A commercial AHU lost 20% airflow within one month. FANOVA diagnosed the root cause: a fixed-speed AC fan unable to compensate for multi-stage dynamic resistance. The FG3G350-2APL-90 EC axial fan retrofit restored 100% airflow, saved 400+ kWh/year, and reduced noise to 63 dB(A). Full PQ curve analysis and before/after results included.
Petroleum mines faced methane and corrosion risks with standard impellers. FANOVA engineered an SS316 centrifugal impeller with elastic coupling and isolated bearing housing—achieving ATEX/GB 3836 compliance, eliminating spark ignition, and extending service life in H₂S/Cl⁻ environments. Discover the safety triad behind zero-failure ventilation.
A food additive plant faced repeated fan failures due to rusting brackets and plastic joint wear. Solution: custom IP65-rated, all-304 stainless steel FG3G630 EC axial fan with potted control board and metal-on-metal mounting. Achieved zero failures, 3,000+ kWh/year savings, and full HACCP-compliant exhaust. Discover the engineering breakthrough.
HVAC systems faced noise and energy inefficiency challenges. Xhengxin’s intelligent EC fans delivered precise speed control, lower noise, and smoother operation—improving ventilation performance and energy savings. Discover how.
