The VACU-BIN Self-Emptying Material Handling Bin is specifically designed for vacuum loading systems using pick-up wands to load dry, free-flowing material. The VACU-BIN allows material to unload without creating "starvation" holes at the vacuum wand pick-up front. The VACU-BIN is designed to allow material to flow freely to the lowest point in the bin where the material can be easily picked up by the vacuum wand. Three models are available: SEB-100 (110 lb. capacity), SEB-300 (300 lb. capacity), and SEB-500 (500 lb. capacity). The VACU-BIN is designed using high-density polyethylene and is supplied with lids and manufactured with heavy-duty casters.
