AirTAC GFC300-15 Combination Unit (GFC30015MLC1)
The AirTAC AirTAC GFC300-15 Combination Unit (GFC30015MLC1) 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 (GFC30015MLC1)
The AirTAC GFC is a two-unit set pairing a filter regulator with a lubricator, delivering filtered, regulated and oil-mist lubricated air from one assembly. This 300-size unit has a PT1/2 port, manual drain, the standard 40 um filter element, and the L code marks it as the low-pressure regulator type, intended for applications where the regulated pressure sits at the lower end of the scale. An external round pressure gauge with MPa scale is fitted.
This is a genuine AirTAC part. The GFC series is available in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and with drain, filtration, gauge and thread options to match. Maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. Because flow is published only as curves, we confirm flow, the exact adjustment range for the low-pressure type, 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 (GFC30015MLC1) Is Used
Laboratory air distribution
Conditioning the low-pressure air feeding bench-top lab apparatus and pneumatic actuators on an analytical instrument bench, with the round MPa gauge giving a clear external pressure readout.
Low-pressure blow-off station
Filtering, regulating and lubricating the air supply to a gentle blow-off and air-knife station on a production line where parts must be dried without high set pressures.
Textile machine air circuits
Treating the air that drives low-pressure cylinders and thread-guiding jets on textile machinery, where the lubricator oils the actuators and the 40 um element handles general plant air.
Is the AirTAC GFC300-15 Combination Unit (GFC30015MLC1) the Right Set?
Pick the L (low-pressure) regulator type when your process holds regulated pressure near the bottom of the scale - the exact adjustment range for this variant is confirmed on request. The 300 size with a 1/2 in PT port covers medium-duty drops; resize up or down to match the line. Manual drain suits staffed areas; automatic or differential-pressure drain codes serve unattended points. Filtration is the 40 um standard element - add W for 5 um if finer air is needed. The external round gauge reads in MPa; psi and bar scales and the embedded square gauge are alternatives. Thread is PT as standard with G (BSPP) and T (NPT) orderable.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 0.05 - 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 (GFC30015MLC1) FAQ
AirTAC publishes flow for this set as performance curves rather than a single rated figure, so we do not quote one number. Share your line pressure and air demand and we will confirm the sizing and figures from the datasheet on request.
The L in the code selects the low-pressure regulator type, intended for applications regulating at the lower end of the pressure scale; we confirm its exact adjustment range on request. Everything else is the standard 300-size build: 1/2 in PT port, manual drain, 40 um element, external round MPa gauge.
