About the AirTAC GC300-08 FRL Unit (GC30008ALF1W)
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one set, so a single connection to the air line delivers filtered, regulated and oil-mist lubricated compressed air. This GC30008ALF1W is the 300 size with PT1/4 ports (PT is the standard thread), an automatic drain on the filter bowl, the fine 5 um filter element (W grade), the low-pressure (L) type regulator and an embedded square pressure gauge on an MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi); with the automatic drain, the regulator adjusts across 0.15-0.9 MPa (20-130 psi), and we can confirm the ceiling of the low-pressure type on request. Operating temperature is -5 to 70 C, non-freezing, with polycarbonate bowls on the 300 size.
This is a genuine AirTAC part sold by an authorised distributor. The G series spans sizes 200, 300, 400 and 600, with drain, filter grade, gauge scale and thread options (G/BSPP and NPT are catalogue choices alongside the PT standard). Flow for the GC series is published as performance curves rather than a single rated figure, so ask us to confirm sizing and any datasheet value on request before ordering.

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.
Model Code: AirTAC GC300-08 FRL Unit (GC30008ALF1W)
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| (blank) | No reverse-flow valve (the default). |
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 (GC30008ALF1W) Is Used
Laboratory pneumatic test rigs
Supplies finely filtered, regulated and lubricated air to bench-mounted leak and cycle-test rigs, where the 5 um element protects sensitive test fixtures from airborne particulate.
Robotics cell clamp fixtures
Conditions the air feeding weld-cell clamp and positioner actuators, pairing the 5 um grade with steady regulated pressure so control valves in the cell keep cycling cleanly.
Process pilot-actuated valve skids
Prepares instrument-quality air for pilot actuators on automated valve skids, with the automatic drain handling condensate and the low-pressure regulator holding a gentle set point.
Is the AirTAC GC300-08 FRL Unit (GC30008ALF1W) the Right Station?
Move through sizes 200, 300, 400 and 600 to match port size and flow demand; the 300 size here carries 1/4 inch PT ports. The W code fits the 5 um element instead of the 40 um standard, the right call where downstream valves and actuators see finer airborne dirt. This unit drains automatically; manual (M) and differential-pressure (blank) drains are alternatives. The embedded square gauge reads in MPa (scale 1), with psi (2) and bar (3) orderable, and G (BSPP) or NPT threads can be specified instead of PT.
Flow is published as curves, not a single rating, so share your line pressure and air demand and we will confirm the correct size 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 (GC30008ALF1W) FAQ
AirTAC publishes GC-series flow as performance curves rather than a single rated figure, so we do not quote one number on this page. Tell us your line pressure and downstream demand and we will confirm the correct size against the datasheet on request.
The blank code is the 40 um standard element for general plant air; the W code fits a 5 um element where finer particulate removal matters, such as for sensitive valves or instrumentation. Both grades are catalogue options on this same 300-size set.
