FAQ

What is EC fan and AC fan, and which is better?
EC (Electronically Commutated) fans and AC (Alternating Current) fans are two types of electric motors commonly used in fan applications. Each has its advantages and is suitable for specific purposes. Let’s explore the characteristics of each:

AC Fan:

  • Type of Motor: Alternating Current (AC).
  • Control: AC fans typically have basic speed control options.
  • Efficiency: AC fans are generally less energy-efficient compared to EC fans.
  • Cost: AC fans are often more affordable upfront.
  • Noise Level: AC fans may produce more noise compared to EC fans.
  • Applications: AC fans are suitable for various applications, including residential cooling, industrial ventilation, and HVAC systems.

EC Fan:

  • Type of Motor: Electronically Commutated (EC).
  • Control: EC fans offer precise speed control and can be easily integrated into control systems.
  • Efficiency: EC fans are known for their high energy efficiency, resulting in potential energy savings over time.
  • Cost: EC fans may have a higher initial cost, but the energy savings can offset this in the long run.
  • Noise Level: EC fans are often quieter compared to AC fans.
  • Applications: EC fans are commonly used in applications where energy efficiency and precise control are crucial, such as data centers, cleanrooms, and other industrial settings.

Which is Better:

The choice between EC and AC fans depends on the specific requirements of the application. If energy efficiency, precise control, and lower noise levels are critical factors, EC fans may be a better choice. However, if cost is a primary concern and the application doesn’t require advanced control features, AC fans can still be suitable.

In summary, the “better” option depends on the specific needs and priorities of the application, balancing factors such as initial cost, energy efficiency, control capabilities, and noise levels.

I have an FFU Fan Filter Unit used mainly for cleanroom manufacturing, can I use it for making my Laminar flow hood?
Absolutely! Your FFU Fan Filter Unit, primarily designed for cleanroom manufacturing, can indeed be repurposed for crafting your Laminar Flow Hood.

FFUs, known for their application in sterile isolators, seamlessly integrate into Laminar Flow (LF) hoods as well. Leveraging FFUs (Fan Filter Units) empowers you to meticulously regulate air velocity beneath each filter. Should your hood comprise multiple filters, you gain the flexibility to fine-tune velocities, ensuring uniformity across the board.

There are 3 speeds (low, medium and high). Can you ask the airflow for each of them, for the 1175x575x350 ?
