About the AirTAC GC300-08 FRL Unit (GC30008MLNW)
GC30008MLNW is an AirTAC GC three-unit air-treatment combination: a separate air filter, pressure regulator and lubricator piped together. This 300-size set is ported 1/4 in with standard PT thread. The filter bowl has a manual drain and the finer 5 um element (code W); the regulator is the low-pressure type (code L) with a 0.05-0.9 MPa (7-130 psi) setting range for this manual-drain configuration; code N means the set is supplied without a gauge. Maximum working pressure is 1.0 MPa (145 psi), temperature range is -5 to 70 C (non-freezing), and the 300-size filter and lubricator bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and drain, filter grade, gauge, thread and valve options are order choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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 (GC30008MLNW)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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 (GC30008MLNW) Is Used
Laboratory test rig
Clean supply air for a materials test bench: the 5 um element keeps fine contamination away from transducers and precision valves, the low-pressure type regulator allows gentle setting of test pressures, and the manual drain suits supervised lab use.
Control cabinet feed
Air preparation inside a machine control cabinet feeding small pneumatic pilot valves: the finer element protects the compact internal orifices, and the lubricator feeds only where valve makers specify oiled air.
Packaging carton sealer
Supply to the tape heads and flap cylinders of a carton sealing machine: regulated low-pressure air with 5 um filtration for the sealer's small valve passages, and a manual drain bled during line changeovers.
Is the AirTAC GC300-08 FRL Unit (GC30008MLNW) the Right Station?
Pick the 300 size with 1/4 in PT ports for compact supply lines, or move to 200, 400 or 600 as port and flow demand changes. Drain is manual on this set (0.05-0.9 MPa setting range); automatic and differential-pressure drains are available. The 5 um W element suits finer-air duties - instrumentation, spray, small control valves - while the 40 um standard grade remains the choice for general machine air. This N code carries no gauge; gauge versions (square or external round, MPa, psi or bar) are order options if a local pressure reading is needed. PT thread is standard, with G(BSPP) and NPT as order options. Flow is published as curves, not a single rating - ask us to confirm sizing 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 0.05 - 0.9 MPa (7 - 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 (GC30008MLNW) FAQ
There is no single rated flow number to quote: AirTAC publishes G-series flow as curves. Tell us your working pressure and air demand and we will confirm the datasheet flow curve for this 300-size, 1/4 in set on request before you order.
Code N simply means the regulator is supplied without a gauge, for installations where pressure is read elsewhere on the machine. If operators need a reading at the set, order the gauge-equipped variant of the same 300-size configuration - square embedded or external round, in MPa, psi or bar scale.
