AirTAC GC300-10 FRL Unit (GC30010LN)
The AirTAC AirTAC GC300-10 FRL Unit (GC30010LN) 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-10 FRL Unit (GC30010LN)
The AirTAC GC series is a three-unit F.R.L.: separate air filter, pressure regulator and lubricator that together remove water and particulate, hold a set downstream pressure and add oil-mist lubrication to compressed air. This GC30010LN is the size 300 configuration with PT3/8 ports, the low-pressure (L) regulator type, a differential-pressure drain on the filter bowl, the standard 40 um filter element and no gauge. Bowls at size 300 are polycarbonate; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus automatic or manual drains, a 5 um element (W), gauges in MPa, psi or bar scales, G or NPT threads and an optional bracket. AirTAC publishes flow for the G series as curves rather than one rated figure, so we confirm flow and datasheet details for your application 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.

| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010LN) Is Used
Packaging line actuator supply
Feeding clean, regulated and lubricated air to the cylinders that drive carton forming, filling and sealing heads on a packaging machine, with the low-pressure regulator set to the pressure the machine was built for.
Paint spray booth conditioning
Conditioning the atomizing-air feed at a finishing booth so the painter dials in a low, stable setting while the filter bowl strips water that would otherwise ruin the finish.
Process skid valve actuation
Supplying filtered, lubricated air to quarter-turn pneumatic actuators on a process skid, keeping the supply line conditioned ahead of the solenoid valves.
Is the AirTAC GC300-10 FRL Unit (GC30010LN) the Right Station?
Size 300 is the mid-range body: the PT3/8 ports and 300 frame suit lines whose air demand sits between the smaller size 200 class and the larger 400/600 sets, so step up or down a size when the demand calls for it, not just because the pipe has a certain bore. The L in the code marks the low-pressure regulator type; we confirm its adjustment range against the datasheet before you order, since the standard type adjusts 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain fitted here.
Other real choices on this family: automatic (A) or manual (M) drain in place of the differential drain, a 5 um element (W) instead of the 40 um standard, an embedded square or external round gauge in MPa, psi or bar scales (this build has none), G (BSPP) or NPT threads in place of PT, and an optional bracket. AirTAC publishes flow as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010LN) FAQ
AirTAC publishes G-series flow as selection curves rather than a single rated figure, so no honest l/min or SCFM number can be quoted here. Send us your line pressure and air demand and we will confirm the size 300 fit - or whether 200, 400 or 600 is the better step - straight from the datasheet before you order.
L selects the low-pressure regulator type and N means the set is built without a gauge; the regulator can still be set to the pressure your machine needs. If you want a visual reference, other GC300 variants carry an embedded square or external round gauge in MPa, psi or bar scales - ask us to confirm availability for your build.
