INFINAIR TRINITY-LEAN smart fans are good examples of INFINAIR fans that feature green technologies. Energy consumption is growing with the development of science and technology. It has become a key topic around the globe to save energy and reduce emissions for better environment. INFINAIR smart EC fans are right products at the right moment. EC (Electronic Commutation) fans refer to fans with Brushless Direct Current (BLDC) motors that accomplish commutation electronically.

INFINAIR EC fans have the following distinguishing features compared with AC (Alternating Current) fans:


1. Stepless Variable Speed

AC fans are not automatically adaptive to various operating conditions. So additional hardware (such as the variable frequency drive) is needed to change fan speed. INFINAIR EC fans require lower costs in this respect. With the drive controller or the top-level control system, the stepless variable speed function helps EC fans meet various operating conditions in real time, requiring no additional hardware.


2. High Efficiency

INFINAIR smart EC fans are over 30% more energy-efficient at both high and low speeds than AC fans that generally work with low efficiency and great energy loss.

3. Strong Compatibility

By virtue of the drive control system, EC fans can operate in a wide voltage range and run on AC / DC power supply, compatible with 50Hz / 60Hz power sources. This strong compatibility is one of the advantages EC fans have over AC fans.


Reliable quality and stable operation of INFINAIR EC fans are ensured through strong R&D, advanced manufacturing processes and professional tests, including water spray and splash test, high and low temperature test, sound test, salt spray test and environmental simulation test.


η1: Impeller of High Efficiency: INFINAIR Bionic Aerodynamic Technology

Product engineer: With its rich experience in the ventilation industry, INFINAIR has successfully overcome many technical challenges. In designing INFINAIR EC fans, we figure out the aerodynamic model of the impeller through studying bionics. Also, the CFD flow field simulation technology is adopted to assist with blade shape design. Tests conducted in the AMCA accredited air chambers help ensure reliable aerodynamic performance of the impeller.


η2: High-efficiency Motor: INFINAIR EC Motor Technology

Motor engineer: EC motors are quite an important component of EC fans. The permanent magnet technology is used on EC motors to avoid loss of excitation and rotor loss. INFINAIR EC motors have been optimized further for better electromagnetic design to ensure highly efficient operation. Wide performance range of high efficiency allows stable and reliable running under various operating conditions.


η3: High-efficiency Controller: INFINAIR Smart Control Technology

Drive control engineer: To make sure motors run at the operating points of high efficiency, we have iterated the drive control system to the 3rd generation of INFINIAIR electronic commutation algorithm. Greater reliability is thus achieved, requiring no position sensors. Standard industrial communication interface allows remote monitoring through Industrial Internet of Things.


The triple combination of impeller, motor and drive control represents the working philosophy of INFINAIR TRINITY-LEAN EC fans.It has become an irresistible trend to develop a low carbon economy. INFINAIR with its TRINITY-LEAN smart fans is an EC specialist for you.
