AirTAC GFC300-08 Combination Unit (GFC30008F3)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F3) 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 PT1/4" ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008F3)
The AirTAC GFC series combines a filter-regulator and a lubricator into one two-unit assembly: water and particulate are removed, working pressure is set, and oil mist is fed to downstream equipment. This 300-size model is ported PT1/4, uses the standard 40 um filter element for general plant air, drains its bowl on the differential-pressure principle, and carries an embedded square pressure gauge scaled in bar.
This is a genuine AirTAC part. The G series runs from 200 to 600 size with ports from 1/8in to 1in, and this two-unit set is orderable with automatic, manual or differential-pressure drain, 5 um or 40 um filtration, psi, bar or MPa gauge scales, and PT, G(BSPP) or NPT threads. Flow appears only as curves in the catalogue, so we confirm exact sizing and datasheet figures 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.

| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

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: GFR300-08 filter regulator and GL300-08 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 GFC300-08 Combination Unit (GFC30008F3) Is Used
Packaging line carton sealers
Clean, regulated, lubricated air for the cylinders and vacuum ejectors on a carton-forming and sealing conveyor, with the bowl catching line-air condensate.
Pneumatic press riveting station
Stable set pressure and oil mist for the air cylinders of a bench riveting or light stamping press fed from a 1/4in plant-air drop.
Trailer air-tool drop points
A wall-mounted prep point in a fleet workshop that conditions shop air before impact wrenches and tyre cages draw from it.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F3) the Right Set?
Match the port to the job: this 300 unit is PT1/4; move to 200, 400 or 600 when the flow you need calls for a smaller or larger port. The differential-pressure drain fitted here needs no operator attention during normal flow; the catalogue also offers automatic drains for standby draining and manual drains, and the drain choice sets the regulator range (differential and auto: 0.15-0.9 MPa / 20-130 psi; manual: 0.05-0.9 MPa / 7-130 psi). The 40 um element here is the standard grade for general-purpose air; choose the 5 um W element when feeding finer components.
The gauge reads bar (MPa and psi scales exist), PT is the standard thread with G and NPT as orderable options, and no reverse valve is fitted on this version. 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 (PT1/4" 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 GFR300-08 filter regulator on its own.
AirTAC GFC300-08 Combination Unit (GFC30008F3) FAQ
AirTAC publishes flow for the G series as curves rather than a single rated figure, so there is no one number to quote. Send us your line pressure and consumption and we will confirm the size against the datasheet curves on request.
The 40 um element fitted here is the standard grade for general plant air feeding cylinders, valves and air tools. If the same set will feed finer components such as precision valves or spray equipment, the identical unit is available with the 5 um W element - just order that variant.
