AirTAC GFC300-15 Combination Unit (GFC30015AN)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015AN) 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 (GFC30015AN)
GFC30015AN is a genuine AirTAC G-series two-unit set: a filter-regulator and a lubricator supplied as two pieces that mount together, so the compressed air is filtered, regulated and then lubricated in one pass. This size 300 configuration has PT1/2 ports as standard, an automatic drain on the filter bowl, the standard 40 um filter element and no gauge fitted. The bowls are polycarbonate at this size, the set carries compressed air at up to 1.0 MPa (145 psi), and it operates between -5 and 70 C (non-freezing).
As an AirTAC part it belongs to the G series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and this automatic-drain version adjusts from 0.15 to 0.9 MPa (20-130 psi). Because flow for this series is published as performance curves rather than a single rating, ask us and we will confirm the datasheet figures for your application.

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.
Model Code: AirTAC GFC300-15 Combination Unit (GFC30015AN)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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 (GFC30015AN) Is Used
CNC machining-center clamp circuits
Feeds filtered, regulated and lubricated air to pallet- and workpiece-clamping cylinders on a machining center, where the lubricator keeps seal and bore wear down over long production runs.
Bottling-line stopper and gate cylinders
Conditions the air supply to conveyor gating and bottle-stopper cylinders on a filling line, with the regulator holding a stable set-point as line speed varies.
Carton-sealing packaging machines
Supplies conditioned air to the press cylinders and flap folders of a carton taping machine, combining water removal, pressure control and oil mist in one wall-mounted set.
Is the AirTAC GFC300-15 Combination Unit (GFC30015AN) the Right Set?
Size 300 with 1/2 inch ports suits medium-flow circuits; step to 400 or 600 for larger demand or down to 200 for compact lines, matching the port to your existing pipework. The automatic drain here expels condensate from the filter bowl without manual attention; a manual-drain or differential-pressure version can be ordered instead if preferred. This code carries the standard 40 um element - specify the W suffix for the 5 um grade if downstream equipment needs finer air. No gauge is fitted (N); an embedded square gauge or external round gauge with MPa, psi or bar scale can be added when ordering. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options, and bracket arrangements follow the family standard. Flow is published as curves, not a single rating, so send us your demand 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 (GFC30015AN) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number on this page. Send us your required flow (l/min, m3/h or SCFM) and working pressure and we will confirm from the datasheet whether size 300 at 1/2 inch is correctly sized for your circuit.
The automatic drain (code A) expels collected condensate from the filter bowl on its own, which suits unmanned or high-humidity installations. A manual drain needs periodic operator attention, and the default differential-pressure drain responds to the pressure differential across the element. All three are catalogue choices on this family - tell us your duty cycle and we will help you pick.
