About the AirTAC GC300-15 FRL Unit (GC30015ALC1)
The AirTAC GC series is a three-unit F.R.L. set of separate filter, regulator and lubricator units, so one air drop can be cleaned, regulated and lubricated at a single point. This GC30015ALC1 is the size 300 unit with a PT1/2 port, the standard 40 um element, an automatic drain (A) and the L low-pressure regulator type, whose adjustment tops out at 0.4 MPa instead of the standard ceiling; a round external gauge reading in MPa (C1) is included. The filter and lubricator bowls are polycarbonate at this size, and the working range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part with a maximum inlet pressure of 1.0 MPa (145 psi). Across the GC family you can choose sizes 200 to 600, 40 um or 5 um elements, differential, automatic or manual drains, standard or low-pressure regulators, gauge variants and PT, G (BSPP) or NPT threads. Flow is published as curves, so we confirm sizing and the datasheet 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 (GC30015ALC1)
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 (GC30015ALC1) Is Used
Agitated coating and mixing tanks
Regulating low-pressure air sparged into agitated mixing and coating tanks, where the L-type regulator holds a gentle, repeatable setpoint well below standard plant pressure.
Air-rinse section of a bottling line
Supplying the blow-out nozzles that purge containers before filling, where the low-pressure regulator limits nozzle force and the automatic drain handles condensate from a long air run.
Air-nozzle blow-off on food conveyors
Feeding air-nozzle blow-off stations that clear crumbs and dust from product and belt surfaces on a packaging conveyor, with the 40 um element suiting general-duty nozzles.
Is the AirTAC GC300-15 FRL Unit (GC30015ALC1) the Right Station?
Choose this code when the circuit must run at reduced pressure: the L type lets the regulator be set anywhere up to 0.4 MPa, below the standard unit's window, which suits circuits fed from a full-pressure main but working at low setpoints. The 40 um element is the standard grade, adequate for general plant air; select the W 5 um variant where downstream equipment needs finer filtration. The A automatic drain suits unattended operation; M manual and the differential-pressure default are the alternatives. The C1 gauge reads in MPa, with psi and bar scales available. Thread is PT; G (BSPP) and NPT versions are catalogue options. Flow is published as curves, not a single rating, so ask us to confirm this size against your application's flow 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 (GC30015ALC1) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not state one number here. Tell us your inlet pressure, setpoint and the equipment being fed, and we will confirm the sizing and flow curve from the datasheet on request.
L selects the low-pressure regulator type: its adjustment range tops out at 0.4 MPa rather than the standard ceiling, for circuits designed to run at reduced pressure. Filter, lubricator, automatic drain, PT1/2 port and the round MPa gauge are otherwise the same specification as the standard size 300 combination.
