FAQ – Common Questions About Filter Fans
When are filter fans the right choice?
Filter fans are the right choice when excess heat can be handled through ventilation without the enclosure needing to be completely closed.
- Low to moderate heat load in control cabinets and control cabinets
- Clean or controlled ambient air where air can be taken into the enclosure
- Energy-efficient cooling of electronics and control systems
- Cost-effective solution compared to active cooling
When might other solutions be more appropriate?
Filter fans are not the right solution for all applications. Choose other air conditioning when the requirements are higher.
- High heat load or requirement for precise temperature control → cooling unit is more suitable
- Dirty, humid or aggressive environment where incoming air risks contaminating the enclosure
- High ambient temperatures where ventilation is not sufficient
When is a filter fan sufficient instead of a cooling unit?
When the heat load is low to moderate and the ambient air is clean enough for ventilation.
Do filter fans affect the enclosure class?
Yes, the enclosure class is affected by the selected filter fan and correct installation. Choose a solution adapted to the environment.
Do filters need to be changed regularly?
Yes, filters should be checked and replaced as needed to maintain airflow and function.
Can filter fans be controlled with a thermostat?
Yes, filter fans can be combined with thermostats for automatic temperature control.
