About the AirTAC GC300-08 FRL Unit (GC30008LNW)
GC30008LNW is an AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one 300-size set with PT1/4 ports. The filter stage removes water and particulate down to 5 um (the W fine-grade element), the regulator is the low-pressure type variant and, with the differential-pressure drain fitted here, adjusts 0.15-0.9 MPa (20-130 psi), and the lubricator meters oil mist into the air line. This code carries no pressure gauge (N) and the standard PT thread.
This is a genuine AirTAC part. The GC series is offered in 200, 300, 400 and 600 sizes, with PT as the standard thread and G (BSPP) or NPT as catalogue options, a choice of differential-pressure, automatic or manual drain, and 40 um standard or 5 um filter elements. Flow is published as curves rather than a single rating, so we confirm sizing and 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.
Model Code: AirTAC GC300-08 FRL Unit (GC30008LNW)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 GC300-08 FRL Unit (GC30008LNW) Is Used
CNC machining centers
Feeding the clamp fixtures, tool-change cylinders and air-blast nozzles on a CNC machining center, where the 5 um element helps keep fine debris out of pilot valves and actuators.
Carton sealing lines
Supplying filtered, regulated, lubricated air to case erectors and carton sealers on a packaging conveyor, with the regulator holding a steady setting for repeatable cylinder strokes.
Pneumatic assembly benches
Point-of-use treatment at assembly stations running impact wrenches and nutrunners, where the lubricator meters oil mist into the tool air supply through a 1/4 in drop.
Is the AirTAC GC300-08 FRL Unit (GC30008LNW) the Right Station?
Size 300 with 1/4 in PT ports is a mid-range step in the G-series; drop to size 200 for compact branches or step up to 400/600 for larger mains. Drain choice matters: this unit uses the differential-pressure drain; order M for manual bleeding on a maintenance round or A for automatic draining. The 5 um W element is the right pick when finer particulate control is wanted; the standard 40 um element is available. If you need a pressure readout, choose a code with the gauge position set (C round or F square, scale 1 MPa, 2 psi or 3 bar). PT thread is standard; specify G (BSPP) or NPT to match existing piping, and max inlet pressure is 1.0 MPa (145 psi) with -5 to 70 C operation. Flow is published as curves, not a single rating - ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008LNW) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no single flow number is quoted here. Send us your line pressure and air demand and we will confirm sizing against the datasheet on request.
The N in GC30008LNW means the set is built without a gauge. If you want a readout, select a GC code with the gauge position left blank (gauge included) or with C for a round gauge or F for a square gauge, in MPa (1), psi (2) or bar (3) scale.
