AirTAC GFC300-15 Combination Unit (GFC30015AC1K)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015AC1K) 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 (GFC30015AC1K)
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator and a lubricator in one assembly, so a single connection removes water and particulate from the compressed air, holds downstream pressure steady, and adds an oil mist for 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 an MPa scale; the K suffix means a reverse (check) valve is fitted. 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, 300, 400 and 600 with ports from 1/8 to 1 inch, plus options for drain type, 5 um filtration, gauge scale and G (BSPP) or NPT threads. On this size 300 set the 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 (GFC30015AC1K) Is Used
CNC machining centre air supply
Feeds filtered, regulated and lubricated air to tool-changer cylinders and spindle clamps on a machining centre, while the fitted check valve holds downstream pressure if the shop supply dips.
Bottling line conveyor actuators
Prepares the air feeding pusher and stopper cylinders along a bottling conveyor: water and particles removed, pressure held steady, and an oil mist keeps cylinder seals in working condition.
Automotive assembly cell air tools
Supplies impact wrenches and pneumatic ratchets at an assembly cell with clean, regulated, oil-misted air, with the automatic drain clearing condensate from the filter bowl on its own.
Is the AirTAC GFC300-15 Combination Unit (GFC30015AC1K) the Right Set?
Size 300 with 1/2 inch ports suits lines with substantial air demand; step down to size 200 for lighter circuits or up to size 400/600 when you need larger ports and more flow. Drain: the automatic drain (A) ejects condensate without attention - choose manual (M) only if bowls are checked routinely, or the differential-pressure default for intermittent duty. Filtration is the standard 40 um element; specify W for 5 um where downstream equipment needs finer protection. The gauge here is the external round type on an MPa scale (C1); C2 gives psi instead. Thread is PT as the standard, with G (BSPP) and NPT available as catalogue options to order. Flow for this series is published as curves, not a single rating, so send us your pressure and 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 (GFC30015AC1K) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number here. Send us your operating pressure and air demand and we will confirm the datasheet figures for this two-unit set on request before you order.
It adds a reverse (check) valve to the regulator section, which holds pressure on the downstream side if the upstream supply is interrupted - useful where a sudden pressure loss would drop clamps or stop a cycle. The rest of the decode is unchanged: size 300, PT1/2, automatic drain, 40 um element and MPa round gauge.
