Heavy-duty cooling.
Quiet where it matters.
From steel mills, foundries and paper plants to food processing lines, hospital rooftops and dense HVAC installations — one retrofit engineering platform. AFI SML smartfans™, HD heavy-duty fans and patented STEALTHFANS™ deliver the efficiency, resilience and low-noise performance each environment demands.
Rising energy costs meet the harshest atmospheres on Earth.
Demanding energy needs and their rising costs constitute a major challenge to the steel and paper industries. Designed to provide high performances by minimizing power consumption, our fans cool hundreds of critical and continuous processes worldwide. The HD series operates in very harsh environments and resists the corrosion and erosion phenomena typical of steelworks, foundries and pulp & paper plants — keeping primary cooling online and the production line moving.
Continuous-process steel, paper and food plants run cooling 8,760 hours a year. Every percent of fan efficiency directly cuts megawatt-hours and a six-figure power bill.
Sinter plants, blast furnaces and recovery boilers expose fans to high temperatures, abrasive particulate and aggressive chemistry. Materials and coatings have to match.
An unscheduled cooler shutdown stops the entire line. Robust hubs, corrosion-resistant airfoils and field-replaceable blades keep mills and plants producing.
A changing climate, a denser city, a quieter machine.
Food processing and HVAC industries are challenged by climate change, the increase of population and concentration in urban areas. Our fans are successfully installed and operating in hundreds of factory-assembled cooling devices, providing the highest levels of efficiency. Our patented, field-tested low-noise STEALTHFANS fan is the right answer to mitigate the effects of noise and vibration in very sensitive installations like hospitals, schools and residential communities.
Rising ambient temperatures and longer cooling seasons push factory-assembled chillers and rooftop units harder every year. Our fans hold their efficiency curve at peak summer duty.
Equipment now sits on hospital roofs, school courtyards and apartment blocks. Compact, lightweight fans retrofit into existing fan rings without structural reinforcement.
Patient wards, classrooms and residential balconies demand strict acoustic envelopes. STEALTHFANS deliver low sound power without trading away airflow or efficiency.
Three fan platforms for every industrial cooling duty.
From primary cooling towers and ACHE banks in corrosive, high-temperature service, to package chillers and rooftop units in noise-sensitive urban communities — each series answers a precise operating profile.
HD Series — Cooling towers, ACHE banks & process coolers
The HD Series is engineered for the brutal duty of steelworks and paper mills: large cooling towers, air-cooled heat exchangers and primary process coolers running in atmospheres loaded with iron oxides, sulphur compounds and pulping chemistry. Hot dip galvanized hub disc, FRP airfoils with stainless steel leading-edge protection and operation from −45 °C to +80 °C let the same fan serve a tropical mill or a Nordic plant.
- Built for corrosive & erosive atmospheres
- FRP airfoils · stainless steel leading-edge armor
- Hot dip galvanized hub · field-replaceable blades
SML Series — Auxiliary cooling, dry coolers, package chillers & rooftop units
Around the steel mill, the paper plant and the food processing line — and on hundreds of factory-assembled package chillers and rooftop air handlers — the SML smartfans™ series delivers the highest efficiency in its diameter class. Aluminum or FRP airfoils, adjustable pitch and a fast-assembly conical bushing make it the fan of choice for OEMs and operators alike.
- Auxiliary, utility & factory-assembled cooling
- Aluminum or UV-resistant FRP airfoils
- Adjustable pitch · fast OEM assembly
Hospitals, schools, communities — stealthfansTM answers.
The stealthfansTM series is the fruit of a two-year AFI research program and represents the most advanced product in the field of very low-noise axial fans for HVAC and food-industry cooling. It is the only series that combines low noise with high efficiency, low weight, reduced axial space requirement and a cost comparable to a regular fan — letting OEMs offer their factory-assembled equipment with a very low-noise option as standard, not premium.
Better than the average regular-noise fan — power consumption stays low even when operating in low-noise mode on rooftop chillers and HVAC units.
Lighter than a standard axial fan of equal duty, reducing structural load on hospital, school and residential rooftop installations.
Reduced axial footprint allows STEALTHFANS to be retrofitted into existing factory-assembled equipment with minimal modification.
Comparable in cost to a regular-noise fan — letting OEMs offer low-noise as the standard option, not a premium upgrade.
