POPULA DKT系列空调风扇已安装在马来西亚电子工厂

A leading electronics component manufacturer in Penang, Malaysia was experiencing persistent issues with its existing air handling unit (AHU) fans: high noise levels, reduced airflow, and rising energy bills. The factory’s cleanroom environment required stable temperature and humidity for sensitive production processes. After evaluating several options, the facility chose the POPULA DKT series air conditioning fan as the replacement solution. Learn more about POPULA fan products for HVAC applications.

Challenges Before Replacement

  • Existing fans produced 72 dB noise, causing worker fatigue and requiring ear protection in non-production areas
  • Airflow had degraded by 20% over three years due to worn bearings and inefficient motor design
  • Annual energy consumption for ventilation was 58,000 kWh at high cost
  • Cleanroom temperature fluctuated by ±2°C, affecting product yield

The POPULA DKT Solution

POPULA engineers replaced four old AHU fans with the POPULA DKT series air conditioning fan – an external rotor centrifugal fan designed for compact, high‑efficiency operation. The DKT series features a low‑noise impeller, a high‑efficiency IE3 motor, and a corrosion‑resistant coating suitable for cleanroom environments. Installation was completed over a weekend to avoid production disruption, and the new fans were commissioned with variable speed drives for precise airflow control.

Measurable Results (After 3 Months)

  • Noise reduced from 72 dB to 58 dB – a 14 dB drop, well below factory limits
  • Airflow increased by 15% at the same motor speed, allowing lower speed settings for further energy savings
  • Energy consumption cut by 12% – annual projection drops from 58,000 kWh to 51,000 kWh
  • Temperature stability improved to ±0.5°C, boosting product yield by 2.5%
  • Payback period estimated at 18 months based on energy savings alone

“The POPULA DKT series air conditioning fan has transformed our cleanroom environment,” said the factory’s facilities manager. “Noise complaints have stopped, our electric bill is noticeably lower, and the production team is very happy with the stable conditions. We are already planning to upgrade another production hall next quarter.”
