AirTAC GFC300-15 Combination Unit (GFC30015LN)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015LN) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015LN)
The GFC family combines a filter-regulator and a separate lubricator in one two-piece set, so a single assembly filters, regulates and lubricates compressed air. The GFC30015LN is the size 300 unit with 1/2 in PT ports, the standard 40 um filter element, a differential-pressure drain on the bowl (polycarbonate on this size) and the low-pressure (L) type regulator, ordered without a gauge (N).
This is a genuine AirTAC part, not a copy or substitute. The G series is offered in sizes 200, 300, 400 and 600, with automatic, manual or differential-pressure drains, 40 um or 5 um elements, round or square gauge choices, and a maximum working pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing). Flow and other datasheet figures are confirmed 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. 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 (GFC30015LN)
| 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". |
| (blank) | Drain: Differential-pressure 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. |
| (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. |
| (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 (GFC30015LN) Is Used
Conveyor diverting stations
Feeding pusher and stopper cylinders along a conveyor line from a 1/2 in PT branch, with filtration, regulation and lubrication handled by one two-unit set in the panel.
Dock leveller controls
Supplying the lifting and lip cylinders of a loading-dock leveller, where the low-pressure type regulator and a gaugeless panel layout keep the machine air circuit simple.
Maintenance shop tool drops
Conditioning air at a workshop hose station so impact wrenches and air ratchets receive clean, regulated and oiled air through a 1/2 in PT supply.
Is the AirTAC GFC300-15 Combination Unit (GFC30015LN) the Right Set?
The N suffix means no gauge is fitted, which suits panels where pressure is read elsewhere; add a gauge by choosing F or C with scale 1 (MPa), 2 (psi) or 3 (bar) in the code. This 300 unit gives 1/2 in PT ports; step up to 400 or 600 for larger demand. The 40 um element suits general actuation, and W selects 5 um. Drain is differential-pressure as coded, with automatic (A) or manual (M) selectable, and the L suffix selects the low-pressure type. Regulation with the differential-pressure drain covers 0.15-0.9 MPa (20-130 psi).
PT is the standard thread; G (BSPP) and NPT are catalogue options you can order by changing the trailing code letter. AirTAC publishes flow as curves rather than one rated number, so send us your flow demand and we will confirm sizing against 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 0.15 - 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 (GFC30015LN) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no number is stated here. Send your required flow and line pressure and we will confirm sizing from the datasheet on request before you order.
Only the gauge: LN is ordered with no gauge fitted (N), while LF1 includes the embedded square gauge with an MPa scale. Add F or C with a 1, 2 or 3 scale code if you want local pressure indication.
