Airtac GFC Combination Unit GFC400C15F1K
The AirTAC Airtac GFC Combination Unit GFC400C15F1K 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 GFC400C15F1K
GFC400C15F1K is an AirTAC G-series two-unit air treatment set: a filter-regulator and a lubricator supplied together, covering filtration, regulation and oil-mist lubrication of compressed air under one part number. This size 400 configuration is made for 1/2 inch PT ports, carries the standard 40 um element, drains by differential pressure, regulates from 0.15 to 0.9 MPa (20-130 psi), reads on the embedded square MPa gauge and is fitted with a reverse (check) valve, marked by the K at the end of the code.
It is a genuine AirTAC part rated to 1.0 MPa (145 psi) maximum working pressure, operating from -5 to 70 C, with polycarbonate bowls as standard at the 400 size. The GFC family also comes in 200, 300 and 600 sizes with 5 um filtration, automatic or manual drains, other gauge scales and G (BSPP) or NPT threads as orderable options. Flow is published as curves, not a single rating, 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 GFC400C15F1K Is Used
Robotic weld cell services
Filtered, regulated and lubricated air for clamp and gripper actuation around a robotic weld cell, with the K-coded reverse valve blocking reverse flow through the set.
Trailer assembly line
Conditioned air to the pneumatic torque tools and clamping fixtures along a trailer assembly line, where the regulator holds a steady setting for repeatable fastening.
Pneumatic valve test station
A regulated, lubricated supply for cycling valves and actuators on a workshop test bench, with the square gauge giving the technician a direct pressure readout.
Is the Airtac GFC Combination Unit GFC400C15F1K the Right Set?
Size 400 with a 1/2 inch PT port suits mid-to-large supply lines; step down to 200 or 300 for compact branches or up to 600 for a main header. This version adds the K-code reverse (check) valve, which blocks reverse flow through the set; the same set without it is GFC400C15F1. Drain is differential-pressure by default, with automatic (A) and manual (M) as alternatives, and the standard filter grade is 40 um - specify W for 5 um if you need finer filtration. Gauge scale (MPa, psi or bar) and G or NPT threads instead of PT are all orderable choices.
Because flow data for this series is published as curves rather than one rated number, ask us to check your flow and pressure conditions against the datasheet 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 GFC400C15F1K FAQ
Flow for the GFC series is published as capacity curves, not as a single rated figure, so we do not quote one number. Share your required flow and working pressure and we will confirm the correct size against the datasheet on request.
K marks that a reverse (check) valve is fitted in the set, blocking reverse flow through the unit. The identical set without the valve carries the code GFC400C15F1, so choose the K version only where your circuit needs that protection.
