The following is a comparative summary of the performance and characteristics of AC FFU and DC FFU based on six dimensions:
Energy Consumption
AC FFU: Generally, the power is about 180 watts, with three-speed regulation. If the number of FFUs in a clean room workshop exceeds 100, the energy consumption will be relatively high during long-term use.
DC FFU: The brushless motor has a power of about 100 watts, with significant energy-saving effect, which can save a lot of electricity bills in long-term use.
Noise
AC FFU: The motor vibrates at high frequency during operation, resulting in relatively large noise.
DC FFU: The brushless motor has no friction, so the noise is low.
Control Precision
AC FFU: With three-speed regulation, it needs to be adjusted manually one by one, with low efficiency and limited control precision.
DC FFU: It features stepless speed regulation and can be controlled in groups. It can adjust the rotation speed according to the number of indoor particles, with high operation efficiency and high control precision.
Initial Cost
AC FFU: It has low cost and is suitable for the construction of short-term clean booths.
DC FFU: The motor and control system are complex, so the initial cost is high.
Long-term Cost
AC FFU: The electricity fee and maintenance cost are high (due to high power).
DC FFU: It is significantly energy-saving, has a long service life, and the long-term cost is low.
Intelligent Control
AC FFU: Intelligent control relies on additional equipment.
DC FFU: It supports IoT integration, group control systems, etc., with a high degree of intelligence.
To sum up, if the clean room is used for a long time, DC FFU has obvious advantages in energy consumption, noise, control precision, long-term cost and intelligent control; if it is for short-term use, AC FFU is a better choice due to its low initial cost.
