Not recommended. The fan is used to circulate heat. Operating without the fan will lead to localized heat accumulation and reduce heating efficiency and service life.
Periodically wipe dust off the fan and PTC heating surface. Inspect wires and terminals for looseness or corrosion, especially for outdoor cabinet installations.
It supports long-duration continuous operation. However, you need to match a proper thermostat to turn it on/off based on temperature. Regular dust cleaning is required if deployed in dusty outdoor environments.
