AirTAC GFC300-15 Combination Unit (GFC30015ALNW)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015ALNW) 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 5 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015ALNW)
The AirTAC GFC two-unit set combines a filter regulator and a lubricator in a matched two-piece package, so compressed air is filtered, regulated and then oiled through a single purchase. This configuration, the GFC30015ALNW, is the size 300 body with PT1/2 (1/2 inch) PT-threaded ports, a 5 um filter element (W grade) for finer particle and water removal than the standard 40 um element, an automatic drain on the filter bowl, and the low-pressure type regulator. No gauge is fitted (N code), and the polycarbonate bowls suit the working pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the G series, which spans sizes 200, 300, 400 and 600 with a choice of ports from 1/8 to 1 inch, thread options PT (standard), G (BSPP) or NPT, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and regulator variants including low-pressure type. Flow is published in the AirTAC catalogue as curves rather than a single rated figure, so we confirm datasheet figures on request before you order.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GFC30015ALNW)
| 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)). |
| L | Low-pressure 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. |
| W | Filtering grade 5 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: GFR300-15 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 (GFC30015ALNW) Is Used
CNC machining center air supply
Feeds cleaned, regulated and lubricated air to the tool-change cylinders and pneumatic clamps on a machining center, with the 5 um element protecting spool valves from fine contamination.
Automotive paint-shop line preparation
Installed at the drop of a paint-shop air line so atomizing air to spray applicators is filtered to 5 um, held at a stable low pressure, and carries a fine oil mist for actuator life.
Packaging line case-erector cylinders
Supplies the air cylinders that erect and seal corrugated cases on a packaging conveyor line, keeping moisture and particles out of the valves while the lubricator mists the cylinder seals.
Is the AirTAC GFC300-15 Combination Unit (GFC30015ALNW) the Right Set?
Size 300 with 1/2 inch PT ports is a mid-to-large step in the G series; step up to 400 or 600 for bigger ports and more flow, or down to 200 for compact lines. On the filter side, the 5 um W element here is the finer choice against the 40 um standard - pick 5 um where downstream valves and instruments need cleaner air. Drain choice matters: this unit has an automatic drain, which suits unattended installations; manual and differential-pressure drains are available on other codes. The regulator here is the low-pressure type, and this code carries no gauge; gauge variants with MPa, psi or bar scales can be selected on other codes. Thread is PT as standard, with G (BSPP) and NPT available as order options.
Because AirTAC publishes flow as performance curves and not as one rated number, ask us to confirm sizing against your application - flow, and any figure not covered above - before placing the 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 0.15 - 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 (GFC30015ALNW) FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so there is no one rated-flow number we can quote. Send us your application details and we will confirm the flow and sizing against the datasheet on request.
The N in the model code means no gauge is fitted; this two-unit set is ordered without one. Gauge variants across the GFC series do exist - an embedded square gauge is the standard option, with MPa, psi or bar scales available - so if you want a pressure readout, choose a code without the N or contact us and we will confirm the right part.
