What volt-power supply is required for a negative air pressure unit or cabinet?

The required power supply for a negative air pressure unit or cabinet typically falls within the standard voltage range suited for most residential and commercial settings. A 115-volt supply is commonly used as it is standard for many electrical devices and equipment. This voltage supports the efficient operation of the motors and fans within the negative air pressure system, ensuring optimal airflow and proper functionality.

Using a 115-volt power supply is beneficial as it aligns with the electrical standards most prevalent in the United States, making it readily available and widely compatible with existing electrical infrastructure. Other voltages, like 220 or 240 volts, tend to be used for larger machinery or industrial applications, which are not as common for negative air pressure units designed for basic air filtration and ventilation purposes. Hence, 115 volts is the most appropriate and practical choice for such units.
