AirTAC GFC400-10 Combination Unit (GFC40010AF1K)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010AF1K) 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 (GFC40010AF1K)
The AirTAC GFC two-unit set pairs a filter regulator with a lubricator, covering filtration, pressure regulation and oil-mist lubrication in one matched package on a compressed-air line. This GFC40010AF1K 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 square gauge in the code reads on an MPa scale. The K suffix fits a reverse (check) valve, which keeps downstream pressure from bleeding back if the supply line drops or is isolated. 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, and the catalogue offers drain type, 40 um or 5 um filtration, gauge style and scale, thread (PT standard, G and NPT to order) and the K check-valve option. 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 (GFC40010AF1K) Is Used
Electronics pick-and-place cell
Feeds the grippers and Z-axis cylinders of a pick-and-place module on an electronics line; the check valve holds the gripper circuit if the shop air main dips, protecting parts in transit.
Blow-moulding clamp circuit
Conditions the supply to the clamp and pinch cylinders on a blow-moulding machine, where the check valve helps the clamp side hold pressure through upstream pressure fluctuations.
Pneumatic press with hold stage
Supplies a small pneumatic press that uses a dwell or hold stage in its cycle; the regulator sets the working force and the check valve keeps the hold circuit from decaying if supply pressure falls.
Is the AirTAC GFC400-10 Combination Unit (GFC40010AF1K) the Right Set?
Read the code as a build sheet: size 400 with a 3/8 in PT port sits mid-range in the G-series, so move to 600 or down to 300 or 200 as your air demand dictates; flow is published as curves, not a single rating, so ask us to confirm the curve against your application before ordering. This version adds the K check valve, the right choice when a circuit must hold its set pressure through a supply dip or isolation. The standard 40 um element suits general protection; specify W for a 5 um element. The automatic drain keeps maintenance hands-off, and the square MPa gauge is fitted; round gauges, psi and bar scales, and G or NPT threads are catalogue alternatives.
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 (GFC40010AF1K) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number. Share your working pressure and expected air consumption and we will confirm the sizing from the datasheet on request.
It indicates that a reverse (check) valve is fitted. The valve allows normal forward flow but blocks reverse flow, so the downstream circuit holds its pressure if the upstream supply drops or the line is shut off. Units without the K suffix do not include this valve.
