Airtac GFC Combination Unit GFC300C08AF1
The AirTAC GFC Combination Unit GFC300C08AF1 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 GFC300C08AF1
GFC300C08AF1 is a genuine AirTAC G-series two-unit combination: a GFR300 filter-regulator paired with a GL300 lubricator, so it filters water and particulate from the air, regulates downstream pressure and supplies oil mist from one 1/4 in (PT1/4) connection. This configuration has an automatic drain on the filter bowl, the standard 40 um filter element, and the square 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 GFC300C08AF1 Is Used
Modular conveyor gating stations
Conditioning the supply to the stopper and gating cylinders at each station of a modular conveyor system, where the standard 40 um grade handles general shop air and the automatic drain keeps condensate off the manifold without operator attention.
Trailer and dock leveller controls
Supplying filtered, regulated and lubricated air to the controls of dock levellers and trailer restraint systems at a loading bay, where the square MPa gauge gives a clear pressure readout and the automatic drain copes with a location that is not checked daily.
General machine air take-off
Serving as the air-preparation take-off on a production machine that runs cylinders and air jets, combining filtration, regulation and lubrication behind one 1/4 in PT connection so the machine builder fits one unit instead of three.
Is the Airtac GFC Combination Unit GFC300C08AF1 the Right Set?
Size the set by air demand and port: this 300-size unit connects at PT1/4 (1/4 in), and the GFC family steps from size 200 at 1/8 in to size 600 at 1 in. This model uses the standard 40 um element, the right choice for general machine-air duty; the W option gives 5 um for finer protection. The F gauge code here means the square gauge with MPa scale; round-gauge (C) versions and psi or bar scales are also available. The automatic drain suits unattended installation, with manual and differential-pressure drain versions at the same size. The 300-size bowls are polycarbonate (PC), and the set operates from -5 to 70 C.
Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. AirTAC publishes G-series flow as curves, not a single rated figure, so share your 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 GFC300C08AF1 FAQ
AirTAC publishes flow for the G series as curves rather than a single rated figure, so we do not quote a rated flow. Tell us your working pressure and the air demand of the machine, and we will confirm the flow curve and datasheet for GFC300C08AF1 on request, and advise whether the 300 size or a neighbouring size is the better fit.
F is the square-gauge code and 1 is the MPa scale, so this set carries the square gauge reading in MPa. Alternatives in the family are the round external gauge (C codes) and psi or bar scales (scale codes 2 and 3). Pick the gauge style and scale that match the other instruments on your panel.
