AirTAC GFC400-10 Combination Unit (GFC40010AC3)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010AC3) 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 PT3/8" ports, a 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-10 Combination Unit (GFC40010AC3)
The AirTAC GFC two-unit set pairs a filter regulator with a lubricator in one matched order, covering filtration, pressure regulation and oil-mist lubrication on a compressed-air line. This GFC40010AC3 is the size 400 frame with a 3/8 in PT port, a 40 um standard filter element and an automatic drain. The regulator section adjusts between 0.15 and 0.9 MPa (20-130 psi), and the trailing 3 in the gauge code selects an external round gauge reading in bar. Maximum working pressure is 1.0 MPa (145 psi); operating range is -5 to 70 C.
This is a genuine AirTAC part. The G-series spans sizes 200 to 600 with ports from 1/8 to 1 in, with a choice of drain type, 40 um or 5 um filtration, gauge style and scale, and PT (standard), G or NPT threads. At this size the filter-section bowl is polycarbonate. Flow is published as curves rather than a single rating, so ask us to confirm datasheet and sizing 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: GFR400-10 filter regulator and GL400-10 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 GFC400-10 Combination Unit (GFC40010AC3) Is Used
CNC machining centre
Conditions the supply to tool-changer cylinders, chuck actuators and air-blast nozzles on a machining centre, where the standard 40 um element and steady regulated pressure keep the valve stack working cleanly.
Carton erector and sealer line
Feeds the clamp, fold and flap-tuck cylinders on a packaging carton line, with the automatic drain removing condensate between shifts without operator attention.
Tyre-service workshop
Supplies regulated, lubricated air to impact wrenches, bead breakers and inflation stations in a vehicle workshop, protecting the tools from water and debris in the shop air main.
Is the AirTAC GFC400-10 Combination Unit (GFC40010AC3) the Right Set?
Size 400 with a 3/8 in PT port is the mid-range step in the G-series; move to 600 for larger demand or to 300 or 200 for smaller circuits. Since flow is published as curves rather than a single rating, ask us to check the curve against your air demand before ordering. This code uses the standard 40 um element; a 5 um version is available if your valves need finer filtration. The automatic drain handles condensate unattended, while manual and differential-pressure drains are catalogue alternatives. The round gauge here reads in bar; MPa and psi scales and the square gauge style are also available, and G or NPT threads can be ordered instead of the standard PT.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GFR400-10 filter regulator on its own.
AirTAC GFC400-10 Combination Unit (GFC40010AC3) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number here. Send us your operating pressure and expected air consumption and we will confirm the sizing from the datasheet on request.
The final digit of the gauge code sets the scale: 1 selects MPa, 2 psi and 3 bar. This code carries a round external gauge on a bar scale; MPa and psi versions are catalogue options you can order under their matching codes.
