The co.'s touchless pressure differential pot uses a vacuum-pressure system to move product. Its dense and semi-dense phase system requires no compressed air for conveyance, no motorized feeding devices such as rotary air locks and no compressed air booster fittings along the pipeline that increase wear on pipe and elbow fittings. A 20-in. access port makes cleaning and maintenance easier.
