About the Airtac GC FRL Unit GC300C08NW
The GC300C08NW is a genuine AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator ordered as one set. This version is size 300 with 1/4 in PT ports, the 5 um fine filter element (W code), differential-pressure drain on the filter bowl, no gauge fitted and no reverse valve. It removes water and fine particulate, holds the regulated downstream pressure and meters oil mist into the air line.
It is a genuine AirTAC part, one of a G-series range running from size 200 to 600 with 1/8 in to 1 in ports, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um grades, gauge options and G (BSPP) or NPT threads. Max working pressure is 1.0 MPa (145 psi); temperature range is -5 to 70 C, non-freezing. We confirm flow and other datasheet figures on request, since flow is published as curves rather than a single rating.

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.

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-C0 filter, GR300-C0 regulator and GL300-C0 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 GC FRL Unit GC300C08NW Is Used
CNC machining centre clamping
Air prep for pneumatic clamps and tool-change cylinders on a CNC machining centre, with the 5 um element catching fine particulate before it reaches control valves.
Electronics assembly pick-and-place
Conditioning the supply to vacuum ejectors and pick-and-place heads on benchtop electronics assembly stations, where the 5 um grade and steady regulated pressure are the job.
Textile machine cylinder circuits
Filtering, regulating and lubricating the air feeding dobbies and cylinder drives on textile machinery from a 1/4 in point-of-use station.
Is the Airtac GC FRL Unit GC300C08NW the Right Station?
Move up through sizes 200, 300, 400 and 600 as flow demand and required port size grow; size 300 with 1/4 in PT ports covers compact machine supply circuits. With the differential-pressure drain in this code the regulator adjusts over 0.15-0.9 MPa (20-130 psi); a manual-drain variant extends the range to 0.05-0.9 MPa (7-130 psi). The W code here selects the 5 um fine element rather than the 40 um standard, worth specifying when downstream spool valves or ejectors need cleaner air. No gauge is fitted (N code); round or square gauges with MPa, psi or bar scales are orderable. Thread is PT as standard with G (BSPP) and NPT as options, and a bracket is included by default. Flow appears only as curves, so ask us to confirm sizing from the datasheet before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C0 regulator with a GF300-C0 filter on that branch.
Airtac GC FRL Unit GC300C08NW FAQ
We do not state a single rated flow because AirTAC publishes G-series flow as curves, not one figure. Tell us your working pressure, downstream air demand and allowable pressure drop, and we will confirm the correct size from the datasheet on request.
The W code in GC300C08NW selects the 5 um filter element instead of the 40 um standard grade, a choice made when downstream equipment needs finer filtration. Drain on this code is differential-pressure; automatic (A) or manual (M) variants are also available in the series.
