Airtac GFC Combination Unit GFC300C15MC1K
The AirTAC GFC Combination Unit GFC300C15MC1K 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 GFC300C15MC1K
The GFC two-unit set pairs a filter-regulator with a lubricator: the front unit removes water and particulate and regulates downstream pressure, while the lubricator feeds an oil mist into the line. The K in this code adds a reverse-flow check valve, so air is held downstream if supply pressure is lost. This 300-size configuration has PT1/2 (1/2 in) ports, a manual drain, the standard 40 um filter element and a round gauge scaled in MPa. Maximum working pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, offered in 200, 300, 400 and 600 sizes with a choice of ports, PT/G/NPT threads, drain types, 40 um or 5 um filter grades and the check-valve option. Flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details for your application before ordering.

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 GFC300C15MC1K Is Used
Actuator hold-circuits on process skids
Keeps pneumatically actuated process valves in position during a supply interruption, with the check valve holding pressure on the downstream side.
Press-safety clamp circuits
Maintains clamped state on safeguarding cylinders at a stamping press if the plant air line drops, supporting a controlled hold rather than an instant release.
Blow-off stations on filling lines
Conditions and regulates air to cleaning and blow-off nozzles, with the manual drain bled each shift in dusty filling-hall conditions.
Is the Airtac GFC Combination Unit GFC300C15MC1K the Right Set?
Choose the K suffix when downstream equipment must stay pressurised if the supply drops - the check valve blocks back-flow toward the source. Otherwise the decode is standard for this size: 300 body, port code 15 = 1/2 in, PT thread as standard with G and NPT to order, manual drain (M) against differential-pressure or automatic (A), and 40 um filtration standard or 5 um with W. The gauge is the external round type, MPa scale, with square gauges and psi or bar scales as alternatives. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 GFC300C15MC1K FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote a number here. Share your line pressure, port size and flow requirement and we will confirm the sizing against the datasheet curves on request.
K specifies a reverse-flow (check) valve fitted in the unit: downstream pressure is retained if the upstream supply is lost. Without the K, the same set is ordered as GFC300C15MC1, so pick the suffix based on whether hold-on-failure matters in your circuit.
