Hapman offers a full-line of pneumatic vacuum conveyors, featuring three large capacity units in addition to the standard size conveyors. Hapman pneumatic conveyors are engineered to move high volume bulk material in a short period of time without the need for plant air. Featuring an integral PD pump to generate the necessary vacuum, Hapman’s vacuum conveyor allows a single operator to move material from unload or storage into the process quickly and effectively. The Hapman vacuum series has a unique latched side door for easy access to the internal filters. This latched panel allows for fast filter inspection and changes with no tools.
