Airtac GFC Combination Unit GFC300C15MN
The AirTAC GFC Combination Unit GFC300C15MN 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC300C15MN
The GFC300C15MN is an AirTAC G-series two-unit set: a filter-regulator plus a lubricator, providing filtration, pressure regulation and oil-mist lubrication in one ordered package. This configuration is size 300 with PT1/2 ports, drains the filter bowl manually, uses the standard 40 um filter element, and is ordered without a pressure gauge (code N). At size 300 the bowls are polycarbonate. Maximum working pressure is 1.0 MPa (145 psi); with the manual-drain arrangement the regulator adjusts from 0.05-0.9 MPa (7-130 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied for the US market. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options include G (BSPP) or NPT threads, automatic or differential-pressure drains, 40 um or 5 um elements, square or round gauges with MPa, psi or bar scales, and a reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application.

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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C1 filter regulator and GL300-C1 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 GFC Combination Unit GFC300C15MN Is Used
Packaging machinery actuator banks
Conditions air for carton-former, sealer and case-packer cylinders on a 1/2 in header, with one manual-drain set serving the whole machine frame.
Textile loom air circuits
Feeds doffing and tying cylinders on weaving machines where lubricated, regulated air keeps mechanical actions consistent across the shed.
Truck maintenance pit drops
Serves tyre cages, impact guns and inflation stations at fleet workshops, giving mechanics a regulated, lubricated supply at each 1/2 in drop.
Is the Airtac GFC Combination Unit GFC300C15MN the Right Set?
Size 300 with PT1/2 ports sits mid-range in the G series; move to 200 or 400 if your circuit needs less or more flow, since larger sizes carry larger ports and more flow. Manual drain suits points of use that are drained by hand; automatic and differential-pressure drain versions are available for unattended bowls. The standard 40 um element is fitted here, with a 5 um option if finer filtration is needed. This set is ordered without a gauge; square (embedded) or round gauges with MPa, psi or bar scales can be added. PT is the standard thread, with G (BSPP) and NPT as catalogue options. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC300C15MN FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so no number is quoted on this page. Share your line pressure and consumption and we will confirm the sizing figures from the datasheet on request.
The trailing N in the code orders the set without a gauge. Gauge options remain available for the GFC family: an embedded square gauge, or an external round gauge, with MPa (scale 1), psi (scale 2) or bar (scale 3) scales - just order the corresponding code variant.
