AirTAC GFC300-08 Combination Unit (GFC30008F1W)
The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008F1W) 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 (GFC30008F1W)
The AirTAC GFC series pairs a filter regulator with a lubricator as a two-unit set, so one line-up cleans and regulates compressed air and then feeds oil mist to downstream equipment. This GFC30008F1W is the 300 size with PT1/4 ports and the W filter grade: a 5 um element in place of the standard 40 um, for finer particle removal ahead of sensitive valves and actuators. The filter section uses a differential-pressure drain, and the regulator carries an embedded square gauge with an MPa scale, adjusting from 0.15 to 0.9 MPa (20-130 psi).
This is a genuine AirTAC part for compressed air, rated to 1.0 MPa (145 psi) working pressure and -5 to 70 C (non-freezing), with polycarbonate (PC) bowls at the 300 size. The series also offers 200/400/600 sizes, G and NPT threads, automatic and manual drains, and a reverse (check) valve option. Flow is published as curves rather than a single rated figure, so we 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 (GFC30008F1W) Is Used
Air motor agitator drives
Feeds vane air motors on mixing and agitating stations, where the 5 um element keeps fine particles out of the motor and the lubricator supplies the oil mist air motors need.
Pneumatic riveting and press tools
Conditions air for foot-operated riveters and small pneumatic presses at a bench, with set pressure read on the square MPa gauge and oil mist protecting the cylinder seals' moving parts.
Textile machine cylinder supply
Prepares air for the thread-tension and doffing cylinders on textile machinery, where the 5 um grade helps protect the machine's directional valves from particulate carryover.
Is the AirTAC GFC300-08 Combination Unit (GFC30008F1W) the Right Set?
Match the size to the flow demand: 200/300/400/600 covers 1/8 in. to 1 in. ports, and this 300 size with 1/4 in. PT ports suits compact machine drops. The W suffix selects the 5 um element instead of the standard 40 um - specify it where finer particle removal matters, and the plain suffix where standard filtration is enough. Drains are differential-pressure (this model), automatic or manual; gauge scales are 1 = MPa, 2 = psi, 3 = bar; threads can be ordered as PT (standard), G (BSPP) or NPT. 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 (GFC30008F1W) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Note that the finer 5 um element sits in the same 300-size body as the standard model. Send us your application and we will confirm the flow and datasheet figures on request before you order.
The standard grade is 40 um; the W suffix changes the element to 5 um for finer particle removal ahead of sensitive valves, air motors or actuators. Everything else - PT1/4 ports, differential-pressure drain, square MPa gauge and the lubricator - stays the same as the standard GFC30008F1 configuration.
