AirTAC GFC300-15 Combination Unit (GFC30015ALC1)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015ALC1) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC300-15 Combination Unit (GFC30015ALC1)
The GFC30015ALC1 is an AirTAC G-series two-unit air preparation set: a 300-size filter regulator plus a separate lubricator, giving filtration, regulation and oil-mist lubrication in two pieces. The L in the code marks the low-pressure regulator type, suited to circuits that must run at gentle set pressures. This unit is drilled for 1/2 inch ports on standard PT thread, has an automatic drain on the filter bowl, standard 40 um filtration and a round external gauge reading in MPa.
It is a genuine AirTAC part, rated for a maximum working pressure of 1.0 MPa (145 psi) and -5 to 70 C non-freezing operation, with polycarbonate bowls on the 300 size. The G series spans sizes 200 to 600 with a choice of drain types, 40 um or 5 um elements, gauge styles and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm flow and datasheet figures for your application 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 (GFC30015ALC1) Is Used
Spray booth gun supply
Steps plant air down to the gentle set pressure spray guns and air-assist circuits need in a paint booth, while the lubricator keeps the gun trigger and needle pack running smoothly.
Carton sealing machine
Feeds the flap-tuck and hold-down cylinders of a carton sealer running at low set pressure, with the MPa gauge letting line staff check the setting at a glance.
Pneumatic valve actuation
Prepares air for quarter-turn actuators on butterfly and ball valves across a process skid that runs at low regulated pressure, keeping the actuator seals lubricated season after season.
Is the AirTAC GFC300-15 Combination Unit (GFC30015ALC1) the Right Set?
The 1/2 inch PT port on this 300-size set fits lines whose air demand has moved beyond 1/4-inch and 3/8-inch units; drop to size 200 if consumption is small. The L code selects the low-pressure regulator type; because its adjustment span differs from the standard type, we confirm the exact range from the datasheet on request. Drain here is automatic, expelling condensate without operator attention. Filtration is the standard 40 um; order the W variant if 5 um is needed. The C1 code adds a round external gauge with an MPa scale, and square dials or psi/bar scales are also orderable. Flow is published as curves, not a single rating, so ask us to confirm sizing 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 (GFC30015ALC1) FAQ
Flow for the G series is published as curves, not a single rated figure, so we do not state a rated number. Tell us your line pressure and air consumption and we will confirm sizing against the AirTAC datasheet curve before you order.
L selects the low-pressure regulator type in the filter regulator, intended for circuits that run at gentle set pressures. Its adjustment span differs from the standard type, so we confirm the exact range from the datasheet on request.
