AirTAC GFC300-10 Combination Unit (GFC30010NK)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010NK) 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 PT3/8" ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-10 Combination Unit (GFC30010NK)
The GFC series is AirTAC's two-unit air preparation set: a filter regulator and a lubricator working as one pair, so a single order covers filtration, pressure regulation and oil-mist lubrication for the downstream circuit. This GFC30010NK is the 300 size with 3/8in PT ports, a 40 um standard filter element and a differential-pressure drain on the bowls, which are polycarbonate (PC) at this size. A reverse (check) valve is fitted, and the set is supplied without a gauge - square and round gauge variants exist in the same series. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, so the same two-unit function is available with larger or smaller ports, automatic or manual drains, a 5 um element (W code), G (BSPP) or NPT threads instead of the PT standard, and with or without gauges. AirTAC publishes flow as characteristic curves rather than a single rated figure, so ask us to confirm curve data and the full datasheet 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.
Model Code: AirTAC GFC300-10 Combination Unit (GFC30010NK)
| GFC300 | G-series two-unit set, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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)). |
| (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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GFR300-10 filter regulator and GL300-10 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 GFC300-10 Combination Unit (GFC30010NK) Is Used
CNC fixture clamping
Feeds the clamp and support cylinders on a machining-centre fixture with filtered, regulated and lubricated air, while the fitted check valve blocks reverse flow in the supply line.
Carton sealing heads
Prepares the air feeding tape-head and flap-folding cylinders on a case-sealing conveyor, keeping sealing pressure steady through each carton cycle.
Maintenance bay air tools
Supplies impact wrenches, die grinders and ratchets on a plant maintenance drop, adding oil mist so the tools stay lubricated in daily service.
Is the AirTAC GFC300-10 Combination Unit (GFC30010NK) the Right Set?
Choose the 300 size when your circuit calls for 3/8in PT ports; step down to 200 or up to 400/600 if the port size and the curve-based flow of those sizes match your demand better. Keep the differential-pressure drain for continuously running lines, or order the A (automatic) or M (manual) variants. The standard 40 um element suits general actuator protection; pick the W code for a 5 um element where finer filtration matters. This build has no gauge - variants with the embedded square gauge or an external round gauge in MPa, psi or bar scale are available, as are G (BSPP) and NPT thread options in place of PT. Flow is published as curves, not a single rating, so ask us to check the curve against your air demand before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR300-10 filter regulator on its own.
AirTAC GFC300-10 Combination Unit (GFC30010NK) FAQ
AirTAC does not publish a single rated flow figure for this set - flow is given as characteristic curves. Send us your line pressure and air demand and we will confirm the curve data and the full datasheet on request before you order.
Yes. The N in GFC30010NK simply means no gauge is fitted. The same 300 series is offered with an embedded square gauge or an external round gauge in MPa, psi or bar scale, so order the matching variant if you want a pressure readout at the unit.
