Reverse Air Blast Assembly
•Air blasts back towards the operator.
•Lightweight hose and nozzle allows the hose to propel itself through the duct away from the operator.

Forward Ball Assembly
• Air blast pushes debris forward, away from the operator and towards the vacuum system.
• Hose is flexible enough to navigate the curves yet rigid enough to prevent the nozzle from curling back towards the operator.

Hoses
• Four types: 1) Rubber: Suitable for the home air compressor and in
agricultural and industrial applications.
2) Nylon: Not suited for high pressure applications, industrial applications, or extended use.
3) PVC: An economical choice and suited for general purposes like painting, inflating, and with tools.
4) Polyurethane: Material of choice for high pressure applications, extended use, and use in industrial situations.
