AirTAC GFC300-15 Combination Unit (GFC30015LC1)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015LC1) 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 (GFC30015LC1)
The AirTAC GFC30015LC1 is a two-unit compressed-air treatment set: a filter regulator paired with a separate lubricator, providing filtration, pressure regulation and oil-mist lubrication in one supply. The L suffix marks the low-pressure regulator type, intended where only a reduced set pressure is needed, and the C1 suffix specifies the external round pressure gauge scaled in MPa. This size 300 configuration has a PT1/2 in. port, standard 40 um filter element and differential-pressure drain; maximum working pressure is 1.0 MPa (145 psi). The exact adjustment range of the low-pressure type differs from the standard unit, so confirm it on request.
This is a genuine AirTAC part from the G-series, which runs in sizes 200, 300, 400 and 600 with 1/8 to 1 in. ports, G (BSPP) or NPT thread options, a choice of drains, both filter grades and standard or low-pressure regulator types. Flow is published as curves, not a single rating, so ask us to confirm sizing and datasheet figures 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.

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 (GFC30015LC1) Is Used
Low-pressure actuator bank
Running a bank of light-duty clamp or ejector cylinders that work at reduced pressure: the low-pressure regulator holds the gentle set point, the 40 um filter keeps the valves clean and the lubricator feeds the actuators.
Sorting gate air supply
Supplying diverters, gates and pushers on a sorting conveyor where delicate products need low regulated pressure, plus clean filtered air and oil mist to keep the small cylinders cycling smoothly.
Textile machine air
Conditioning supply air to textile or converting machinery with low-pressure jets and tensioning cylinders: filtration removes water and fibre-loaded particulate while the regulator and lubricator serve the actuation circuit.
Is the AirTAC GFC300-15 Combination Unit (GFC30015LC1) the Right Set?
Specify this code when the downstream equipment only needs a low set pressure - the L type regulator is the defining choice, and its adjustment range should be confirmed against your application before ordering. Size 300 with a PT1/2 in. port is the mid step of the G-series; move to size 200 for smaller ports or 400 and 600 for more flow. The differential-pressure drain empties the bowl automatically at high differential; manual (M) and automatic (A) are options. The round external gauge reads in MPa, with psi or bar scales and the embedded square gauge available. PT is standard thread, G (BSPP) and NPT are order options.
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against the datasheet 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 (GFC30015LC1) FAQ
AirTAC publishes flow for the G-series as characteristic curves, so there is no single rated figure to quote. Send us your working pressure, set pressure and air demand and we will confirm sizing against the datasheet on request before you order.
L marks the low-pressure regulator type, chosen where downstream equipment operates at a reduced set pressure rather than full line pressure. Its adjustment range differs from the standard type, so confirm the range with us for your application. The C1 suffix means the external round gauge with an MPa scale.
