AirTAC GFC400-10 Combination Unit (GFC40010AC1)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010AC1) 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 (GFC40010AC1)
The AirTAC GFC series pairs a filter regulator with a lubricator in a two-piece set covering filtration, pressure regulation and oil-mist lubrication. This GFC40010AC1 is the size 400 unit with 3/8 in PT ports, the standard 40 um filter element and an automatic drain that empties the filter bowl without daily attention. An external round pressure gauge with MPa scale is included, and the regulator adjusts outlet pressure across 0.15-0.9 MPa (20-130 psi). It runs on compressed air from -5 to 70 C (non-freezing) at up to 1.0 MPa (145 psi) inlet, with polycarbonate bowls on both sections.
This is a genuine AirTAC part. The G series runs from size 200 to 600 with ports from 1/8 in to 1 in, plus G (BSPP) and NPT thread variants, manual or differential drains, a 5 um element option, gauge choices and a check-valve option, so a matching set can be ordered for most lines. Flow is published as curves rather than a single rating; ask us to confirm the datasheet figures and sizing 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: 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 (GFC40010AC1) Is Used
Pick-and-place robotics
Point-of-use treatment for pick-and-place robot cells: the regulator sets cylinder and gripper pressure, the lubricator feeds the actuator air, and the round MPa gauge lets technicians verify the setting at a glance.
Assembly plant air drops
Fits assembly-station air drops where the automatic drain clears condensate from the bowl on lines that run through breaks and shift changes without anyone bleeding the bowl by hand.
Truck service bay
Feeds impact wrenches, air jacks and inflation stations in a commercial-vehicle service bay, with the 3/8 in PT ports matching typical shop drop hoses and the gauge showing regulated tool pressure.
Is the AirTAC GFC400-10 Combination Unit (GFC40010AC1) the Right Set?
Size 400 with 3/8 in PT ports suits medium plant-air and machine supply lines; move to size 300 for compact branches or size 600 where larger ports are needed. This version takes the automatic drain (A) for hands-off condensate removal, while the standard differential-pressure drain and the manual drain (M) remain order choices. The element is the standard 40 um grade; specify W for 5 um. The external round gauge reads in MPa; square gauges and psi or bar scales can be ordered. 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 (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 (GFC40010AC1) FAQ
There is no single rated flow figure: AirTAC publishes G-series performance as flow curves. Send us your working pressure and air consumption and we will confirm the correct size from the datasheet on request.
A specifies an automatic drain, which empties the filter bowl without manual attention. The alternatives are the standard differential-pressure drain or a manual drain (M) - note that manual-drain versions regulate across 0.05-0.9 MPa (7-130 psi), while this automatic-drain set regulates 0.15-0.9 MPa (20-130 psi).
