AirTAC GC300-08 FRL Unit (GC30008AC1WK)
The AirTAC AirTAC GC300-08 FRL Unit (GC30008AC1WK) 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 (GC30008AC1WK)
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one set. This configuration is size 300 with 1/4 in PT ports. The filter bowl drains automatically, the element is the fine 5 um (W) grade, a round pressure gauge on MPa scale is included, and a reverse (check) valve (K) is fitted so downstream air is not pushed back through the set when upstream pressure is lost. The regulator adjusts from 0.15 to 0.9 MPa (20 to 130 psi) in this automatic-drain configuration.
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the bowls are polycarbonate (PC) at this size. G-series flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures 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. 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 (GC30008AC1WK)
| 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 (GC30008AC1WK) Is Used
CNC machining centre
Prepares the air feeding a machining centre's tool changer, clamps and ejection cylinders: 5 um filtration ahead of the components, a regulated set pressure and a light oil mist, with the check valve holding the downstream side during upstream service.
Carton-sealing line
Supplies the pneumatic cylinders and grippers on a carton erecting and sealing conveyor, where the automatic drain keeps condensate out of the supply without a manual blow-down stop in the shift.
Solenoid valve manifold supply
Conditions air ahead of a solenoid-valve manifold on an assembly station so the valves and the cylinders they switch see filtered, regulated and lubricated air at a stable set pressure.
Is the AirTAC GC300-08 FRL Unit (GC30008AC1WK) the Right Station?
Size 300 with 1/4 in PT ports sits in the middle of the G range (200, 300, 400, 600); step up or down a size if your machine needs larger or smaller ports and flow. Drain is automatic here - choose M (manual) if your operators prefer controlled blow-down, or leave the code blank for the differential-pressure default. The 5 um W element suits finer air preparation; the standard element is 40 um. Gauge scale options are MPa (C1), psi (C2) and bar (C3), or the embedded square gauge when no gauge code is given. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options. Flow is published 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 (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 (GC30008AC1WK) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number here. Send us your application details and we will confirm the datasheet flow curve and sizing for GC30008AC1WK on request.
K means a reverse (check) valve is fitted to this set, so downstream air is not pushed back through the units when upstream pressure is lost. The same set without K leaves the air path without that check function.
