Airtac GFC Combination Unit GFC400C10N
The AirTAC Airtac GFC Combination Unit GFC400C10N 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 GFC400C10N
GFC400C10N is an AirTAC G-series two-unit air preparation set: a filter-regulator and a lubricator built together as one F+R+L package. It removes water and particulate from compressed air, regulates downstream pressure across a 0.15-0.9 MPa (20-130 psi) adjustment range, and meters oil mist to the air tools and cylinders it feeds. This code is ported PT 3/8 in., carries the standard 40 um filter element, uses the default differential-pressure drain, and is supplied without a pressure gauge (trailing N).
This is a genuine AirTAC part. The GFC family spans 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in., an optional 5 um element (W), automatic or manual drains, and G (BSPP) or NPT threads as catalogue choices; PT threading is the standard for this code. At size 400, the filter-regulator bowl and the lubricator oil bowl are both polycarbonate. Maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm datasheet figures 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: 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 GFC400C10N Is Used
CNC machining center pneumatics
Feeding the tool-changer, clamps and chip-door cylinders of a CNC machining center with filtered, regulated and lubricated air held at one fixed setting.
Carton case-erector line
Supplying the box-forming and flap-fold cylinders on a packaging case erector, with condensate knocked out before it reaches the directional valves.
Bottling line diverter gates
Running stopper and diverter gates on a bottling conveyor, with the lubricator servicing the gate cylinders through each shift.
Is the Airtac GFC Combination Unit GFC400C10N the Right Set?
Step up to the 400 size when the 300 port or flow path is too small for the line; port 10 gives a PT 3/8 in. connection. The differential-pressure drain fitted here needs no operator attention between bowl services; automatic (A) and manual (M) drains can be ordered instead, and note the regulator range becomes 0.05-0.9 MPa with a manual drain. Keep the 40 um element for general actuation circuits, or order the W version for 5 um filtration. As an N-coded set it comes without a gauge; the series also offers an embedded square gauge or an external round gauge in MPa, psi or bar scales. AirTAC publishes flow as curves, not one rated figure, so send us your 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 GFC400C10N FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so we do not quote a number the datasheet does not state. Send us your working pressure and flow demand and we will confirm sizing against the datasheet on request.
The trailing N in GFC400C10N means the set is supplied without a gauge. If you want one, the GFC series can be ordered with the embedded square gauge or an external round gauge, in MPa, psi or bar scales.
