AirTAC GFC300-10 Combination Unit (GFC30010C1K)
The AirTAC AirTAC GFC300-10 Combination Unit (GFC30010C1K) 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 (GFC30010C1K)
The AirTAC GFC series is a two-unit air treatment set: a filter regulator plus a separate lubricator, combining filtration, regulation and oil-mist lubrication. This GFC300-10C1K is the 300 size with PT3/8 ports, a differential-pressure drain, standard 40 um filtration, the round external MPa gauge, and the K option fitting a reverse/check valve in the regulator section.
This is a genuine AirTAC part for compressed air only. The GFC family spans 200, 300, 400 and 600 sizes with drain, filtration-grade, gauge and thread options; PT, G and NPT threads are catalogue choices. Flow is published as curves rather than a single rating, so we confirm datasheet figures and sizing 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 (GFC30010C1K)
| 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). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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 (GFC30010C1K) Is Used
Robotic gripper air supply
A two-unit set feeding gripper and tool-changer circuits on a robot cell, with the fitted check valve helping hold the regulated circuit against upstream supply dips.
Trailer brake test rigs
Filtering, regulating and lubricating air on a workshop rig servicing trailer air systems, where the check valve prevents backflow toward the supply side.
Bottling line diverters
Conditioning air to diverter and stopper cylinders on a bottling conveyor, keeping the actuation circuit clean, lubricated and protected from reverse flow.
Is the AirTAC GFC300-10 Combination Unit (GFC30010C1K) the Right Set?
Choose size (200/300/400/600) to match your port and flow needs - the 300 with 3/8 ports covers mid-range circuits. This variant carries the K suffix, meaning a reverse/check valve is fitted in the regulator; order the non-K code if you do not want it. Drain is differential-pressure here (automatic A or manual M are orderable), filtration is the standard 40 um (W gives 5 um), and the C1 suffix specifies the round external gauge with MPa scale. Thread is PT standard, with G and NPT as order options.
Because flow is published only as curves, ask us to confirm this unit's sizing against your application 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 (GFC30010C1K) FAQ
AirTAC publishes flow for this series as curves, not as a single rated number, so quoting one figure would be guesswork. Send us your line pressure and consumption and we will confirm the correct size from the datasheet before you order.
K means a reverse/check valve is fitted in the regulator section, allowing flow in one direction only through the unit. The rest of the decode is unchanged: 300 size, PT3/8 ports, differential-pressure drain, 40 um filtration, round external gauge with MPa scale, plus the lubricator that makes GFC a two-unit set.
