AirTAC GFC300-15 Combination Unit (GFC30015AC3K)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015AC3K) 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 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015AC3K)
The AirTAC GFC combines a filter-regulator body with a separate lubricator in one two-unit set, covering filtration, pressure regulation and oil-mist lubrication together. This GFC30015AC3K is the 300 size with 1/2 inch PT ports, an automatic drain, the standard 40 um filter element, a round gauge scaled in bar, and the K option: a reverse (check) valve fitted, so downstream pressure is held if the upstream supply drops. With automatic drain, the regulator adjusts 0.15-0.9 MPa (20-130 psi) and maximum working pressure is 1.0 MPa (145 psi). The 300-size bowl is polycarbonate.
This is a genuine AirTAC part from the G series, which runs from size 200 to 600 with ports from 1/8 inch to 1 inch in PT, G (BSPP) or NPT. Flow is published only as curves with no single rated figure, so we confirm flow and datasheet details 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 (GFC30015AC3K)
| 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". |
| A | Drain: Automatic 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. |

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 (GFC30015AC3K) Is Used
Clamp circuits with pressure hold
Air preparation for clamping or gripper circuits where the fitted reverse valve helps hold downstream pressure if the main supply is cut, protecting the workpiece during a cycle.
Automated fixture panels
A machine-mounted air panel on automated test or assembly fixtures, combining filtration, regulation, lubrication and a check valve in one 1/2 inch PT supply point.
Machine tool pneumatics
Supplying pneumatic functions on machine tools such as tool-clamp and chip-clearing cylinders, with the automatic drain handling condensate during long production runs.
Is the AirTAC GFC300-15 Combination Unit (GFC30015AC3K) the Right Set?
Choose the size step (200/300/400/600) to match the pipe and air demand - here 300 at PT1/2. Drain: this model is automatic; manual and differential-pressure drains are the other catalogue options. Filter grade: 40 um standard, 5 um with the W variant. Gauge: external round, bar scale here; square-gauge scales are also offered. Thread: PT is the standard, with G (BSPP) and NPT as order options. The K suffix adds the reverse (check) valve - pick it when the circuit must hold pressure if supply is interrupted.
Flow is published as curves, not a single rating, so ask us to confirm sizing for your application before ordering.
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 (GFC30015AC3K) FAQ
We do not quote a single rated flow because AirTAC publishes G-series flow as curves rather than one number. Send us your demand and we will confirm the curve data and full datasheet figures for this 300-size, 1/2 inch PT set on request.
K fits a reverse (check) valve, so air does not flow back upstream - useful where downstream pressure should be held during a supply interruption. The rest of the decode is identical: automatic drain, 40 um element, round bar gauge, standard regulator on 1/2 inch PT ports.
