Fan Systems

Do More With Less.

Less energy. Fewer fans. Lower harmonics.

Infinitum Fan Systems deliver the airflow you need with fewer motors, less energy, and ultra-low harmonics that free up electrical capacity for revenue-generating IT load.

The Challenge

Most fan systems look great on paper

until they're installed

Traditional fan systems face three critical challenges that impact your bottom line and operational efficiency.

Efficiency drops at partial load

Most systems spend 80% of their operating time at 30-70% capacity. That's exactly where traditional motors lose efficiency and cost you the most.

Harmonics spike

Poor power quality forces you to oversize transformers and generators "just in case." Passive filters underperform. Active filters are expensive and take up valuable space.

Electrical infrastructure gets oversized

More motors mean more amps. More amps mean thicker wires, bigger breakers, and less capacity for revenue-generating IT loads.

Common questions about fan systems

Can I retrofit Infinitum systems into existing air handlers?

Yes. Our modular design is specifically engineered for easy retrofits. The systems are lighter than traditional fan arrays, making transportation and installation simpler. We work with your team to ensure proper sizing and integration with existing building automation systems.

What makes Infinitum’s harmonics performance different?

Every Infinitum motor includes an integrated Active Front-End (AFE) that actively mitigates harmonics at the source. This achieves THDi < 1.4% and 98% power factor across the entire load curve, eliminating the need for external filters and reducing transformer/generator oversizing requirements. Standard EC motors typically require passive filters or centralized active filtering, which adds cost and complexity.

How does the modular design impact maintenance?

Individual motor modules can be replaced in under 30 minutes without shutting down the entire system. The PCB stator design is 10x more reliable than traditional iron-core motors, and components are designed for reuse and remanufacturing, extending the system lifespan to 100+ years.

Are Infinitum fan systems compatible with building automation systems?

Yes. We support Modbus RTU, BACnet MSTP, and analog (0-10V) control. The system provides real-time monitoring of airflow, static pressure, energy consumption, and individual motor status.
