AirTAC GC300-08 FRL Unit (GC30008AC2WK)
The AirTAC AirTAC GC300-08 FRL Unit (GC30008AC2WK) 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 (GC30008AC2WK)
The GC series is a three-piece F.R.L. set: separate air filter, pressure regulator and lubricator working together. This configuration is size 300 with 1/4 in PT ports, an automatic-drain filter bowl and the fine 5 um (W) element. A round pressure gauge on psi scale is included, and the K code means a reverse (check) valve is fitted so downstream air is not pushed back through the set on loss of upstream pressure. With automatic drain the regulator adjusts from 0.15 to 0.9 MPa (20 to 130 psi).
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), working temperature is -5 to 70 C (non-freezing), and the bowls are polycarbonate (PC) at this size. The GC range spans sizes 200 to 600 with manual or differential-pressure drain alternatives, 40 um standard elements, other gauge scales and G or NPT threads. Flow is published as curves, not a single rating - we confirm 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 (GC30008AC2WK)
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 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. |

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 (GC30008AC2WK) Is Used
Robotic welding cell
Prepares air for a weld cell's gun-clamp and positioner actuators, with 5 um filtration ahead of the valves and the check valve keeping the downstream side charged while the upstream supply is isolated.
Pick-and-place module array
Supplies a bank of pneumatic pick-and-place modules on an automation panel, giving every module filtered, regulated and lubricated air from one 1/4 in PT set pressure point.
Laboratory automation skid
Conditions the compressed air serving lab automation actuators and test fixtures, where the 5 um element and automatic drain keep the supply clean between service intervals.
Is the AirTAC GC300-08 FRL Unit (GC30008AC2WK) the Right Station?
Size 300 with 1/4 in PT ports suits mid-range machine air supplies; move to 200, 400 or 600 as your port and flow needs change. This unit has the automatic drain - pick M for manual, or blank for differential-pressure draining. The 5 um W element is the finer choice for valves and instruments; the standard element is 40 um. The C2 code gives a round gauge in psi; C1 (MPa) and C3 (bar) are the other scales. Thread is PT as standard with G (BSPP) and NPT as options, and K adds the reverse valve you see in this code. 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 (GC30008AC2WK) 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 line details and we will confirm the datasheet flow curve and sizing for GC30008AC2WK on request.
W in the code selects the fine 5 um filter element instead of the standard 40 um grade, which suits supplies feeding directional valves, instruments and other components that want cleaner air. Choose the blank code for 40 um on general-duty cylinder supplies.
