Airtac GFC Combination Unit GFC300C08F1W
The AirTAC GFC Combination Unit GFC300C08F1W 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 GFC300C08F1W
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator plus a lubricator, so one model filters, regulates and lubricates compressed air. This GFC300C08F1W is size 300 with PT1/4 ports, fitted with the fine 5 um (W) filter element, a square embedded gauge on the MPa scale, and the standard differential-pressure drain on the bowl, which bleeds off collected water as flow conditions change.
This is a genuine AirTAC part. The GFC family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and in PT, G (BSPP) or NPT thread, with 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and optional external round gauges. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application.

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 GFC300C08F1W Is Used
Automated assembly cylinder supply
Feeds filtered, regulated and lubricated air to the cylinder and valve bank of an assembly station, with the 5 um element helping keep fine particulate out of directional control valves.
Carton-sealing packaging machine
Prepares air for the flap-fold and tape-head actuators on a case-sealing line: water drained from the bowl, pressure set at the gauge, and oil mist carried to the actuator seals.
Maintenance-shop air tool bench
A drop point for impact wrenches, ratchets and grinders in a plant maintenance bay, where the lubricator oils the tool motors and the regulator sets a safe working pressure.
Is the Airtac GFC Combination Unit GFC300C08F1W the Right Set?
Size 300 with 1/4 inch PT ports suits compact machine supply points; step up to size 400 or 600 for higher air demand, or down to 200 for small circuits. The 5 um (W) element is the right choice where finer particulate matters; the 40 um standard element suits general supply. This unit carries a square MPa gauge; an external round gauge on MPa, psi or bar scale is an option, and PT, G or NPT thread is chosen at order.
Because AirTAC publishes flow as performance curves and not as one rated number, we cannot quote a flow figure here. Send us your application and we will confirm sizing against the datasheet 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 GFC300C08F1W FAQ
AirTAC does not publish a single rated flow figure for the G series; flow is given as performance curves that vary with pressure and setting. That is why we do not quote a number here - contact us and we will confirm the curve and datasheet figures against your application before you order.
This model is built with the W option, so it filters to 5 um instead of the standard 40 um. Choose 5 um where downstream valves, cylinders or instruments are sensitive to finer particulate; 40 um is adequate for general machine supply. Regulation range with the differential-pressure drain fitted is 0.15-0.9 MPa (20-130 psi).
