Price listed is for one unit, willing to negotiate/sell as a lot. These are unused BCE-2-96 air curtains, always covered while in storage, never used. Two are 3/4HP units, one is a 1/2HP unit. Similar sized units range in price wildly from 1800-4700, but a unit with similar specs (CFM, HP, etc) can be had new on global industrial for $4,549, before shipping (model numbers #WBB824800/#WBB824703) on GI)
