AirTAC GFC300-10 Combination Unit (GFC30010N)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010N) 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 (GFC30010N)
The AirTAC GFC series pairs a filter-regulator with a lubricator in a two-unit set, giving filtered, regulated and oil-mist lubricated compressed air from one mounting. This 300-size configuration is ported PT3/8 with the default differential-pressure drain on the filter bowl, standard 40 um filtration, no gauge, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi).
It is a genuine AirTAC part for compressed air, rated to 1.0 MPa (145 psi) maximum working pressure and -5 to 70 C, with a PC (polycarbonate) bowl at this size. The G series spans sizes 200 to 600 with ports from 1/8 to 1 inch; flow is published as curves rather than a single rating, so we confirm the datasheet figures 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 (GFC30010N)
| 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. |
| (blank) | No reverse-flow valve (the default). |
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 (GFC30010N) Is Used
General plant air drops
A fit-and-forget conditioning point on a plant air header, where the differential-pressure drain handles condensate without operator attention.
Belt conveyor take-up air
Regulates and lubricates the air to tensioner and guide cylinders along a conveyor run fed from a PT3/8 branch.
Maintenance workshop outlets
Conditions supply air at workshop drops where technicians connect impact tools and blow guns that need regulated, lubricated air.
Is the AirTAC GFC300-10 Combination Unit (GFC30010N) the Right Set?
Size 300 is the PT3/8 step in the G range; move to 400 or 200 to match your line - flow is published as curves, not a single rating, so ask us to confirm sizing against the application before ordering. With the drain position blank, this unit carries the differential-pressure drain; automatic (A) and manual (M) drains are the other catalogue choices. Filtration is the standard 40 um; add W in the code for 5 um. The N specifies the set without a gauge, and no check valve is fitted. PT thread is standard, with G (BSPP) and NPT available as catalogue options.
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 (GFC30010N) FAQ
There is no single rated flow figure to quote: AirTAC publishes G-series flow as curves. Send us your application's flow and pressure requirements and we will confirm the numbers from the datasheet on request so you order the right size.
No - the N in the code specifies this two-unit set without a gauge. Gauges are a catalogue option on GFC sets, so if you want downstream pressure visible at the unit, ask us about the gauge-equipped variant of the same size and port.
