A dry boom is effectively a sprayer boom that is fed only by hoses, and does not include any liquid filled boom pipe. Conversely, a boom that is fed by pipe/tube is generally referred to as a “wet boom”.
Dry booms are typically used with smaller sprayers, as they can provide lightweight, low footprint spray booms for less complicated sprayer needs.
