AirTAC GFC400-15 Combination Unit (GFC40015F1K)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F1K) 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 PT1/2" ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015F1K)
GFC40015F1K is an AirTAC G-series two-unit air treatment set: a filter regulator and a lubricator paired as one 2-piece combination. This size 400 unit has 1/2 in PT ports, a 40 um filter element and a differential-pressure drain on the filter bowl. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) and the embedded square gauge reads in MPa. A fitted reverse (check) valve holds downstream pressure when the upstream supply is shut off. Bowls on the 400 size are PC (polycarbonate); maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. The medium is compressed air only.
This is a genuine AirTAC part. The G series runs from size 200 to 600 with ports from 1/8 to 1 in, plus catalogue options for drain type (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge style and scale, and G (BSPP) or NPT threads. Flow for the series is published as curves rather than a single rating, so we confirm the datasheet figures for your application 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: GFR400-15 filter regulator and GL400-15 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 GFC400-15 Combination Unit (GFC40015F1K) Is Used
Warehouse dock levellers
Runs the air cylinders on dock leveller platforms; the check valve holds the platform position if the shop air supply drops during a loading cycle.
Welding cell clamping air
Feeds the fixture clamps and tool-changer cylinders in a robotic welding cell, with the MPa square gauge for setpoint adjustment at the cell.
Process skid valve actuators
Supplies pilot air to the pneumatic valve actuators on a process skid; the check valve keeps the pilot line pressurised through upstream supply switching.
Is the AirTAC GFC400-15 Combination Unit (GFC40015F1K) the Right Set?
Size 400 with PT1/2 ports sits in the upper half of the G range (sizes 200 to 600, ports 1/8 to 1 in); move up or down a size to match your piping and demand. The K code fits a reverse (check) valve, which holds downstream pressure on supply loss - order without K if you do not need it. Drain type on the filter bowl is differential-pressure here; automatic (A) and manual (M) versions exist. Filtration is 40 um standard, with 5 um available under the W code. Gauge: this unit is coded F1, the embedded square gauge in MPa; C codes select the external round gauge in MPa, psi or bar. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. Flow is published 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 (PT1/2" 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 GFR400-15 filter regulator on its own.
AirTAC GFC400-15 Combination Unit (GFC40015F1K) FAQ
AirTAC publishes G-series flow as curves rather than a single rated figure, so no number is stated here. Give us your line pressure and demand and we will confirm the flow and datasheet figures for this model on request before you order.
GFC combines the filter regulator and lubricator as a two-piece set; GC is the three-piece filter, regulator and lubricator. Both filter, regulate and lubricate, so the choice is mainly mounting layout and whether you want the three functions as separate serviceable pieces.
