The AirTAC Airtac GFC Combination Unit GFC400C10F1WK 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).
GFC400C10F1WK 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 W code selects the 5 um filter element, and the trailing K means a reverse/check valve is fitted. It is ported PT3/8 (3/8 in PT thread, the standard), uses the default 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, the standard 40 um grade, 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.
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.

A wall-mounted preparation point for the maintenance shop, feeding impact tools, test hoses and clamp fixtures with finely filtered, regulated, lubricated air.
Conditioning supply air to the grippers and clamps of a robotic palletiser, with the 5 um element protecting the pilot valves that meter each grip cycle.
Driving pneumatic panels and sliding-door actuators on an automated production module, where the check-valve build is specified on the air preparation unit.
The 400 size with a 3/8 in port is the mid-range G-series step; size up to 600 or a larger port for heavy demand, or down to 300 for light circuits, matching the port to real air use. This build combines the 5 um W element with the K reverse/check valve; omit K for the plain W set or specify the standard 40 um grade for general actuation. The differential-pressure drain regulates 0.15-0.9 MPa (20-130 psi), while A (automatic) or M (manual, 0.05-0.9 MPa / 7-130 psi) drains are orderable.
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
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 publishes G-series flow as curves rather than a single rated figure, so no one number is quoted here. Tell 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.
The trailing K codes that a reverse/check valve is fitted, on top of the W-code 5 um filter element. If you do not need the valve, GFC400C10F1W is the identical set without it; the rest of the code - 400 size, 3/8 in PT port, differential-pressure drain and square MPa gauge - decodes the same.
