About greenfan®

We Care About Efficiency

greenfan’s products focus on enhancing energy efficiency and indoor air quality in HVAC systems. Our materials, including the Smart Fan Controller (SFC), Efficient Fan Controller (EFC), and +wire® adaptors, are designed to optimize HVAC system performance. The SFC is a standout product, designed to extend off-cycle times, improve thermal comfort, and increase energy savings by adjusting fan-off delays after heating or cooling cycles. These materials use high-quality, durable components that are more reliable and energy-efficient than competitors, while ensuring the longevity of HVAC systems.

Environmentally Focused

greenfan’s products are designed with sustainability at its core. Our solutions, like the Smart Fan Controller (SFC) and +wire®, focus on enhancing energy efficiency in HVAC systems. Our products reduce power consumption by optimizing system performance without compromising comfort. For example, the SFC’s variable fan-off delay technology helps lower energy consumption by ensuring that the HVAC system operates more efficiently. greenfan’s commitment to reducing energy waste and lowering carbon footprints helps consumers save energy while contributing to global sustainability efforts.

Patented Products

greenfan has leveraged its innovation by securing numerous patents that cover the core technology used in their HVAC efficiency products. These include US patents for their Smart Fan Controller (SFC), +wire® adaptors, bipolar ionizer, and Smart Economizer®. Our company holds a significant patent portfolio (e.g., US Patents 8763920, 9328933, 9500386, etc.) for its variable fan-off delay technology, the fan-on fault detection system, and advanced algorithms. These patents not only protect greenfan’s unique innovations but also help our company stay competitive in the energy-efficient product space.
