AirTAC GFC300-15 Combination Unit (GFC30015C1)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015C1) 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 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015C1)
The AirTAC GFC30015C1 is a two-unit air treatment set: a filter regulator paired with a lubricator, so one order covers filtration, pressure regulation and oil-mist lubrication of your compressed air line. This 300-size set has PT1/2 ports, the standard 40 um filter element, a differential-pressure drain on the filter bowl, and a round pressure gauge on an MPa scale fitted to the regulator.
This is a genuine AirTAC part. The G-series set is offered in 200, 300, 400 and 600 sizes with a choice of port, thread, drain type and filter grade; flow figures are published as curves rather than a single rating, so we confirm datasheet numbers 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 (GFC30015C1) Is Used
CNC machining centre air supply
Mounted ahead of a CNC machining centre's air manifold, the set filters machining debris and condensate from the shop supply, holds a steady regulator setting for actuator circuits, and meters oil mist to spindle clamps and tool-changer cylinders.
Packaging line conveyor controls
On a packaging conveyor line, the filter regulator keeps sorting and stopper cylinders supplied with clean air at a stable pressure while the lubricator feeds the pneumatic grippers that handle cartons all shift.
Textile plant loom air ring
Feeding the pneumatic jet and doffing circuits of an air-jet loom, the two-unit set removes line moisture and lint-laden particles, regulates branch pressure, and lubricates the loom's cylinder banks from one PT1/2 connection.
Is the AirTAC GFC300-15 Combination Unit (GFC30015C1) the Right Set?
Start with size and port: the 300 size with 1/2" PT ports suits mid-range supply lines, and stepping up to 400 or 600 increases port size and flow capacity. The 40 um element is the standard grade; choose the W suffix for a 5 um element where finer filtration is needed. Drain is differential-pressure here, with automatic (A) and manual (M) versions available in the family.
This C1 configuration carries a round gauge with an MPa scale. Thread is PT as standard, with G (BSPP) and NPT available 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 (GFC30015C1) FAQ
AirTAC publishes flow for the G-series as performance curves, not as a single rated figure, so there is no one flow number we can quote. Tell us your application and line conditions and we will confirm the flow and sizing data from the datasheet on request.
GFC is the two-unit family (filter regulator plus lubricator), 300 is the size, 15 is the 1/2" port, and C1 means a round external pressure gauge on an MPa scale. The default configuration also carries the standard 40 um filter element and a differential-pressure drain; 5 um (W) and automatic or manual drain variants are available in the same family.
