AirTAC GFC400-15 Combination Unit (GFC40015F1W)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F1W) 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 (GFC40015F1W)
GFC40015F1W 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. In this size 400 unit the PT1/2 ports take a half-inch line, the W code fits the finer 5 um filtration element, and the polycarbonate filter bowl carries the standard differential-pressure drain that bleeds condensate as flow resumes. The regulator has 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. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range 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, 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 (GFC40015F1W) Is Used
CNC machining cells
Feeds tool-changer and spindle-clamp valves on a machining centre with 5 um filtered, regulated air, while the lubricator mists the clamp and ejector cylinders.
Paint booth spray equipment
Supplies finer 5 um air to refinish spray guns and booth actuators, with the regulator setting gun supply pressure and the lubricator serving downstream air cylinders.
Packaging carton sealers
Conditions the air driving carton-closing and taping heads on a packaging line, keeping contaminants out of seal cylinders and keeping sliding surfaces oiled.
Is the AirTAC GFC400-15 Combination Unit (GFC40015F1W) the Right Set?
Size 400 with PT1/2 ports is the mid-large step of the G series; step up to 600 for larger ports and more flow, or down to 300 when demand is lighter. This unit uses the differential-pressure drain; specify the A code for an automatic drain or M for a manual drain if your line idles frequently. The W code selects the 5 um element for finer protection of valves and instruments, versus the standard 40 um grade. The F1 square gauge reads MPa, with other scales available. Thread is PT as standard; G (BSPP) and NPT versions are catalogue options to order. AirTAC publishes flow 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 (GFC40015F1W) FAQ
AirTAC publishes flow for the G series as performance curves rather than one rated number, so we do not quote a single figure here. Send us your working pressure and air demand and we will confirm sizing from the datasheet on request.
The W in the code selects the optional 5 um element instead of the standard 40 um grade. Choose 5 um where downstream valves, cylinders or instruments need finer protection; 40 um suits general pre-filtration. Both grades work with the same bowls and drain arrangements.
