AirTAC GFC300-15 Combination Unit (GFC30015MLN)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MLN) 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 (GFC30015MLN)
The AirTAC GFC series is a two-piece air preparation set: a filter regulator plus a separate lubricator, so one installation filters, regulates and lubricates the compressed air supply. This GFC30015MLN is the size 300 unit with PT1/2 ports (PT thread is the standard), a manual drain bowl, the L low-pressure regulator type, no gauge fitted (N), and the standard 40 um filter element. Maximum working pressure is 1.0 MPa (145 psi), the manual-drain regulator setting range is 0.05-0.9 MPa (7-130 psi), and operating temperature is -5 to 70 C (non-freezing). The size 300 bowls on both the filter regulator and the lubricator are PC (polycarbonate).
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600, with PT, G(BSPP) or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um (W) elements, gauge variants and optional brackets across the range. Flow is published as curves rather than a single rating, so ask us to confirm sizing and full datasheet figures for your application before ordering.

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 (GFC30015MLN)
| 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)). |
| 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 (GFC30015MLN) Is Used
Textile machine air jet and cylinder supply
Distributed along a weaving or spinning frame, the set cleans the mill air, holds the low working pressure the machine builder specifies, and oils the machine's air cylinders - with pressure read from the plant's own panel gauges.
Conveyor gate and stopper actuators
Feeding pop-up gates, stoppers and pushers along a packaging conveyor, the unit filters and regulates the supply and lubricates the actuators; where the panel already has a master gauge, this no-gauge variant keeps the set simple.
Maintenance shop air drop for air tools
At a workshop drop used for impact wrenches and air ratchets, the set removes water and 40 um dirt, sets a safe working pressure, and mists oil into the tool air line, with the manual drain emptied as part of routine checks.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MLN) the Right Set?
Start with size and port: 200 to 600 covers small point-of-use drops up to large machine headers, and stepping up a size gives a larger port and more flow capacity. This unit is size 300 with PT1/2 ports; G and NPT threads are catalogue options if your piping is BSPP or NPT. Drain type matters: this M code is the manual drain variant, which also widens the regulator setting range to 0.05-0.9 MPa (7-130 psi); automatic (A) and differential-pressure (default) drain variants are available. This is the L low-pressure type with the standard 40 um element - choose W for 5 um filtration. The N code means no gauge is fitted; if you need local pressure indication, gauge variants with square (MPa, psi or bar scales) or external round gauges exist in the same size. Bracket choices are also available.
Because AirTAC publishes flow only as curves, not a single rated figure, ask us to confirm sizing against your actual air demand 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 (GFC30015MLN) FAQ
AirTAC publishes flow for this series as performance curves rather than a single rated number, so there is no one figure we can honestly quote here. Send us your line pressure and required air consumption and we will confirm the correct size and the datasheet curve figures on request.
N means the regulator part is supplied without a gauge, which suits panels and machines that already have pressure indication elsewhere. If you want local reading, the same size is available with an embedded square gauge in MPa, psi or bar scales, or with an external round gauge. Everything else in the code is unchanged: PT1/2, manual drain, low-pressure type, 40 um element.
