Airtac GFC Combination Unit GFC400C15F1
The AirTAC Airtac GFC Combination Unit GFC400C15F1 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 GFC400C15F1
GFC400C15F1 is an AirTAC G-series two-unit air treatment set: a filter-regulator and a lubricator supplied together, so one part number covers filtration, pressure regulation and oil-mist lubrication of compressed air. This size 400 configuration is made for 1/2 inch PT ports, carries the standard 40 um filter element, drains by differential pressure, regulates from 0.15 to 0.9 MPa (20-130 psi) and comes with the embedded square gauge scaled in MPa.
It is a genuine AirTAC part with a 1.0 MPa (145 psi) maximum working pressure, a -5 to 70 C operating range and polycarbonate bowls as standard at the 400 size. AirTAC also builds the GFC family in 200, 300, 400 and 600 sizes, with 5 um filtration, automatic or manual drains, alternative gauge scales and G (BSPP) or NPT threads as orderable options. Flow is published as curves rather than one rated figure, so we confirm datasheet numbers 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. 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: GFR400-C1 filter regulator and GL400-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 GFC400C15F1 Is Used
CNC machining center supply
Filtered, regulated and lubricated air for the tool changer and clamping cylinders on a CNC machining center, with the MPa gauge letting setters verify line pressure at the machine.
Packaging line actuation
Clean, regulated air to carton-forming and sealing cylinders on a bottling or food packaging line, with the lubricator metering oil mist to keep the cylinders running through long shifts.
Sortation conveyor diverters
Regulated air for diverter, pusher and stopper cylinders on a distribution-center sortation conveyor, where a stable setting keeps divert timing consistent from lane to lane.
Is the Airtac GFC Combination Unit GFC400C15F1 the Right Set?
Start from the port and the air demand: size 400 with a 1/2 inch PT port is the mid-large step of the G-series, and moving to 200, 300 or 600 changes both the connection and the flow path, so match the size to your line rather than to the pipe alone. The drain here is differential-pressure, which responds to the pressure drop across the element; automatic (A) and manual (M) drains are the other codes. The 40 um element is the standard grade - choose W for 5 um where downstream valves need finer protection. The embedded square gauge reads in MPa; psi and bar scales and an external round gauge are options, and G (BSPP) or NPT threads can be ordered in place of the PT standard.
Flow for this family is published as curves, not as a single rating, so send us your flow and pressure conditions and we will confirm sizing against the datasheet before you order.
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 GFR400-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC400C15F1 FAQ
AirTAC publishes flow for the GFC series as capacity curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your required flow and working pressure and we will confirm the sizing against the datasheet on request.
F1 decodes as the embedded square pressure gauge with an MPa scale. psi (2) and bar (3) scales are available, and an external round gauge can be specified instead - tell us which scale your operators read and we will match the code.
