Ventilation Equipment Manufacturers
Why Leading Ventilation Equipment Manufacturers Choose YENSHEN?
From climate-controlled ventilation for livestock and horticulture, to factory heat exhaust, emission control, and high static pressure requirements for dust collection—core needs remain the same:
Adjustable airflow, precise temperature control, energy savings, and quiet operation.
YENSHEN provides highly customized Brushless DC Motor (BLDC) solutions, engineered to match fan blade characteristics with fine-tuned speed control. Our intelligent controllers enable real-time adjustments to maintain a stable operating environment.
Core Technology Advantages
Co-Designed Motors and Fan Blades — Breaking Convention
We collaborated with top universities in Taiwan to develop optimized fan blade geometries. Unlike the conventional approach of selecting blades based on the fixed speed of induction motors, we reversed the process—leveraging the stepless variable speed of BLDC motors to precisely match blade characteristics. This maximizes airflow efficiency and minimizes noise. Additionally, BLDC motors are one frame size smaller than induction motors of the same power, reducing airflow obstruction and enabling smoother air passage.
Lower Energy Use and Noise — Greater Reliability and Lifespan
"Our optimized motor–blade pairing significantly reduces power consumption, noise, and vibration. It is ideal for agricultural and horticultural operations, extending product lifespan and minimizing the risk of motor failure—ultimately preventing costly downtime."
Multi-Function in One Motor — Simplifying Inventory
Compared to traditional induction motors, which require different motor core sizes to accommodate different power ratings (e.g., 200W and 400W needing two separate models), our high-efficiency BLDC motors can cover a wide power range within the same physical size. By adjusting winding parameters and magnet grade, and pairing with controllers of varying output levels, a single motor model can support multiple applications—greatly reducing the number of product variants and overall inventory.
Tailored Blades and Advanced Features for Every Application
- Cooling Fans: Wide-dispersion blades with long airflow reach; optional dual-fluid mist nozzles for enhanced heat dissipation
- Ventilation & Exhaust: Focused airflow and high static pressure design for optimal indoor air exchange
- Smart Detection: Built-in PM2.5 and filter-clogging sensors for dust collectors via the controller’s real-time monitoring system
Challenges & Solutions
Unstable Airflow
Conventional induction motors are prone to speed fluctuations due to voltage instability, turbulence, or backpressure—causing inconsistent airflow and poor temperature control. Our BLDC system ensures precise speed control for consistent performance.
Excessive Energy Consumption
Conventional induction motors tend to have low efficiency. When combined with poorly designed fan blades and airflow channels, the overall performance of the ventilation system suffers—resulting in significant energy loss, hidden operational costs, increased mechanical load, and frequent maintenance.
Limited Cooling Effect
Traditional cooling fans mainly rely on airflow to lower the temperature, which limits their effectiveness. We have introduced twin-fluid atomization technology that produces ultra-fine mist droplets. These droplets disperse quickly and evenly throughout the space, absorbing heat and evaporating rapidly to accelerate cooling. At the same time, this technology does not increase ambient humidity. Because the mist particles are extremely fine, the twin-fluid nozzle can operate twice as long as a conventional nozzle with the same amount of water, significantly reducing the need for frequent refills.
Noise and Vibration Issues
Most fans on the market use generic blades paired with induction motors, leading to a mismatch between motor speed and blade characteristics. This often results in excessive noise and vibration. Additionally, since induction motors operate at fixed speeds, they frequently run within the system's resonance frequency range. This not only compromises user experience but also accelerates wear on the bearings and the entire unit, ultimately shortening the product’s lifespan.
