Product Details

The nVent HOFFMAN EF High Flow Filter Fan is designed for forced-air ventilation of industrial electrical and automation enclosures.

Ambient air is drawn through the filter into the enclosure to remove heat generated by electrical and electronic components such as PLCs, drives, power supplies, contactors and control equipment.

The EF Series is particularly suited to open-loop cooling applications where ambient air conditions are suitable and the external temperature is lower than the desired enclosure temperature.

Key Features

Tool-free click-in installation minimizes installation time and eliminates the need for mounting screws.

Hinged front cover provides quick access for easy filter replacement.

Adjustable airflow direction and connection position simplify installation in different enclosure configurations.

IP54 / Type 12 protection helps reduce the ingress of dust and water when properly installed.

Wide operating temperature range from -40°C to +55°C.

Self-extinguishing thermoplastic front cover, rated UL94 V-0.

Wide airflow range from compact EF100 models up to the high-capacity EF700. nVent
