While most portable air conditioning units operate by turning off the fan when the compressor is not running, there are some models available that offer a "fan-only" mode where the fan can run continuously without the compressor. However, it's important to note that the availability of such features can vary among different manufacturers and models. Here are a few manufacturers that are known to offer portable air conditioning units with continuous fan operation:
Whynter: Whynter is a brand that offers various portable air conditioning units. Some of their models, such as the Whynter ARC-14S, come with a fan-only mode that allows the fan to operate independently of the compressor.
De'Longhi: De'Longhi is another reputable manufacturer of portable air conditioners. They have models like the De'Longhi Pinguino PACN135EC that include a fan-only mode, enabling continuous fan operation without the compressor.
Honeywell: Honeywell offers a range of portable air conditioning units, and some of their models, like the Honeywell HL14CESWK, provide a fan-only mode for continuous fan operation even when the compressor is off.
It's important to carefully review the product specifications and features of individual models from these manufacturers or others to ensure that they offer the specific functionality you are looking for. Reading customer reviews or reaching out to the manufacturer directly can also provide more detailed information about the fan operation options available in their portable air conditioning units.
