About the AirTAC GC300-15 FRL Unit (GC30015ALNW)
GC30015ALNW is a genuine AirTAC GC three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator, each installed as its own module in the line. This 300-size set is supplied with a PT1/2 port, an automatic drain on the filter bowl, the finer 5 um (W) filter element and no pressure gauge (N). The L suffix marks the low-pressure type, intended for circuits that run below standard line pressure. All bowls are polycarbonate at this size, the medium is compressed air, and the set works from -5 to 70 C (non-freezing). Max working pressure is 1.0 MPa (145 psi).
AirTAC builds the GC series in 200, 300, 400 and 600 sizes with 1/8 in through 1 in ports, a choice of G (BSPP) or NPT threads as catalogue options, automatic, manual or differential-pressure drains, 5 um (W) or 40 um filtration, and gauge variants. Flow for the GC series is published as curves rather than a single rating, so we confirm the datasheet and sizing 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.
Model Code: AirTAC GC300-15 FRL Unit (GC30015ALNW)
| 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". |
| A | Drain: Automatic 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 (GC30015ALNW) Is Used
Pilot-air feed on a cartoning machine
Supplying 5 um filtered, regulated and lubricated air to pilot valves on a cartoning machine, keeping fine particulate out of the control circuit.
Thermoformer valve train
Conditioning air for sealing and cut-off cylinders on a thermoforming packaging line, where the 5 um element protects the downstream valve train.
Process-skid control panel
Feeding lubricated, low-pressure regulated air to small actuators and solenoid blocks on a process-skid control panel with finer-than-standard filtration.
Is the AirTAC GC300-15 FRL Unit (GC30015ALNW) the Right Station?
The 5 um (W) element is the key choice here: it filters more finely than the 40 um standard element, which suits control valves and pilot circuits that dislike fine particulate. The 300-size 1/2 in port sets the flow path; step up to 400 or 600 if your demand needs a larger port. The automatic drain handles condensate without attention, and manual or differential-pressure drain variants exist in the series. Thread is PT as standard - order G (BSPP) or NPT if your piping differs.
Flow through the GC series is published as curves, not a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and port size and we will confirm the datasheet figures and check the sizing against your application before you order.
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 (GC30015ALNW) FAQ
AirTAC publishes GC-series flow as curves, not a single rated figure, so we do not quote a number on this page. Send us your line pressure, downstream demand and port size, and we will confirm the datasheet figures and check the sizing against your application before you order.
The standard GC filter element is 40 um; the W suffix in this code selects the 5 um element, which removes finer particulate. Choose W for pilot valves, control circuits and other sensitive downstream equipment, and standard 40 um for general plant air.
