Airtac GFC Combination Unit GFC300C08MNK
The AirTAC GFC Combination Unit GFC300C08MNK 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 GFC300C08MNK
GFC300C08MNK is an AirTAC GFC two-unit set: a GFR300 filter regulator paired with a GL300 lubricator. Decoded: 300 size, PT1/4 ports (PT standard; G and NPT order options), manual-drain bowl, standard 40 um filter element, no gauge (N), and a reverse/check valve fitted in the regulator section (trailing K). Maximum inlet pressure is 1.0 MPa (145 psi); with the manual drain the regulator range is 0.05-0.9 MPa (7-130 psi). Temperature is -5 to 70 C, non-freezing, and both bowls are polycarbonate at the 300 size.
This is a genuine AirTAC part supplied by us as a distributor. The GFC series spans sizes 200 through 600 with ports from 1/8 inch to 1 inch, and options for gauge, drain type, filter grade, thread and check valve. Flow for this size is published as curves rather than a single rating, so ask us to confirm the datasheet and your sizing on request 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-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 GFC300C08MNK Is Used
Palletiser layer-forming cylinders
Conditions air for the pushers and clamps on a palletiser layer-forming station, with the check-valve option fitted in the regulator section and the manual drain used at scheduled maintenance.
Fixture clamping on an air press
Feeds the swing clamps on a pneumatic press fixture, holding the regulated clamping pressure set at commissioning, with the lubricator misting the clamp cylinder seals.
Sorting diverter on a parcel line
Prepares the air supply for diverter and stopper actuators on a parcel sorting conveyor, with the 40 um element removing water and dirt ahead of the line's directional valves.
Is the Airtac GFC Combination Unit GFC300C08MNK the Right Set?
This is the gaugeless, standard-grade 300-size two-unit set with the K reverse (check) valve added; order GFC300C08MN for the same unit without the valve. Port and flow: PT1/4 here, with 400 and 600 sizes for larger demand. Drain is manual, emptied by hand, versus automatic or differential-pressure alternatives. Filter grade is the 40 um standard; specify W for 5 um. Thread is PT as standard, with G (BSPP) and NPT available to order, and brackets follow the catalogue options. Because flow is published as curves rather than a single rated figure, 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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08MNK FAQ
AirTAC publishes 300-size flow as curves rather than one rated figure, so there is no single number to quote. Give us your working pressure and air consumption and we will confirm the sizing from the datasheet on request.
Only the trailing K: it adds a reverse (check) valve to the regulator section. Both are 300-size two-unit sets with PT1/4 ports, manual drain, standard 40 um element, standard regulator type and no gauge; gauge-equipped variants are orderable separately.
