Airtac GFC Combination Unit GFC400C10F1K
The AirTAC Airtac GFC Combination Unit GFC400C10F1K 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 GFC400C10F1K
GFC400C10F1K is a genuine AirTAC G-series two-unit air preparation set - a 400-size filter-regulator and a 400-size lubricator on one assembly - that removes water and particulate, regulates downstream pressure and meters a fine oil mist to air tools and actuators. The trailing K means a reverse/check valve is fitted. This configuration is ported PT3/8 (3/8 in PT thread, the standard), keeps the default 40 um filter element and differential-pressure drain, and includes the embedded square gauge scaled in MPa.
Maximum inlet pressure is 1.0 MPa (145 psi), working temperature is -5 to 70 C non-freezing, and the 400-size bowls are polycarbonate (PC). With the differential-pressure drain the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Other G-series choices include sizes 200 to 600, ports from 1/8 to 1 in, automatic or manual drains, 5 um (W) filtration, G (BSPP) or NPT threads, and psi or bar gauge scales. Flow is published as curves, so we confirm datasheet figures 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 GFC400C10F1K Is Used
Robotic weld-cell grippers
Conditioning actuation air for gripper cylinders and clamps around a robotic welding cell, where steady regulated pressure keeps part positioning consistent.
Sortation diverters
Supplying pusher and diverter cylinders on a warehouse sortation conveyor, with filtered, lubricated air protecting the valves that cycle all day.
Stamping press feeders
Feeding the pneumatic feeder and clamp circuits of a metal stamping press, where the check-valve build is specified on the air preparation drop.
Is the Airtac GFC Combination Unit GFC400C10F1K the Right Set?
The 400 size with a 3/8 in port covers mid-range plant air demand; move to 600 or a bigger port for heavier circuits, or to 300 for light ones, matching the port to real air use. This differential-pressure drain version regulates 0.15-0.9 MPa (20-130 psi); the A code automates draining at low or intermittent flow, and M (manual) suits scheduled draining with the wider 0.05-0.9 MPa (7-130 psi) span. If you want the check-valve build, this K version carries it; drop the K to order the plain set.
The standard element here is 40 um; add W for 5 um where pilot valves and instrumentation sit downstream. The square gauge reads MPa, with psi and bar scales available, and PT is the standard thread with G (BSPP) and NPT as orderable options. AirTAC publishes flow only as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFC400C10F1K FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no one number is quoted here. Send us your line pressure and air demand and we will confirm the datasheet figures and check the 400 size and 3/8 in port against your application on request.
It codes that a reverse/check valve is fitted to this set. The same unit without the K (GFC400C10F1) is the standard build. Everything else in the code decodes identically: 400 size, 3/8 in PT port, 40 um element, differential-pressure drain and the embedded square MPa gauge.
