AirTAC GFC300-15 Combination Unit (GFC30015C1W)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015C1W) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/2" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015C1W)
The AirTAC GFC30015C1W is a two-unit air treatment set: a filter regulator plus a lubricator in one order. The W suffix specifies the 5 um filter element instead of the 40 um standard, giving finer particulate removal ahead of sensitive pneumatic equipment. This 300-size set has PT1/2 ports, a differential-pressure drain and a round pressure gauge on an MPa scale.
This is a genuine AirTAC part. The G-series two-unit set spans 200, 300, 400 and 600 sizes with options for port, thread, drain type and filter grade. Flow is published as curves rather than a single rating, so 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 set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-15 filter regulator and GL300-15 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC300-15 Combination Unit (GFC30015C1W) Is Used
Laboratory pneumatic test bench
On a lab test bench running pneumatic sample fixtures, the 5 um element keeps fine particulates out of precision test cylinders and transducers, while the regulator sets test pressure and the lubricator services the clamping actuators.
Electronics assembly pick-and-place
Supplying SMT pick-and-place modules on an electronics line, the set's 5 um filtration protects the fine air bearings and vacuum ejectors, with regulation and oil mist for the placement head cylinders from one PT1/2 feed.
Hospital-style pneumatic tube station
Feeding a pneumatic tube transport station's diverters and door actuators, the set delivers finely filtered, regulated and lubricated air, helping the 5 um element limit wear on the small-bore transfer valves.
Is the AirTAC GFC300-15 Combination Unit (GFC30015C1W) the Right Set?
Pick the W (5 um) grade over the standard 40 um when the downstream equipment needs finer filtration, such as instrumentation or precision cylinders. The 300 size with PT1/2 ports suits mid-range supply lines; step to 400 or 600 for larger ports and more flow. Drain is differential-pressure here, with automatic (A) and manual (M) versions available.
The C1 configuration carries a round gauge with an MPa scale. Thread is PT as standard, with G (BSPP) and NPT as catalogue options, and the mounting bracket is included. 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 (PT1/2" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-15 filter regulator on its own.
AirTAC GFC300-15 Combination Unit (GFC30015C1W) FAQ
There is no single rated flow to quote: AirTAC publishes G-series flow as performance curves rather than one figure. Share your operating pressure and demand and we will confirm the flow data from the datasheet on request.
The W suffix changes the filter element from the standard 40 um to 5 um, for finer particulate removal ahead of sensitive equipment. The rest of the decode is unchanged: two-unit filter regulator plus lubricator, 300 size, PT1/2 ports, differential-pressure drain, and a round MPa-scale gauge.
