4. SAFETY FIRST
• Misuse of these devices can result in serious
injury.

5. Potential Dangers
• Compressed air accidentally blown into the
mouth can rupture the lungs, stomach or
intestines.

6. Death
• Direct contact with compressed air can lead to
serious medical conditions and even death.

7. Low Pressure
• As little as 12 lbs. of air pressure can blow an
eye right out of its socket.

8. To prevent accidental injury when
working with compressed air.
• Always were your Personal Protective
Equipment (PPE).

9. 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.

10. 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.

11. Spinning Type Ball
• Most are used to propel and pull line around
elbows with a spinning action.

12. Whip Type Agitator
• Can be used in metal and insulated ductwork.

13. 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.

14. Hand Held Blow Guns

15. Pneumatic Engines
Reading manual provided with your pneumatic motor ensures:
• proper care
• avoids maintenance challenges
• decreases down time
• peak performance of the motor

micron

17. 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.

18. Inside Diameter
• Inside Diameter is very important to the duct
cleaning technician.
• Most common sizes are 1/4”, 3/8”, 1/2” and 1”
