Recovery, transfer, and container filling of powders... Are you performing these tasks with separate machines? The "Powder Dedicated Multi-Suction Vehicle" from Swell Co., Ltd. consolidates the functions of "suction," "pressure delivery," "container filling," and "powder transport" into one unit. It dramatically improves the efficiency of all tasks related to powders. With this single unit, you can pressure deliver the suctioned powder to tanks up to 40 meters high or directly fill it into bulk bags or drums. This eliminates the need for multiple vehicles and equipment that were previously necessary, contributing to space-saving and cost reduction on-site. Continuous suction operations are possible, ensuring that work is not interrupted, which leads to shortened construction periods. Complex work plans become simpler. 【Features】 ■ Dedicated to powders ■ Performs four roles with one unit ■ Requires fewer materials and less space for operations ■ Assembly time for the hopper is less than one-third of the conventional time
