AirTAC GFC400-15 Combination Unit (GFC40015MF1W)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015MF1W) 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 manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015MF1W)
The AirTAC GFC40015MF1W is a genuine two-unit air-treatment set: a filter regulator plus a separate lubricator, filtering, regulating and oil-mist lubricating in one assembly, with the W suffix specifying the finer 5 um filter element instead of the 40 um standard. This 400-size unit is configured for PT1/2" ports, with a manual drain on the polycarbonate filter bowl and an embedded square pressure gauge reading in MPa. Maximum inlet pressure is 1.0 MPa (145 psi); with the manual-drain set the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi); working temperature is -5 to 70 C (non-freezing); compressed air is the only medium.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes, covering ports from 1/8" to 1", with differential-pressure (default), automatic or manual drains, 40 um or 5 um elements, and G (BSPP) or NPT threads as catalogue options. Flow is published as curves rather than a single rated figure, so we confirm flow and other datasheet values 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 0.05 - 0.9 MPa (7 - 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 (GFC40015MF1W) Is Used
Paint spray booth gun stations
Supplies spray guns in a paint booth with finely filtered (5 um), regulated and lubricated air at PT1/2", so the finish is not spoiled by coarse particulate riding in the shop-air line.
Analytical instrument air supply
Feeds lab analyzers and pneumatic sample-handling hardware that are sensitive to particulate, delivering 5 um-filtered air at a stable set pressure with oil mist for the moving actuator parts.
Pneumatic valve manifold feed
Conditions the 1/2" supply to a directional-valve manifold on process machinery, with the 5 um element defending spool clearances and the lubricator misting the downstream cylinders.
Is the AirTAC GFC400-15 Combination Unit (GFC40015MF1W) the Right Set?
Pick the 200/300/400/600 size by port and air demand; this 400 unit at PT1/2" serves mid-to-high demand circuits. The W suffix selects the 5 um element for applications where the 40 um standard is too coarse - otherwise drop the W. Drain is manual here; automatic (A) and differential-pressure (default) versions cover unattended draining. The embedded square gauge reads MPa, external round gauges with MPa/psi/bar scales are available, G (BSPP) and NPT threads are order options, and the bracket is included unless the J suffix is specified. Flow appears in the catalogue only as curves, not one rating, so send us your flow demand and we will confirm the right size against the datasheet before you order.
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 0.05 - 0.9 MPa (7 - 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 (GFC40015MF1W) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Share your application flow and port requirements and we will confirm the sizing against the datasheet on request.
The 40 um element is the G-series standard and suits general plant air. The W suffix specifies a 5 um element for equipment with tighter cleanliness needs, such as spray finishing, instrumentation and fine valve manifolds. Function, ports, drain and gauge stay the same - only the filtration grade changes.
