  1. An Introduction to Industrial Vacuum Trucks & Air Movers Gary W. Toothe, CET, CIT

  2. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT What Is The Difference Between… • A Vacuum Truck • An Air Mover ?

  3. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Vacuum Trucks • Vane Pump Driven • Pressure/Vacuum Rated Body • Evacuates the Air Inside • Material Fills the Vacuum

  4. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Vacuum Truck Applications • Liquids • Sludges • Low Air Movement, So Air “Kills”

  5. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Air Movers • Positive Displacement Blower • Very Low Pressure Inside • Greater Airflow (2600 – 6000 cfm) • High Wind Speeds (156 – 624 mph)

  6. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Air Mover Applications • Solids • Semi-Solids • Liquids • “Air is King”, Have to “Breathe”

  7. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Does An Air Mover Work? • Lift & Carry • Collect & Filter • Transport & Dump

  8. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Lift and Carry • Vacuum (“Hg) = Lift • Air Flow (CFM) = Carry • Horsepower Divided Between Lift & Carry

  9. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Is Vacuum Measured? • Inches of Mercury (“Hg) • 1” Hg About 13.3” Water • 27” Hg = 3 ½ Story Building (29.93 feet)

  10. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Is Air Flow Measured? • Cubic Feet per Minute • A Box 12” x 12” x 12” = 1 cu. ft. • So… 5,000 CFM = 5,000 Boxes per Minute

  11. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT You Can’t Have It Both Ways • Horsepower = “Hg (Lift) x CFM (Carry) Constant • Spend Them on Lift OR • Spend Them on Carry

  12. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Does An Air Mover Work? • Lift & Carry • Collect & Filter • Transport & Dump

  13. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Collect And Filter • The Vacuum Line • The Collector Body • The Filtration System

  14. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT The “Vacuum Line” • Pipe • Smooth Bore Hose • Corrugated Hose

  15. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Big Is The OpeningIna Hose? • The Area of a Circle (pi x radius squared) For an 8” Hose, the Opening = 16 pi For an 6” Hose, the Opening = 9 pi For an 4” Hose, the Opening = 4 pi For an 2” Hose, the Opening = 1 pi • Your Math Teacher Was Right! You Do Need This Stuff!

  16. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT The “Vacuum Line” • Size Matters • Stay As Big As You Can for As Long As You Can! • Once You Start… Don’t Stop! • Smaller Hose Increases Velocity, Not Capacity

  17. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Collect And Filter • The Vacuum Line • The Collector Body • The Filtration System

  18. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT The Collector Body • Inspection Door for Dry • Float Level for Liquids • Float Shutoff for Liquids • Unloading Valves/Pumps

  19. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT The Collector Body • Huge Air Velocity Drop • Deflector Re-directs • Must Be Level • Air Exits to Filters

  20. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT The Collector Body • Always a Confined Space! • Start as Permit Required • Tailgate Safety Prop • Empty or Residue ONLY! • Bad Air Can Keep It Permitted

  21. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Collect And Filter • The Vacuum Line • The Collector Body • The Filtration System

  22. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Filtration • Collector Body • Cyclones • Bags

  23. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Filtration • Collector Body Is Primary Stage, >95% of Material is Removed From the Air Stream Exit to Filtration ><

  24. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Filtration • Cyclones are Secondary Stage, ~3% of Material is Removed From the Air Stream • Centrifugal Force, Think Hurricane Eye Wall • Must Have “Dead Air” to Work

  25. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Filtration • Bags are Final Stage, <2% of the Material is Removed From the Air Stream • Blow Down System • No Caking, No Holes

  26. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT How Does An Air Mover Work? • Lift & Carry • Collect & Filter • Transport & Dump

  27. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Transport & Dump • DOT Considerations • Dump Site Issues • Cleaning After Dumping

  28. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Transportation Issues • DOT Exemptions • Vehicle/Load Weights • Liquids Present? • Hazardous Material/Waste?

  29. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Dump Site Issues • Level Ground • Stable Ground • Overhead Power Lines

  30. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Cleaning After Dumping • Tailgate Safety Prop • Gaskets & Surfaces • Float & Shut Off Ball

  31. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Safety Considerations

  32. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Who Sets The Rules? • OSHA Has No Vacuum Regulations • The General Duty Clause: • “shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees” • WaterJet Technology Association • Recommended Safety Practices For Industrial Vacuum Services • Vactor/Guzzler Safety Manual

  33. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT What Are the Hazards? • Confined Spaces • Suction Injuries • Static Electricity • Mixing Materials • Safety Labels

  34. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Confined Spaces • Start as Permit Required • Tailgate Safety Prop • Empty or Residue ONLY! • Bad Air Can Keep It Permitted

  35. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Suction Injuries • Perfect Vacuum = 30” Hg • Outer Space ~ 30”Hg • Like Sticking Your Arm Out a Hatch on the Space Shuttle

  36. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Suction Injuries • Tissue Damage • Blood & Body Fluids Pulled through Skin • Great Weight Loss Plan… Lousy Life Expectancy

  37. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Suction Injuries • Vacuum Break • Close to Technician • The One On the Truck Is to Save the Truck • Never Use a Bucket

  38. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Static Electricity • Dry Material + High Speed + Insulated Hose = Static • Wind Speeds at 4,800 cfm • 8” 156 mph Cat 5 Hurricane • 6” 277 mph F5 Tornado • 4” 624 mph > Mach 0.8 • Insulated Hose (plastic)

  39. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Static Electricity • Grounding Cable • Grounding Point • Metal Pipe & Fittings • Wire Reinforced Hose

  40. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Mixing Materials • Chlorinated + Ammoniated = • Chemical Reactions • Cross Contamination • Wet & Dry Together

  41. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Safety Labels & Proper Procedures • Read the Book! (Manual) • Obey the Signs! (Labels) • Know the Controls

  42. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT Where to Learn More • Federal Signal – Guzzler • Other Manufacturers & Suppliers • WaterJet Technology Association • Me (Gary W. Toothe, CET, CIT)

  43. An Introduction to Industrial Vacuum Trucks & Air Movers By Gary W. Toothe, CET, CIT We have time for a few questions… Who has the first question?
