AirTAC GFC300-10 Combination Unit (GFC30010F3K)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010F3K) 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 (GFC30010F3K)
GFC30010F3K is AirTAC's G-series two-unit air preparation set for compressed air: a filter-regulator plus a separately mounted lubricator, so one supply connection removes water and particulate, holds a set downstream pressure and adds oil mist for the cylinders and tools that follow. This build carries the standard 40 um element, the differential-pressure drain, an embedded square gauge scaled in bar, and a reverse (check) valve fitted on the regulator. Ports are PT3/8 in the 300 size.
It is a genuine AirTAC part. The G-series runs from size 200 to 600, with PT, G (BSPP) or NPT threads, 40 um or 5 um filtration, differential-pressure, automatic or manual drains, MPa, psi or bar gauge scales, and an optional check valve, so the same function is available with a larger or smaller port. Flow is published as curves rather than a single rating; ask us and we will confirm sizing and 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 (GFC30010F3K)
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

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 (GFC30010F3K) Is Used
Pneumatic clamping on machining fixtures
Feeds and protects clamp cylinders on a CNC fixture: filtered, regulated and lubricated air to the clamps, with the fitted check valve helping hold the clamped circuit if the main supply dips mid-cycle.
Divert cylinders on a carton packaging line
Mounted at the drop feeding the pusher and diverter cylinders on a carton conveyor, so the actuation air stays dry, held at set pressure and oiled for long cylinder life.
Assembly bench air drop for hand tools
Installed at a plant air drop serving impact drivers and ratchets on an assembly bench: the filter-regulator cleans and steadies the supply while the lubricator mists oil into the tool air.
Is the AirTAC GFC300-10 Combination Unit (GFC30010F3K) the Right Set?
Start from port and flow: the 300 size with PT3/8 ports sits mid-range in the G-series; step to 200 for compact lines or to 400/600 where the header uses larger ports. This code fixes the standard 40 um element, the differential-pressure drain (automatic and manual drains are separate codes), the bar-scale square gauge and the fitted check valve; psi or MPa gauge scales and a build without the check valve are orderable. The thread is PT as the standard; G (BSPP) and NPT are catalogue options to order. The set runs on compressed air only, -5 to 70 C, non-freezing.
Then the honest routing: AirTAC publishes flow for this family as curves across pressure, not as one rated figure, so ask us to check the curve for the GFC30010F3K against your demand and pressure 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 (GFC30010F3K) FAQ
AirTAC publishes G-series flow as curves across working pressure, not as one rated number, so we do not quote a single figure. Tell us your line pressure and air demand and we will confirm sizing and the datasheet figures on request.
It marks a reverse (check) valve fitted on the regulator section, which helps hold downstream pressure if the upstream supply drops. The same set without the K is the standard build; drain type, filter grade and gauge scale are all separate orderable choices.
