Airtac GFC Combination Unit GFC300C08AC1W
The AirTAC GFC Combination Unit GFC300C08AC1W 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 GFC300C08AC1W
GFC300C08AC1W is a genuine AirTAC G-series two-unit combination: a GFR300 filter-regulator paired with a GL300 lubricator, so it filters water and particulate out of the air, regulates downstream pressure and adds oil mist for downstream tools in one 1/4 in (PT1/4) connection. This configuration has an automatic drain on the filter bowl, a 5 um (W) filter element instead of the 40 um standard, and a round external pressure gauge reading in MPa. Maximum inlet pressure is 1.0 MPa (145 psi) and, with the automatic drain, the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). It runs on compressed air only, from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFC two-unit family is available in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, 40 um standard or 5 um (W) filtration, automatic, manual or differential-pressure drains, round or square gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow figures for the G series are published as curves rather than a single rating, so ask us and we will confirm the datasheet for this exact model 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 GFC300C08AC1W Is Used
Packaging line pick-and-place supply
Conditioning the air feeding the vacuum and clamp cylinders on a carton-forming line: the 5 um element protects the valve stack, the regulator holds consistent cylinder force, and the lubricator keeps the actuator seals working shift after shift while the automatic drain clears condensate without stopping the line.
Pneumatic press and clamping fixtures
Supplying filtered, regulated and lubricated air to the clamping fixtures on a small pneumatic press, where the MPa gauge lets the setter set and verify clamping pressure directly and the automatic drain suits a fixture mounted where daily bowl draining is impractical.
Automated assembly cell air preparation
Serving as the single air-preparation point for a rotary indexing assembly cell: one 1/4 in PT connection upstream of the manifold feeds every cylinder and air tool with clean, regulated, oil-misted air, with the 5 um grade chosen to shield the fine-control valves in the cell.
Is the Airtac GFC Combination Unit GFC300C08AC1W the Right Set?
Match the size to the air demand and piping: this 300-size set connects at PT1/4 (1/4 in), while the GFC family steps from size 200 at 1/8 in up to size 600 at 1 in as flow requirement rises. This unit has an automatic drain, which suits unattended or hard-to-reach installations; manual-drain and differential-pressure-drain versions exist at the same size. The 5 um (W) element gives finer filtration than the 40 um standard, which matters for sensitive valves and cylinders. The gauge here is the round external type in MPa; square-gauge (F) versions and psi or bar scales are also in the family. The 300-size bowls are polycarbonate (PC), and the operating range is -5 to 70 C.
Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. AirTAC publishes flow for the G series as curves, not a single rated figure, so send us your working pressure and air demand and we will confirm sizing against the curve before you order.
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 GFC300C08AC1W FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your working pressure and air demand and we will confirm the flow curve and full datasheet for this exact model on request before you order.
W is the filter-grade code: this set carries the 5 um element instead of the 40 um standard. Choose 5 um when the downstream valves, cylinders or instruments are sensitive to fine particulate; choose the standard 40 um grade for general shop-air duty where finer filtration is not required.
