Airtac GFC Combination Unit GFC300C15C1
The AirTAC GFC Combination Unit GFC300C15C1 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC300C15C1
GFC300C15C1 is a two-piece AirTAC G-series air-treatment set: a filter regulator plus a lubricator, so it removes water and particulate, regulates downstream pressure and adds oil mist in one combined order. This configuration is sized 300 with a PT1/2 port (PT thread as standard), a differential-pressure drain, the standard 40 um filter element and a round pressure gauge with MPa scale. Downstream regulation covers 0.15-0.9 MPa (20-130 psi) with this drain type; the set carries compressed air at up to 1.0 MPa (145 psi) and works from -5 to 70 C (non-freezing). Both bowls on this 300 size are PC (polycarbonate).
This is a genuine AirTAC part sold by a distributor for the US market. The G-series spans 200, 300, 400 and 600 sizes with port options from 1/8 to 1 inch, plus drain choices, 5 um (W) elements, gauge types and scales, G (BSPP) and NPT threads and a reverse valve where the code carries K. AirTAC publishes flow as curves rather than a single rating, so send us your application details and we will confirm sizing and 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-C1 filter regulator and GL300-C1 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 GFC Combination Unit GFC300C15C1 Is Used
CNC machining centers
Supplies filtered, pressure-regulated and lubricated air to the tool-changer and clamping cylinders on a machining center, with a single 1/2 inch supply point feeding the machine's pneumatic circuit.
Packaging and case-sealing lines
Feeds the flap-fold and carton-sealing cylinders on a packaging line, keeping water and pipe scale out of the valves while the lubricator maintains the cylinders that cycle all shift.
Pneumatic assembly stations
Conditions the bench supply for impact wrenches, nutrunners and air ratchets at an assembly station, where regulated pressure protects the tools and oil mist keeps vanes and bearings running.
Is the Airtac GFC Combination Unit GFC300C15C1 the Right Set?
The 300 size with a 1/2 inch PT port is the mid-range step in the G-series; if your flow curve points higher or lower, the same functions are available in 200, 400 and 600 sizes with ports from 1/8 to 1 inch. This unit uses the differential-pressure drain; specify A for an automatic drain or M for manual if your duty cycle calls for it. The standard element is 40 um, and the W option gives a 5 um element for finer filtration. A round gauge with MPa scale is fitted here; other gauge types and scales are catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a 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 (See datasheet 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C15C1 FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
GFC is a two-piece set: a filter regulator plus a lubricator, giving filtration, regulation and lubrication in two bodies. The GC three-unit F.R.L. uses separate filter, regulator and lubricator bodies; choose it if you want to service or position each stage independently.
