AirTAC GFC300-08 Combination Unit (GFC30008C1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008C1W) 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 (GFC30008C1W)
GFC30008C1W is an AirTAC G-series two-unit air-treatment set: a filter-regulator and a lubricator working as a pair on 1/4 in PT connections. The W code fits the finer 5 um filter element instead of the standard 40 um, so the regulator bowl sheds both water and finer particulate before the lubricator meters oil mist downstream. The drain is the default differential-pressure type, the regulator spans 0.15-0.9 MPa (20-130 psi), and the round external gauge reads on the MPa scale. Bowls are polycarbonate at this size, maximum inlet pressure is 1.0 MPa (145 psi), and the working range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series comes in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options that include manual or automatic drains, gauge scales, and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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: GFR300-08 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 (GFC30008C1W) Is Used
Paint-spray gun supply in a body shop
Conditioning the air feeding spray guns in an automotive refinishing booth, where the 5 um element keeps finer dirt out of the paint path and the lubricator oils the gun trigger valves.
Injection-moulding core-pull circuits
Supplying core-pull and ejector cylinders on injection-moulding machines, where finer filtration protects the mould valve package and the MPa gauge allows quick pressure checks.
Lab automation actuator supply
Feeding the gripper and lift actuators on laboratory automation benches, with regulated, finely filtered and lubricated air from a single 1/4 in set.
Is the AirTAC GFC300-08 Combination Unit (GFC30008C1W) the Right Set?
Match the size step (200/300/400/600) and port (1/8 in to 1 in) to your circuit - this 300 set is built around 1/4 in piping. Here you are choosing the 5 um element (W) over the standard 40 um, a step worth taking when downstream equipment is sensitive to finer dirt; the trade-off is a more frequent element check. The drain stays the default differential-pressure type, with automatic and manual codes available. The gauge is the external round type on the MPa scale; psi and bar scales exist. PT is the standard thread, with G (BSPP) and NPT as options.
AirTAC states flow as curves, not one rated number, so ask us to confirm sizing for your application before you order.
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 (GFC30008C1W) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not state a number here. Give us your application parameters and we will confirm the datasheet flow curve and the fit of this 1/4 in set on request.
The W code fits a 5 um filter element, so particulate removal is finer than the standard 40 um grade. Choose it for sensitive downstream equipment; if coarse protection is enough, the plain GFC30008C1 at 40 um is the base option.
