About the AirTAC GC300-08 FRL Unit (GC30008AC1W)
GC30008AC1W is a genuine AirTAC GC three-unit F.R.L. combination: a separate GF air filter, GR pressure regulator and GL lubricator assembled into one conditioned-air train, with the W option selecting a 5 um filter element instead of the 40 um standard. This 300-size set is threaded PT1/4 (1/4 in), has an automatic drain on the filter bowl and a round external pressure gauge scaled in MPa. The polycarbonate bowls are rated for compressed air at up to 1.0 MPa (145 psi) inlet and -5 to 70 C, and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi).
The GC series is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, 40 um standard or 5 um (W) elements, differential-pressure, automatic or manual drains, embedded square or round external gauges scaled in MPa, psi or bar, and PT, G or NPT threads. AirTAC publishes flow for these units as characteristic curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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 (GC30008AC1W)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|

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 (GC30008AC1W) Is Used
Control-valve pilot air on a water-treatment skid
Feeds pilot air to the pneumatically piloted control valves on a water-treatment skid; the 5 um element suits the small pilot orifices and the automatic drain handles condensate on a continuously running skid.
PCB handling cylinders
Conditions the air to the handling cylinders and grippers on a PCB assembly line, where the finer element supports the small pilot valves that sequence the motions.
Logic valves on an automated test stand
Supplies the timer and logic valves on an automated functional-test stand with filtered, regulated and lubricated air, with the MPa gauge letting the technician verify set pressure at the stand.
Is the AirTAC GC300-08 FRL Unit (GC30008AC1W) the Right Station?
The W in this code is the filter-grade choice: 5 um instead of the 40 um standard, worth taking when downstream components have fine clearances. Everything else matches the GC30008AC1 set: 300 size at PT1/4, automatic drain, regulator range 0.15-0.9 MPa (20-130 psi) and a round external gauge on an MPa scale; psi (2) and bar (3) scales, other drain types and G or NPT threads are catalogue alternatives to the PT standard.
Flow is published as curves, not a single rating, so share your pressure and consumption points and we will confirm sizing against the datasheet before you order.
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 (GC30008AC1W) FAQ
AirTAC publishes GC flow as characteristic curves rather than a single rated figure, so no one l/min value is stated here. Tell us your working pressure and required flow and we will confirm sizing from the datasheet on request.
W upgrades the filter element from the 40 um standard to 5 um, which suits piloted valves, instrumentation and other components sensitive to fine particles. Drain type, gauge scale and thread (PT standard, G or NPT) remain selectable within the GC family.
