SAFETY FIRST
• Misuse of these devices can result in serious injury.
Potential Dangers
• Compressed air accidentally blown into the mouth can rupture the lungs, stomach or intestines.
Death
• Direct contact with compressed air can lead to serious medical conditions and even death.
Low Pressure
• As little as 12 lbs. of air pressure can blow an eye right out of its socket.
To prevent accidental injury when working with compressed air.
• Always were your Personal Protective Equipment (PPE).
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.
Spinning Type Ball
• Most are used to propel and pull line around elbows with a spinning action.
Whip Type Agitator
• Can be used in metal and insulated ductwork.
Plastic Duct Plugs (seals access points)
• Make sure they are fire-rated plugs before you buy them.
• Great for getting your air tools to different sections of duct.

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.
