Chiye Fan
Industrial Grade Mechanical Fans
High-efficiency axial and centrifugal solutions optimized for high flow rates, structural endurance, and dynamic static pressure balancing.
Navigating Global Ventilation Challenges in Modern Commercial Infrastructure
In large industrial plants, commercial kitchens, and manufacturing facilities, maintaining Indoor Air Quality (IAQ) is no longer just a comfort standard—it is a critical regulation compliance issue.
Modern ventilation relies on precise fluid dynamic calculations. High volume flow rates must overcome substantial system resistance caused by duct runs, filters, and terminal units. For system engineers, choosing between axial and centrifugal fans is a calculated trade-off between pressure generation and volume throughput. Commercial exhaust fans are designed to perform reliably under high static pressures, corrosive environments, and extremely high temperatures, ensuring continuous operation under the most demanding conditions.
- Optimized specific fan power (SFP) to meet energy reduction mandates.
- Dynamic impeller balancing (ISO 1940 standard) for vibration-free operations.
- Compliance with stringent noise control and environmental protection regulations.

Proven Performance in Key Commercial Spaces
From removing high-temperature grease to ventilating confined spaces, here is how our industrial fans meet demanding real-world conditions.
01. Kitchen Extractors & Grease Control
Commercial kitchens produce hot air laden with grease, humidity, and combustion byproducts. Standard fans quickly clog, leading to motor failure and fire hazards. The I3-48 and DFA Centrifugal Fans are designed with backward-curved, non-overloading impellers that resist grease buildup. Constructed from heavy-gauge steel and optioned with clean-out doors and drainage ports, these units ensure reliable operation in high-grease environments.
- Easy-to-clean impeller configurations that reduce down-time.
- Out-of-airstream motors that stay protected from heat and grease.
- High static pressure output to overcome long grease duct filters.
02. High-Temperature Fire & Emergency Smoke Control
In emergencies, life safety depends on keeping emergency pathways clear of smoke. The HTF Fire Protection Fan Series is certified to withstand temperatures up to 280°C for over 30 minutes. Installed in underground parking lots, shopping malls, and industrial complexes, these dual-purpose fans provide regular ventilation day-to-day and switch to emergency smoke extraction when triggered by fire alarms.
- Tested under high-thermal stress to meet global fire safety codes.
- Robust housings that resist thermal distortion.
- Direct or belt-drive options tailored to local building regulations.
The Future of Industrial Ventilation
Developing next-generation ventilation technology with a focus on smart control, materials science, and energy efficiency.
1. Smart EC Motor Technology
We are transitioning our core product lines toward Electronically Commutated (EC) motors. EC technology delivers up to 30% greater efficiency than traditional AC motors, allowing for smooth speed control and simple integration with modern Building Management Systems (BMS).
2. Aerospace-Grade Blade Aerodynamics
Using Computational Fluid Dynamics (CFD) simulation tools, our research team designs blade profiles that minimize turbulence. The result is increased airflow capacity, lower noise levels, and reduced wear on internal drive components.
3. Sustainable & Corrosive Resistant Materials
For specialized chemical processing facilities and marine environments, we have expanded our line of 304 and 316 stainless steel fans. These products are built to resist corrosive vapors, extending service life and lowering long-term maintenance costs.

Industrial Ventilation FAQ
Answers to common engineering questions regarding the selection, installation, and maintenance of commercial exhaust fans.
Formula: CFM = (Volume × ACH) / 60.
For example, commercial kitchens typically require a high ACH (between 15 and 30), whereas storage warehouses may only require 4 to 10 ACH.
Centrifugal fans draw air in and push it out at a 90-degree angle, using centrifugal force to build pressure. They are best suited for ducted systems, filtration setups, and high-resistance environments like grease extractors.
High-Pressure & Special-Purpose Exhaust Fans
Premium centrifugal, multi-wing, and high-pressure configurations built for industrial extraction, boilers, and commercial kitchen setups.
