Airtac GFC Combination Unit GFC300C08F1
The AirTAC GFC Combination Unit GFC300C08F1 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 GFC300C08F1
The GFC series is AirTAC's two-unit air-treatment set: a filter regulator paired with a lubricator, providing filtration, pressure regulation and oil-mist lubrication from a single set. This GFC300C08F1 is the size 300 body on a PT1/4 port. The filter bowl uses the differential-pressure drain (the default) with the standard 40 um element, and the regulator carries the embedded square pressure gauge with MPa scale, adjusting between 0.15-0.9 MPa (20-130 psi). It is for compressed air only, rated to 1.0 MPa (145 psi) inlet and -5 to 70 C.
This is a genuine AirTAC part. The G series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 inch to 1 inch, and drain type, filter grade, gauge style and scale, and thread form (PT as standard, with G and NPT as catalogue options) are selectable. AirTAC publishes flow as characteristic curves rather than a single rated figure, so we confirm flow and other datasheet numbers 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 GFC300C08F1 Is Used
Assembly bench air tools
Feeding impact drivers, nutrunners and air ratchets at an assembly workbench: the set cleans and regulates the 1/4 inch drop and mists oil to the tool motors through their quick couplings.
Plant ring-main takeoffs
Conditioning the air at a takeoff from a factory ring main: one two-unit set gives the branch its own 40 um filtration, a set line pressure on the square gauge, and lubrication for the tools and cylinders on that drop.
Conveyor diverter stations
Supplying the divert and stopper cylinders along a parcel or tote conveyor line, where the regulator holds the set pressure for consistent actuation and the lubricator feeds the cylinder seals.
Is the Airtac GFC Combination Unit GFC300C08F1 the Right Set?
Size 300 on a PT1/4 port suits 1/4 inch branches serving downstream cylinders, valves and air tools; the same set is available in size 400 or 600 on larger ports if demand grows. This version keeps the standard 40 um element - choose the W suffix instead if the downstream equipment needs 5 um filtration.
Drain is the differential-pressure default, with automatic and manual drain options; a manual-drain version widens the regulator's lower adjustment limit to 0.05 MPa. The regulation range on this differential-drain set is 0.15-0.9 MPa (20-130 psi), read on the embedded square MPa gauge; a round gauge, or a square gauge in psi or bar scale, can be ordered. Thread is PT as standard, with G (BSPP) and NPT as orderable options. Flow is published as curves, not a single rating, 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 GFC300C08F1 FAQ
AirTAC publishes flow for the G series as characteristic curves rather than a single rated figure, so we do not quote a rated flow here. Share your line pressure, downstream consumption and allowable pressure drop, and we will confirm the correct size and the curve data from the datasheet on request.
The F in this code selects the embedded square gauge with MPa scale (1). A round gauge is the alternative (code C), and scales of psi (2) or bar (3) are also available. So GFC300C08F1 is square/MPa, while GFC300C08C1 would be round/MPa - the treatment function is otherwise the same.
