Airtac GFC Combination Unit GFC300C08MC1K
The AirTAC GFC Combination Unit GFC300C08MC1K 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 GFC300C08MC1K
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator plus a lubricator, so one model filters, regulates and lubricates compressed air. This GFC300C08MC1K is size 300 with PT1/4 ports, with the standard 40 um filter element, a hand-operated manual drain on the polycarbonate bowl, an external round MPa gauge, and a reverse (check) valve so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The GFC family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in PT, G (BSPP) or NPT thread, with 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and embedded square or optional round gauges. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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-C0 filter regulator and GL300-C0 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 GFC300C08MC1K Is Used
Pneumatic torque bench holding
On a fastening bench where a part must stay clamped between steps, the check valve holds downstream pressure through supply dips while the set filters, regulates and lubricates the clamp cylinder.
Workshop press fixture feed
Supplies a shop-floor pneumatic arbor press with regulated, oiled air; the operator drains the bowl at start of shift and reads set pressure on the external round MPa gauge.
Wire and cable cutting station
Prepares air for the clamp-and-cut cylinders of a cable processing station, with general 40 um filtration for the valves and a lubricator mist protecting the cylinder seals.
Is the Airtac GFC Combination Unit GFC300C08MC1K the Right Set?
Specify the K (check valve) version when trapped downstream pressure matters - clamps, chucks or any circuit that must not release on supply loss. Manual drain suits attended drops and gives the wider 0.05-0.9 MPa (7-130 psi) adjustment span, versus 0.15-0.9 MPa (20-130 psi) on auto/differential-drain versions. Size 300 with 1/4 inch PT ports covers typical machine supply; move to 200-600 to match demand, choose the round gauge scale (MPa, psi or bar) and PT, G or NPT thread at order.
Because AirTAC publishes flow as performance curves and not as one rated number, we cannot quote a flow figure here. Send us your application and we will confirm sizing against the datasheet before you order.
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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08MC1K FAQ
AirTAC does not publish a single rated flow for the G series - flow is given as performance curves that change with supply pressure and regulator setting. We therefore do not quote a figure here; send us your conditions and we will confirm the datasheet curve for this exact set before you order.
The K adds a reverse (check) valve in the filter-regulator, so downstream pressure is retained and backflow blocked if the upstream supply fails - valuable for clamping and holding duties. Everything else is the same: PT1/4 ports, 40 um filtration, manual drain with a 0.05-0.9 MPa (7-130 psi) adjustment range, round MPa gauge, two-unit filter-regulator plus lubricator format.
