The HV650 Automatic can be delivered with one of two power settings. The supply of compressed air can be either 240 CFM or 400 CFM. This will change the suction velocity and power to recover your waste. At 240 CFM the suction velocity will be approximately 2200 CFM at the hose end. With the high powered 400 CFM configuration it will increase to approximately 3600 CFM. Either setting will be determined by the type of waste and the length of the hose desired and the diamatre of the hose.

All waste behaves differently when recovered by high powered vacuum systems. The air flow and vacuum required to pull a certain type of waste can range between 10" Hg to 20" Hg to be effective. Air flow could also need to be high with a certain kind of waste or lower with another kind of waste. The velocity that waste either wet or dry enters the hopper can determine the type of filter cartridges and the filter area cubed that is required. We have 30 years experience in building venturi systems. When Vacteck build a unit, we build it to a specific task and adjust the settings accordingly.

The Hopper Vac 650 automatic has a sophisticated timing sequence provided by the world leader in this type of air powered timing systems, FESTO. The unit vacuums and then at a pre-determined interval it switches to filter cleaning and waste removal via the auto dump valve. The timing can be adjusted to every different need.

The hose length is determined by the power delivered to the Vacteck Transverse Thrusters and the waste that needs to be recovered. The Hopper Vac 650 Automatic comes standard with 10 metres of German Polyflex anti-static hose.
