Why Choose the nVent HOFFMAN EFAE250-300R5 EMC Exhaust Filter?
The nVent HOFFMAN EFAE250-300R5 is a high-performance EMC vertical exhaust filter designed for ventilation of compatible electromagnetic compatibility (EMC) electrical enclosures. It provides filtered airflow while helping maintain the enclosure's EMC performance, making it particularly suitable for industrial control and automation systems containing sensitive electrical and electronic equipment.
Featuring a G4 filter mat with a filtration efficiency greater than 90%, the EFAE250-300R5 helps prevent dust and other contaminants from entering the enclosure through the ventilation opening. Its IP54 protection rating supports dependable use in industrial environments where protection against dust and water ingress is required.
The filter requires a 224 × 224 mm cut-out and has a depth of 38 mm. Its convenient click-in mounting system simplifies installation without conventional screw fastening, while an integrated stainless steel EMC screen and contact strips help maintain electromagnetic shielding when correctly fitted to a suitable EMC enclosure.

Reliable EMC Ventilation for Industrial Enclosures
Effective enclosure ventilation is important for dissipating heat generated by electrical and electronic equipment, but conventional ventilation openings can compromise electromagnetic shielding. The nVent HOFFMAN EFAE250-300R5 combines filtered ventilation with an integrated EMC screen, helping preserve the shielding characteristics of a compatible EMC enclosure.
For correct EMC contact, the cutting-edge surface around the enclosure opening needs to be blank. The filter may be used as part of a natural ventilation arrangement or combined with compatible EFE filter fans for forced ventilation, providing a flexible thermal-management solution for sensitive industrial electronic systems.
Typical Applications
- EMC electrical and electronic enclosures.
- Industrial control and automation cabinets.
- Variable-speed drive and power-electronics enclosures.
- Machine-building control systems.
- Industrial communications and instrumentation equipment.
- Enclosures requiring filtered ventilation while maintaining EMC shielding.
