AirTAC GFC400-15 Combination Unit (GFC40015F1WK)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F1WK) 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 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015F1WK)
GFC40015F1WK is an AirTAC G-series two-unit air-treatment set for compressed air: a filter regulator and a lubricator combined as one 2-piece assembly, with a reverse (check) valve fitted. This size 400 unit has PT1/2 ports, the finer 5 um filtration element, and a polycarbonate filter bowl with the standard differential-pressure drain. The regulator carries an embedded square gauge reading in MPa and adjusts between 0.15 and 0.9 MPa (20-130 psi); the lubricator feeds an oil mist to downstream equipment. The K-code check valve helps hold downstream settings against backflow. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied by a US distributor. The G series spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 5 um or 40 um filtration, gauge scales, check-valve option, and thread options with PT as the standard (G and NPT are catalogue options to order). Flow is published as curves rather than one rated number, so we confirm sizing and 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: GFR400-15 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 (GFC40015F1WK) Is Used
Clamp-and-hold welding fixtures
Regulates and lubricates clamp cylinders on a welding fixture line, with the check valve helping hold clamp pressure if the plant air supply dips.
Pick-and-place gripper circuits
Conditions the half-inch supply feeding gripper and rotary-actuator manifolds on a robotic handling cell, with 5 um air protecting pilot valves.
Assembly press actuation
Serves pneumatic press and clamping circuits on a small-parts assembly line, keeping air clean, pressure set, and sliding surfaces lubricated.
Is the AirTAC GFC400-15 Combination Unit (GFC40015F1WK) the Right Set?
Size 400 with PT1/2 ports suits heavier half-inch circuits; move to 600 for more flow or to 300 for lighter demand. The differential-pressure drain is standard here, with automatic (A) or manual (M) drain codes available for lines that idle. The W code fits the 5 um element versus the standard 40 um grade, and the F1 square gauge reads MPa. The K suffix adds the reverse (check) valve, useful where backflow could upset a set pressure. Thread is PT as standard; G (BSPP) and NPT versions are catalogue options to order. Because AirTAC publishes flow as curves and not as a single rating, 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 (GFC40015F1WK) FAQ
AirTAC publishes flow for the G series as curves rather than one rated number, so there is no single figure to quote. Tell us your line pressure and consumption and we will confirm the sizing from the datasheet on request before you order.
K specifies that a reverse (check) valve is fitted in the set. It allows flow in the normal direction but helps prevent backflow, which is useful where a lost supply must not drain a charged downstream circuit. The same set without K is ordered as GFC40015F1W.
