AirTAC GC300-15 FRL Unit (GC30015LNW)
The AirTAC AirTAC GC300-15 FRL Unit (GC30015LNW) 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 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-15 FRL Unit (GC30015LNW)
GC30015LNW combines two decode choices in one AirTAC G-series set: the W suffix specifies the fine 5 um filter element, and the N suffix deletes the regulator gauge. You still receive all three functions - filter, low-pressure type regulator (the L suffix) and lubricator - as separate bodies in one F.R.L. combination. The filter bowl drains by differential pressure, and the 300 size carries 1/2 inch ports in PT thread as standard.
This is a genuine AirTAC part distributed for the US market. Within the G-series you can select the 200/300/400/600 sizes from 1/8 to 1 inch ports, G (BSPP) or NPT thread, 40 um or 5 um filtration, automatic or manual drain in place of the differential-pressure bowl, and gauge versions in MPa, psi or bar scales if local indication is wanted. Rated flow is published as curves rather than a single 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 (GC30015LNW)
| 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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 (GC30015LNW) Is Used
Instrument air for test rigs
Fine-filtered, regulated and lubricated air for pneumatic functions on a test bench, where pressure is monitored on the rig's own transducer so the F.R.L. is ordered without a gauge.
Clean air to assembly actuators
Supplies conditioned air to small-bore cylinders and air fingers on an electronics or small-parts assembly station, with the 5 um element protecting the fine control valves downstream.
Process valve actuation panel
Prepares the pilot and actuation air for automated process valves on a skid, keeping condensate and fine particulate out of the positioners while the panel's own indicator shows the set pressure.
Is the AirTAC GC300-15 FRL Unit (GC30015LNW) the Right Station?
Pick this configuration when you need fine 5 um filtration, no local gauge, and 1/2 inch PT ports in the 300 size; if you later want pressure indication, the gauge-fitted and round-gauge versions are catalogue alternatives. The other port steps (200/400/600) cover 1/8 to 1 inch circuits, and we confirm flow against the published curves before ordering. Drain is differential-pressure as standard, with automatic (A) and manual (M) options available. The L suffix marks the low-pressure regulator type, so confirm its set-point range from the datasheet with us. PT is the standard thread; G (BSPP) and NPT are orderable thread options.
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 (GC30015LNW) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated number, so we do not state a figure here. Give us your line pressure, downstream demand and acceptable pressure drop and we will confirm the sizing from the datasheet on request.
GC is the three-piece F.R.L. set (filter, regulator, lubricator), 300 is the size with PT1/2 ports, L is the low-pressure regulator type, N means no gauge is fitted, W specifies the 5 um filter grade, and the drain is the differential-pressure type as standard.
