AirTAC GFC300-15 Combination Unit (GFC30015NWK)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015NWK) 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 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015NWK)
GFC30015NWK is a two-unit air preparation set from the AirTAC G series: a filter regulator and a lubricator working together, so the downstream circuit gets filtered, regulated and oil-mist lubricated air from one assembly. It has PT1/2 ports, a differential-pressure drain on the filter bowl, a finer 5 um filter element and a fitted reverse/check valve; the regulator setting range is 0.15-0.9 MPa (20-130 psi). Maximum working pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the 300 size uses polycarbonate bowls. The set is ordered without a pressure gauge.
This is a genuine AirTAC part. G-series two-unit sets are available in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", PT as the standard thread and G (BSPP) or NPT as catalogue options, plus a choice of drain types, 40 um or 5 um elements, gauge arrangements and the check-valve option. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.
Model Code: AirTAC GFC300-15 Combination Unit (GFC30015NWK)
| 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". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

| 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. |
| W | Filtering grade 5 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 (GFC30015NWK) Is Used
Machining-cell fixture clamping
Regulated, lubricated air for the clamp cylinders on a fixture plate in a machining cell, with the check valve helping to hold the downstream circuit when supply pressure dips.
Loading-dock leveller controls
Air preparation for the lift and lip cylinders of a loading-dock leveller, where conditioned air keeps the directional valves working reliably in a dusty yard environment.
Textile spinning frame threading
Conditioned air for the yarn-threading jets and doffing cylinders on a spinning frame line, with the 5 um element guarding the small jet orifices against scale and particles.
Is the AirTAC GFC300-15 Combination Unit (GFC30015NWK) the Right Set?
Step up or down one G-series size when the port or air demand changes; the 300 size with PT1/2 suits lines fed at 1/2". This code pairs the differential-pressure drain with the 5 um element and adds the reverse/check valve (K); automatic or manual drains are available instead, and the standard 40 um element can be chosen where finer filtration is not needed.
Flow is published as curves, not a single rating, so send us your operating pressure and air demand and we will confirm the correct size against the datasheet before you order. PT is the standard thread; G (BSPP) and NPT are order options.
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 (GFC30015NWK) FAQ
Flow for the G series is published as performance curves, not a single rated figure, so we do not state one number here. Give us your operating pressure and air demand and we will confirm the sizing from the datasheet on request.
It means a reverse/check valve is fitted to the set. The rest of the code reads as GFC30015NW: 1/2" PT ports, 5 um element, differential-pressure drain and no gauge. If you need the valve's behaviour in your specific circuit confirmed, ask us and we will check the datasheet.
