Airtac GFC Combination Unit GFC300C08MF1WK
The AirTAC GFC Combination Unit GFC300C08MF1WK 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 GFC300C08MF1WK
GFC300C08MF1WK is an AirTAC GFC two-unit set combining a GFR300 filter regulator with a GL300 lubricator. It decodes to the 300 size with PT1/4 ports (PT standard; G and NPT available as order options), a manual-drain bowl, a 5 um (W) filter element, a square MPa gauge and, thanks to the trailing K, a reverse/check valve fitted to the regulator section. 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 range is -5 to 70 C, non-freezing, and both 300-size bowls are polycarbonate.
This is a genuine AirTAC part supplied by us as a distributor. The GFC series runs from size 200 to 600 with ports from 1/8 inch to 1 inch, and options for drain type, filter grade, gauge style and scale, thread and check valve. Flow for this size is given as curves in the catalogue, not as a single rating, so ask us to confirm the datasheet and 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 GFC300C08MF1WK Is Used
Robot gripper valve panel
Prepares air for the gripper and tool-changer valve panel on a pick-and-place robot cell, with the check-valve option fitted in the regulator section and the manual drain for scheduled purging.
Spray-booth gun feed
Conditions the air line to spray guns in a finishing booth: the 5 um element and regulation keep the atomising supply steady while the lubricator is set only where the gun design calls for it.
Bottle-capping machine cylinders
Feeds the capping and indexing cylinders on a bottling conveyor, with regulated pressure to the actuators and oil mist protecting the cylinder seals over repeated cycles.
Is the Airtac GFC Combination Unit GFC300C08MF1WK the Right Set?
The GFC pair keeps filter regulator and lubricator separate for independent service. This code is the 300 size on PT1/4; move to 400 or 600 for bigger ports and flow or to 200 for compact panels. The K suffix fits a reverse (check) valve; delete the K for the plain standard unit. Drain is manual here, with automatic and differential-pressure versions available. Filter grade is the fine 5 um (W) versus the 40 um standard. The square gauge reads in MPa; psi and bar scales exist. Thread is PT as standard, G (BSPP) or NPT to order. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing against your line 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 GFC300C08MF1WK FAQ
There is no single rated flow figure to quote: AirTAC publishes the 300-size performance as flow curves. Send us your pressure and demand details and we will confirm the right sizing from the datasheet on request.
K means a reverse (check) valve is fitted to the regulator section; the identical unit without K is GFC300C08MF1W. Everything else decodes the same: 300 size, PT1/4 ports, manual drain, 5 um element, square MPa gauge and standard regulator type.
