AirTAC GFC300-15 Combination Unit (GFC30015MN)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MN) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015MN)
The AirTAC GFC30015MN is a two-unit air preparation set: a filter-regulator plus a separate lubricator in the 300 size with PT1/2 ports. The filter bowl is drained manually, so condensate is removed by hand as part of your maintenance routine. Filtration is the standard 40 um element, which takes out water and particulate from the compressed air line, and the regulator downstream of the element gives an adjustment range of 0.05-0.9 MPa (7-130 psi) in this manual-drain configuration. The lubricator in the second unit meters oil mist into the regulated air for downstream cylinders, valves and air tools. Maximum working pressure is 1.0 MPa (145 psi), the PC (polycarbonate) bowl suits 300-size units, and operating temperature is -5 to 70 C (non-freezing). The N code means no gauge is fitted on this variant.
This is a genuine AirTAC part sold through an authorised distribution channel. The G series spans sizes 200, 300, 400 and 600 with a choice of drain type, 5 um (W) or 40 um filtration, gauge and scale options, and G (BSPP) or NPT thread variants as catalogue options. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet flow data for your application.

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 0.05 - 0.9 MPa (7 - 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 (GFC30015MN)
| 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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. |

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 (GFC30015MN) Is Used
CNC machining cell air supply
Feeds filtered, regulated and lubricated air to tool-changer cylinders and pneumatic clamps on a CNC machining centre. The 40 um element strips water and pipe scale before the regulator, and the manual drain suits a fixed daily maintenance walk.
Furniture finishing spray line
Conditions the air feeding spray guns and air-driven agitators in a wood-finishing booth: filtered and regulated at PT1/2, with the lubricator metering oil mist to keep gun trigger valves and air motors working smoothly.
Bottling line conveyor gating
Supplies the pneumatic stops, gates and pushers along a bottling conveyor. The regulator holds a steady set pressure for consistent cylinder action, and the lubricator extends the service life of the gating cylinders.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MN) the Right Set?
Step up or down through the G series sizes (200/300/400/600) to match your port and the flow your line needs; the 300 size with PT1/2 ports sits mid-range. Choose the drain to match your maintenance pattern: manual (this model, M) for hand draining, automatic (A) for continuous blowdown, or the default differential-pressure drain. This variant carries the standard 40 um element; order the W code if you need 5 um filtration. It ships as a code with no gauge fitted (N); gauge variants of the GFC series are available as separate codes. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options.
Because rated flow is published as curves and not as a single number, send us your flow and duty details and we will confirm sizing from the datasheet before you order.
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 0.05 - 0.9 MPa (7 - 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 (GFC30015MN) FAQ
Rated flow for the G series is published as curves, not as a single rated figure, so we do not quote one number here. Tell us your line pressure and demand and we will confirm the flow data for the GFC30015MN from the AirTAC datasheet on request.
M is a manual drain: the filter bowl is emptied by hand on a maintenance schedule. N means no pressure gauge is fitted; gauge versions of the GFC300 series exist as separate catalogue codes if you want a visual pressure reading. With the manual drain, the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
