Airtac GFC Combination Unit GFC300C15MC1
The AirTAC GFC Combination Unit GFC300C15MC1 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 GFC300C15MC1
The GFC two-unit set pairs a filter-regulator with a lubricator in one order: the front unit removes water and particulate from the compressed air and holds downstream pressure steady, while the lubricator adds a fine oil mist for tools and cylinders. This 300-size configuration has PT1/2 (1/2 in) ports, a manual drain on the bowl, the standard 40 um filter element and an external round pressure gauge scaled in MPa. Maximum working pressure is 1.0 MPa (145 psi) and the set operates from -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, which spans 200, 300, 400 and 600 sizes with a choice of ports, threads (PT as standard, G and NPT as catalogue options), drain types and 40 um or 5 um filter grades. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet details 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. 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 GFC300C15MC1 Is Used
Bottling-line capping heads
Feeds clean, regulated and lubricated air to the pneumatic capping cylinders on a bottling line, with the manual drain bled at shift start-up and end.
CNC fixture clamping circuits
Supplies pressure-stabilised, oil-misted air to workholding clamps on a machining centre, keeping clamp force consistent part after part.
Conveyor diverter actuators
Conditions the air feeding diverter and stopper cylinders along a packaging conveyor, protecting seals from water and dirt in the supply line.
Is the Airtac GFC Combination Unit GFC300C15MC1 the Right Set?
In the G series, stepping from 300 up to 400 or 600 buys a larger port and more flow, while 200 steps down. The port code here decodes to 15 = 1/2 in, and the thread is PT as standard, with G (BSPP) and NPT available to order. Drain choices are differential-pressure (the default), automatic (A) and manual (M, this configuration) - a manual drain needs periodic bleeding, which suits dry, attended installations. Filter grade is 40 um standard or 5 um with the W suffix, and the gauge can be the external round type or an embedded square gauge, scaled in MPa, psi or bar. Because flow is published as curves, not a single rating, ask us to confirm sizing against the 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 GFC300C15MC1 FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure, port size and flow demand and we will confirm the sizing against the datasheet curves before you order.
The M in this code sets a manual drain: condensate is released by opening the drain when needed. If the unit sits unattended or the air is wet, order the A suffix for an automatic drain, or leave the suffix off for the differential-pressure default drain.
