About the AirTAC GC300-15 FRL Unit (GC30015F1W)
The GC30015F1W is an AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator assembled as one 3-piece set. The W in the code selects the fine 5 um filter element in place of the standard 40 um, so the air reaching your equipment is filtered to a tighter particulate grade before regulation and oil-mist lubrication. This configuration is size 300 with PT1/2 ports, uses the default differential-pressure drain on the filter bowl, and includes the embedded square gauge reading in MPa; with a differential-pressure drain the regulator range is 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The G-series combination is available in sizes 200, 300, 400 and 600 with PT, G (BSPP) or NPT threads and options for drain type, filter grade, gauge scale and check valve; maximum inlet pressure is 1.0 MPa (145 psi) and temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we confirm datasheet and flow 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.

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: GF300-15 filter, GR300-15 regulator and GL300-15 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 GC300-15 FRL Unit (GC30015F1W) Is Used
Laboratory pneumatic fixtures
Supplying air to laboratory test fixtures and clamping devices, where the 5 um element keeps fine particulate out of precision pneumatic components and the regulator holds a steady test pressure.
Semiconductor jig and clamp circuits
Conditioning air for jig-clamp cylinders on electronics assembly equipment, where finer 5 um filtration protects small-bore valves and the lubricator maintains cylinder seal life.
Paint and coating spray-air prep
Prepping supply air ahead of a spray or coating application, combining 5 um particulate removal with regulated pressure and oil misting per the line's setup.
Is the AirTAC GC300-15 FRL Unit (GC30015F1W) the Right Station?
Pick this code over GC30015F1 when the application needs the 5 um element - for example air feeding sensitive pneumatic instrumentation or fine sealing surfaces - while keeping the size 300, PT1/2 footprint and the embedded square MPa gauge. The drain is the differential-pressure default; specify M (manual) or A (automatic) in the equivalent code if your maintenance regime suits that better. Step the size (200/300/400/600) and port (1/8" to 1") to match your line's flow curve and pipe diameter. Thread is PT as standard, with G (BSPP) and NPT versions plus the mounting bracket available as catalogue options, and gauge scales in psi or bar on other codes.
Because AirTAC publishes flow only as curves with no single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC GC300-15 FRL Unit (GC30015F1W) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote a number here. Provide your operating pressure and required air consumption and we will confirm the flow figures from the datasheet for this size 300, PT1/2 combination before you order.
The W code selects the optional 5 um element, suited to applications that need finer particulate removal than the 40 um standard grade - such as instrumentation, fine valves or coating processes. If general supply-air duty is all that is required, the non-W GC30015F1 uses the 40 um element in the same size 300, PT1/2 configuration.
