AirTAC GFC300-08 Combination Unit (GFC30008F3W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F3W) 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 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008F3W)
The AirTAC GFC series pairs a filter-regulator with a lubricator in one two-unit set, so a single assembly cleans the air, fixes the working pressure and supplies oil mist downstream. This 300-size model is ported PT1/4, carries the fine 5 um W filter element instead of the standard 40 um, drains its bowl on the differential-pressure principle, and has an embedded square pressure gauge scaled in bar.
This is a genuine AirTAC part. The G series covers 200 to 600 size and ports from 1/8in to 1in, with this two-unit set orderable with automatic, manual or differential-pressure drain, either filter grade, psi, bar or MPa gauges, and PT, G(BSPP) or NPT threads. Flow is published as curves, not a single rating, so we confirm 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.
Model Code: AirTAC GFC300-08 Combination Unit (GFC30008F3W)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 (GFC30008F3W) Is Used
Electronics pick-and-place cells
Fine 5 um filtration, set pressure and light oiling for the small cylinders and ejectors of a PCB pick-and-place or test bench fed at 1/4in.
Pneumatic screwdriver stations
A conditioned 1/4in supply for assembly-bench screwdriving spindles, keeping grit out of the clutch mechanisms while the lubricator mists the motor.
Analytical instrument enclosures
Prep air inside an instrument cabinet or pilot rig where fine particulate must be removed before it reaches reference-air components.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F3W) the Right Set?
Size by port and demand: this 300 unit gives a PT1/4 connection, with 200, 400 and 600 sizes stepping the port and flow capability up or down. The differential-pressure drain here sheds condensate while air is flowing; automatic and manual drains are orderable alternatives, and the drain type 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 5 um W element is the reason to pick this variant over the standard 40 um - use it when the downstream valves or tools are sensitive to fine particulate.
The gauge scale is bar (psi and MPa exist), PT is the standard thread with G and NPT as catalogue options, and no reverse valve is fitted. 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 (GFC30008F3W) FAQ
AirTAC publishes G-series flow as curves rather than a single rated number, so we do not state a figure here. Share your working pressure and air consumption and we will confirm the fit from the datasheet curves on request before you order.
The W selects the fine 5 um filter element in place of the standard 40 um element - everything else about the set is the same. If your application is general plant air, the non-W version with the 40 um element is the usual choice.
