge.
Is the AirTAC GC300-15 FRL Unit (GC30015LN) the Right Station?
The LN configuration suits panels where pressure is read on a separate instrument or where no local indication is wanted; if you later need a gauge, the F1 square MPa version (GC30015LF1) is the same set with the gauge fitted. The 300 size gives you 1/2 inch PT ports; the 200/400/600 sizes cover other port steps and we confirm flow against the published curves before you order. Drain is differential-pressure as standard, with automatic (A) and manual (M) options; filtration is the standard 40 um element, with 5 um available as the W suffix. The L suffix marks the low-pressure regulator type - confirm its set-point range from the datasheet with us. G (BSPP) and NPT threads are catalogue options to the standard PT.
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 (GC30015LN) FAQ
AirTAC publishes G-series flow as performance curves rather than one rated number, so we do not quote a figure on the page. Share your line pressure and downstream air demand and we will confirm the correct size from the datasheet on request.
The N in the code deletes the regulator gauge. If you want local pressure indication, GC30015LF1 is the same three-unit set with an embedded square MPa gauge; external round gauges and psi or bar scales are also catalogue options.
