AirTAC GFC300-08 Combination Unit (GFC30008AC3W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008AC3W) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-08 Combination Unit (GFC30008AC3W)
This GFC two-unit set combines a filter regulator and a lubricator, so filtration, pressure regulation and oil-mist lubrication arrive as one matched order for compressed air. The GFC30008AC3W is the 300 size with PT1/4 ports, the fine 5 um filter element, an automatic drain on the bowl, and a round external gauge reading in bar. Use it where you want finer-than-standard air cleanliness plus self-draining condensate handling on a continuously supplied line.
It is a genuine AirTAC G-series part, made across the 200, 300, 400 and 600 sizes with choices of filter grade, drain type, gauge scale and PT, G or NPT thread. Maximum working pressure is 1.0 MPa (145 psi), the temperature range is -5 to 70 C, and with automatic drain the regulator covers 0.15 to 0.9 MPa (20 to 130 psi). Published flow is curves, not a single rating, so we confirm 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 (GFC30008AC3W)
| 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". |
| A | Drain: Automatic 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 (GFC30008AC3W) Is Used
Laboratory instrument air feed
Conditions the compressed air serving laboratory analysers and sample-handling pneumatics, where the 5 um element supports cleaner air than the standard grade and the bar gauge matches the instruments' readouts.
Laser cutting head assist-air panel
Mounted in the service panel of a laser cutting cell to filter, regulate and lubricate the pneumatics around the cutting head and clamping, with automatic drain keeping condensate off the consumables.
Truck-mounted equipment pneumatics
Supplies the gate, lift and clamp cylinders on truck-mounted handling equipment, combining fine filtration and lubrication in one unit with an auto drain suited to vehicles that cannot rely on manual checks.
Is the AirTAC GFC300-08 Combination Unit (GFC30008AC3W) the Right Set?
The 300 size with 1/4-inch PT ports fits most machine supply drops; select 400 or 600 for heavier air demand or 200 for compact enclosures. This code pairs the finer 5 um element (W) with the automatic drain - the low-attention combination; manual and differential-pressure drains remain available. The round gauge reads in bar, and MPa or psi scales plus G or NPT threads are catalogue alternatives. Remember that flow is given as curves rather than a rated figure, 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 (GFC30008AC3W) FAQ
AirTAC publishes flow for the G series as characteristic curves rather than a single rated value, so no one number is quoted here. Give us your working pressure and demand and we will confirm the datasheet flow figures for this set on request.
The W code selects the 5 um element, which removes finer particulate than the 40 um standard - useful for sensitive valves, jets and instruments. If general cylinder supply is all you need, the standard grade keeps element choice simple; both are orderable on the same GFC300 set.
