AirTAC GFC300-15 Combination Unit (GFC30015AC2)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015AC2) 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 PT1/2" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015AC2)
The AirTAC GFC series is a two-unit air preparation set pairing a filter-regulator with a lubricator, so one installation filters water and particles from the compressed air, regulates downstream pressure and supplies an oil mist to tools and cylinders. This GFC30015 configuration is size 300 with PT1/2 ports, an automatic drain on the filter bowl, the standard 40 um filter element, and an external round pressure gauge on a psi scale (C2) - convenient where the panel is read in imperial units. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum working pressure is 1.0 MPa (145 psi), and the temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G-series spans sizes 200 to 600 with ports from 1/8 to 1 inch, and options for drain type, 5 um filtration, gauge scale (MPa, psi or bar) and G (BSPP) or NPT threads alongside the PT standard. Size 300 bowls are PC (polycarbonate). Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet numbers 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: GFR300-15 filter regulator and GL300-15 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 GFC300-15 Combination Unit (GFC30015AC2) Is Used
Bottling plant filler actuators
Conditions the air feeding filler-head lift cylinders and gating actuators on a bottling line, with the psi-scaled gauge letting operators set and check pressures against imperial-rated machine documentation.
Furniture factory nailers and staplers
Supplies nail and staple guns at a furniture production bench with filtered, regulated, oil-misted air, while the automatic drain keeps condensate out of the distribution line during long shifts.
Process skid control valves
Prepares instrument-quality actuation air for pneumatically operated control valves on a process skid: 40 um filtration, steady regulated pressure, and lubrication for recurring valve strokes.
Is the AirTAC GFC300-15 Combination Unit (GFC30015AC2) the Right Set?
Size 300 with 1/2 inch ports suits lines with solid air demand; step to size 200 for lighter circuits or 400/600 for more flow. Drain: automatic (A) empties the bowl unattended, manual (M) suits regular inspections, and the differential-pressure default fits intermittent duty. Filtration is the standard 40 um element; add W for 5 um if finer protection is needed. The C2 suffix selects the external round gauge on a psi scale - pick C1 for MPa or C3 for bar if your panel reads those. Thread is PT as standard, with G (BSPP) and NPT available as order options. Because G-series flow is published as curves and not a single rating, send us your demand figures and we will confirm sizing against the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GFR300-15 filter regulator on its own.
AirTAC GFC300-15 Combination Unit (GFC30015AC2) FAQ
Flow for this series is published as curves rather than a single rated figure, so the honest route is to match the curve to your consumption. Send us your working pressure and required airflow and we will confirm the datasheet figures for this two-unit set on request before you order.
The GFC bundles the filter-regulator and lubricator into two bodies, saving panel space and connection points, while the GC keeps all three functions as separate units. Both deliver filter, regulate and lubricate; if you need the modules individually replaceable or spaced apart, pick the GC, otherwise the GFC does the same job more compactly.
