AirTAC GFC300-15 Combination Unit (GFC30015F3W)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015F3W) 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 (GFC30015F3W)
The AirTAC GFC30015F3W is a two-unit compressed-air treatment set combining a filter regulator with a separate lubricator: it removes water and particulate, regulates downstream pressure and meters oil mist in one supply. The W suffix specifies the 5 um filter element instead of the 40 um standard, giving finer protection for sensitive valves and actuators. This size 300 unit has a PT1/2 in. port, differential-pressure drain, embedded square gauge scaled in bar, 1.0 MPa (145 psi) maximum working pressure and a 0.15-0.9 MPa (20-130 psi) regulator range.
This is a genuine AirTAC part from the G-series, offered in sizes 200 through 600 with 1/8 to 1 in. ports, G (BSPP) or NPT threads, a choice of drains and both filter grades. Flow is published as curves rather than a single rating, so ask us to confirm sizing and full 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 (GFC30015F3W) Is Used
Pilot valve protection
Supplying pilot-air to solenoid and process valves where the 5 um element keeps fine spool and orifice passages clear, while the regulator holds a stable set pressure and the lubricator serves the downstream cylinders.
Lab automation skid
Conditioning air on a laboratory or pilot-scale automation skid: clean, finely filtered air for grippers and small actuators, with regulated pressure for repeatable test conditions and oil mist for continuous cycling.
Paint and finishing booth air
Feeding spray guns and coating applicators, where finer filtration helps keep finish quality consistent, the regulator sets atomising pressure, and the lubricator is set for air motors and triggering valves.
Is the AirTAC GFC300-15 Combination Unit (GFC30015F3W) the Right Set?
Choose this code when your line needs the finer 5 um element - the standard code without W gives 40 um for general plant air. Size 300 with a PT1/2 in. port sits mid-range in the G-series; step to 400 or 600 for larger ports and more flow. The differential-pressure drain handles condensate automatically at high differential; manual (M) and automatic (A) drains are catalogue options. The square gauge reads in bar, with psi or MPa scales and the external round gauge available. PT is the standard thread, G (BSPP) and NPT are order options, and a bracket is included.
Flow is published as curves, not a single rated figure, so have us confirm sizing against the datasheet for 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 (GFC30015F3W) FAQ
Flow for the G-series is published as characteristic curves rather than a single rated number, so we do not quote a figure as a rating. Share your line pressure and demand and we will confirm the sizing from the datasheet on request before you place the order.
The W suffix changes only the filter grade, from the 40 um standard to 5 um, giving finer protection for precision valves and instruments. Everything else stays the same: size 300, PT1/2 in. port, differential-pressure drain, square bar-scale gauge, lubricator included and 1.0 MPa maximum working pressure.
