Airtac GFC Combination Unit GFC300C08MF1K
The AirTAC GFC Combination Unit GFC300C08MF1K 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 GFC300C08MF1K
The GFC is AirTAC's two-unit air preparation set: a filter-regulator plus a separate lubricator, covering filtration, pressure regulation and oil-mist lubrication in one part number. This configuration is the size 300 set with PT1/4 ports (PT thread), a manual drain on the filter bowl, the standard 40 um filter element, the embedded square pressure gauge scaled in MPa (F1) and a trailing K, meaning a reverse (check) valve is fitted. The bowls are polycarbonate at this size, maximum working pressure is 1.0 MPa (145 psi), and the manual-drain regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part from the G series, available in sizes 200, 300, 400 and 600 with ports from 1/8 in. to 1 in. and in PT, G (BSPP) and NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet and sizing for your application 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-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 GFC300C08MF1K Is Used
Lab autoclave and washer pneumatic circuits
Conditions the compressed air feeding the door clamps and valve actuators on laboratory washers and sterilizer support equipment, with clean regulated air and light lubrication.
Pneumatic valve manifolds on process skids
Supplies the pilot air for process valve actuators on a skid, keeping moisture and particles out of the pilot valves while the regulator pins the pilot pressure.
High-cycle stamping press feeders
Prepares air for the roll-feed and clamp cylinders on a press feed line, where the check valve supports the downstream circuit and the lubricator services the actuator seals.
Is the Airtac GFC Combination Unit GFC300C08MF1K the Right Set?
Size 300 with 1/4 in. ports is the middle step of the G range; step to 200 for small circuits or 400/600 for larger ones, and pick the port from your piping rather than from a quoted flow number. Drain choices are differential-pressure (default), automatic or manual - this unit is manual, so an operator vents the bowl and the 0.05-0.9 MPa regulating window applies. No W means the standard 40 um element; the 5 um grade is the finer alternative. The K suffix fits a reverse (check) valve; drop the K for the set without it. Gauge: embedded square, MPa scale (F1), with the external round gauge and psi/bar scales as options. PT is the standard thread; G and NPT are orderable thread options. Flow appears only as curves, 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-C0 filter regulator on its own.
Airtac GFC Combination Unit GFC300C08MF1K FAQ
Flow for the G series is published as curves rather than a single rated figure, so the honest route is application matching: send us your line pressure, port size and downstream demand, and we will confirm the sizing from the datasheet on request.
K is the AirTAC code for a reverse (check) valve fitted in the unit, which permits reverse flow from the downstream side when upstream pressure is removed. Drop the K from the code if you want the same two-unit set without the check valve.
