AirTAC GC300-08 FRL Unit (GC30008AF1W)
The AirTAC AirTAC GC300-08 FRL Unit (GC30008AF1W) 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 PT1/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC300-08 FRL Unit (GC30008AF1W)
GC30008AF1W is a three-unit AirTAC G-series F.R.L. combination - separate filter, regulator and lubricator for 1/4 in (PT1/4) ports - specified with the fine 5 um filter element. Combined with the automatic-drain bowl and the embedded square gauge scaled in MPa, this configuration gives finer particle removal than the standard element ahead of regulation, self-emptying condensate handling, and metered oil mist for downstream equipment.
This is a genuine AirTAC part. The G series is available in 200, 300, 400 and 600 sizes, carries compressed air only up to 1.0 MPa (145 psi) working pressure at -5 to 70 C, and uses polycarbonate bowls at the 300 size. Flow is published as curves rather than a single rating, so we confirm flow and other 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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 (GC30008AF1W)
| 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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 (GC30008AF1W) Is Used
High-cycle cylinder banks on assembly machines
Multi-station assembly machines run cylinders thousands of times per shift; the 5 um element reduces fine particle wear on seals and bores while the lubricator maintains the oil film.
Pneumatic circuits on test and gauging benches
Bench rigs with air-operated clamps, comparators and actuation fixtures behave more repeatably on finer-filtered air, and the MPa-scale square gauge supports documented test setups.
Air-motor drives on winding and unwinding stands
Air motors on roll-winding stands need continuous lubrication and tolerate grit poorly; this set delivers oiled, finely filtered air while the automatic drain handles condensate through long runs.
Is the AirTAC GC300-08 FRL Unit (GC30008AF1W) the Right Station?
Pick the W suffix when the 40 um standard element is too coarse for the components you are protecting - the 5 um option is coded directly in the part number. The rest of this code is the mid-range 300 size with 1/4 in PT ports, automatic drain (manual and differential-pressure variants exist, with 0.15-0.9 MPa / 20-130 psi adjustment for automatic and differential drains) and the embedded square MPa gauge; psi or bar scales and an external round gauge are catalogue options, as are G (BSPP) and NPT threads in place of the PT standard. Because flow is published as curves rather than a single rating, ask us to confirm the 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 (GC30008AF1W) FAQ
AirTAC does not publish a single rated flow for the G series - performance is given as characteristic curves, so any one-number claim would be an estimate. Send us your duty flow and pressure and we will confirm the fit against the datasheet curves on request before you order.
Choose the 5 um W element when the downstream equipment has close-tolerance valves, fine seals or repeatability requirements that coarser 40 um filtration does not suit; keep 40 um for general-purpose shop air. Both grades are catalogue options across the GC filter, filter-regulator and F.R.L. families.
