Vitamix Aer Disc Container 48 oz BPA-Free Dishwasher-Safe Fits All Full-Size

The Aer's incredible speed and versatility are made possible by a deceptively simple innovation: the patent-pending Aer disc. Liquid ingredients are pulled through small holes in the spinning disc, aerating and emulsifying them, while firmer ingredients like ice, fruit, and herbs are agitated but not puréed. New in box.
