STEALTH Series
A patented low-noise fan that finally beats the trade-off — silence, efficiency and weight, all at once. The very low-noise reference from 6′ to 40′.
Engineered to your duty point.
Drop-in retrofit.
The STEALTHFANS series is the result of a two-year AFI research program and a patented technical solution. It is the most advanced very low-noise axial fan available for cooling and ventilation equipment — and the only low-noise series that simultaneously delivers high efficiency, low weight, reduced axial space requirement and a cost comparable to a regular-noise fan. For the first time, OEMs can offer their standard equipment with a true low-noise option without redesigning around it.
- Patented very-low-noise aerodynamic system
- Higher efficiency than an average regular-noise fan
- Lower weight than an average regular-noise fan
- Reduced axial space — drop-in retrofit friendly
Where the STEALTH Series goes to work.
When the world's largest cooling installations need to cut energy, hit airflow targets and run 24/7 — they specify the STEALTH Series.
The construction manifest.
Standard materials are always corrosion-resistant or actively protected. Where corrosion is unavoidable, every interface is engineered to keep it out.
- Hub disc
- Hot dip galvanized steel with epoxy-coated central hub boss
- Airfoil profile
- Aluminum alloy or UV-resistant, antistatic FRP
- Wet tower armour
- Maintenance-free stainless steel sheet on FRP leading edge
- Blade attachments
- Hot dip galvanized steel and aluminum alloy
- Coating (optional)
- Polyurethane on any of the above components
