Why Cleanrooms Need Special AHUs
Driven by chips, pharmaceuticals and bioengineering, cleanrooms demand a controlled micro-environment. The air handling unit is the core that performs filtration, heat exchange, humidification and supply.
Defining Characteristics
- Very large airflow—tens to hundreds of air changes—filters particles and microbes and requires a strong, thick-panel cabinet.
- High fan pressure to overcome 700–800 Pa of three-stage filter resistance, with low leakage to save energy.
- Precise temperature and humidity control via PI/PID and hydrophilic coils for process stability.
- Strict pressure control: positive for most cleanrooms, negative for hazardous or flammable processes.
Applications
These units serve electronics, pharmaceuticals, healthcare, food and defence, where product quality and safety depend on a reliable, clean air supply.
