Airtac GFC Combination Unit GFC300C08MF1W
The AirTAC GFC Combination Unit GFC300C08MF1W 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 GFC300C08MF1W
GFC300C08MF1W is an AirTAC GFC two-unit air-preparation set: a GFR300 filter regulator paired with a GL300 lubricator. The 300 size takes PT1/4 ports (PT is the standard thread; G and NPT are orderable options). This configuration has a manual-drain bowl, a 5 um (W) filter element and a square pressure gauge reading in MPa, so one two-piece assembly filters, regulates and lubricates the compressed-air line. Maximum inlet pressure is 1.0 MPa (145 psi); on this manual-drain version the regulator adjusts from 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing, and both bowls are polycarbonate at the 300 size.
This is a genuine AirTAC part supplied by us as a distributor. The GFC family spans 200, 300, 400 and 600 sizes with 1/8 inch to 1 inch ports, plus drain, filter-grade, gauge, thread and check-valve options. Flow for the 300 size is published as curves rather than a single rating, so ask us to confirm sizing or send the datasheet before you order.

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 GFC300C08MF1W Is Used
CNC machining centre air feed
Feeds filtered, regulated air to tool-changer and clamping cylinders on a machining centre, with the lubricator misting the actuator seals and the 5 um element guarding precision valves.
Packaging line carton sealer
Supplies the carton-sealing and case-erecting cylinders on a packaging conveyor, holding a set working pressure while the manual drain lets operators purge the bowl at shift checks.
Assembly bench pneumatic tools
Conditions the bench air drop feeding impact drivers and nutrunners at an assembly station, with the lubricator delivering oil mist to keep tool motors running smoothly.
Is the Airtac GFC Combination Unit GFC300C08MF1W the Right Set?
Choose the two-unit GFC set when you want the filter regulator and lubricator as separate, serviceable pieces instead of one body. Size by port and demand: this 300 version is PT1/4; step to 400 or 600 for larger ports and flow, or down to 200 for compact lines. Drain choice: manual (this code, drain by hand during checks), automatic (drains continuously) or the differential-pressure default. Filter grade: 5 um (W, this code) for finer protection or the 40 um standard. Gauge: this version has a square MPa gauge; psi or bar scales and round gauges are orderable. Thread: PT standard, G (BSPP) or NPT on request. A trailing K adds a reverse/check valve. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering.
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 GFC300C08MF1W FAQ
AirTAC publishes 300-size performance as flow curves rather than one rated figure, so we do not quote a single number here. Tell us your application and we will confirm the sizing from the datasheet on request.
W selects the finer 5 um filter element instead of the standard 40 um, useful ahead of sensitive valves. F1 fits the square pressure gauge with an MPa scale; other scales and gauge styles are orderable, and the manual drain means the bowl is emptied by hand.
