Step 1

2" Inlet Cuff ---- Enables use of a 2" Hose

OSHA's Silca Dust Rule Recommends a 1-1/2" or 2" Hose, see Overview below.

2" Soft Vinyl
Inlet Cuff
#D2020S

    $10.00

For all models:  Bosch, Hilti, Makita, Metabo, Milwaukee, Nilfisk, many others.

FACT:  The 2" tank inlet opening on vacuums is over 2" but manufacturers supply a 1-1/4" hose which reduces CFM.

Our 2" Soft Vinyl Cuff fits the above vacuums and enables you to use a 2" hose (cuff has an internal 2" thread) .

Advantages of using a 2" hose vs. 1-1/4"?  See Step 2.

 

Step 2

2" Hose ---- Our USA Made 2" hose is more flexible than an imported 1-1/4" hose.

With a smooth interior it assures maximum airflow vs. a ribbed interior hose that accumulates with dust, restricts airflow and becomes heavy.

Vacuum Replacement Hoses, 1-1/2" and 2".

2" x 25' Hose
#233060

    $90.00

2" Vacuum Hose - Super Flexible, Lightweight & Durable
  • A+ for tuck pointing, drilling, chiseling, sawing, hand grinding
  • Sold in 25' lengths, typically cut to the length you need
  • Advantages of using a 2" hose:
    • by maintaining the tank’s 2" inlet orifice the vacuum’s CFM is maintained at the end of the hose where it matters
    • a reduction from 2" to 1-1/4" causes debris to clog at the reduction point
    • the motor will perform as designed and prevent excessive amp draw and tripped circuit breakers.

 

Step 3

Connection Cuffs---- to the Dust Shroud

Thread-on  X  Smooth-end (attaches to dust shroud)

Perfect fitting hose cuffs and replacement hoses.Universal - Simply Your Life, Reduce Inventory
  • Easy “thread-on” hose connections vs. using proprietary cuffs
  • USA Made, High Quality, Soft Vinyl Cuffs:  one end threads onto the 2" hose, the other end has a smooth interior to fit onto a dust shroud
  • Thread-on cuffs eliminate proprietary connectors and provide a universal system
  • For a cross reference of which screw cuff fits what dust shroud (Bosch, Dewalt, Dust Director®, Hilti, Metabo, USA Dust Guard), see page 5 of the brochure.
2" Screw-On Cuffs
D2020S | 298665

    $10.00
2" Threaded  x  2" ID Smooth
  • threads onto the 2" hose
  • attaches to dust shroud with a 2" outside diameter vacuum port
  • fits:  USA 6" Dust Guard, Dust Director®, Metabo.
  • Note:  this same cuff is used as the 2" Inlet Cuff.
D2015S  |  226652    $17.00

2" Threaded  x 1.5" ID Smooth
  • threads onto the 2" hose
  • attaches to dust shroud with a 1.5" outside diameter vacuum port
  • fits:  Bosch tuck point shrouds, 5" and 7" cup wheel shrouds.

 

Step 4

Air Pulse Filter Collection Bag  ~  "Now Your Vac Will Work"

 Best Upgrade You Can Make ~ Guaranteed! 

USA Dust Guard - Air Pulse Bags:  prevents filter loading, keeps HEPA filter clean!

#136514

    $60.00
per 5 Pk

    $500.00
per 50 Case

Stronger, Better Quality, Superior Durability & Filtration
  • Outperforms & outlasts any other type of dust bag 10:1
    • collect a lot more powder without suction drop or the bag tearing

    • collects dry and moist debris at the same time

    • productivity increases, bag consumption decreases

    • bag will not burst or tear in the tank - provides assurance against dust escaping into the room

    • keeps the HEPA cartridge clean!

  • Fits any 8 to 17 gallon tank with a 2.5" OD deflector port (photo, right) including:
    • Bosch - all models including their 300 CFM vacuum
    • Dewalt - both models
    • Hilti 300 CFM model and those with an inlet port in the tank
    • Makita, Milwaukee, Nilfisk, Ridgid, Shop Vac, others
  • This single upgrade will transform a simple $60 W/D Vac into a $500 Dust Extractor.

 

 

Vacuum Inlet Port.Overview:  The inlet opening on vacuums (wet/dry and large concrete polishing dust extractors) ranges from 2" to 3".

Using a 1-1/4" hose reduces CFM plus it creates other problems, the effect is similar to kinking a water hose:  flow or CFM is reduced to increase pressure or H20.

Additional problems created by using a 1-1/4" hose with a 2" Inlet:

  • CFM is reduced at the end-of-the-hose which increases visible dust exposure at the dust shroud

  • the reduction creates a clogging point for debris

  • the motor works harder, operates louder and overheats, all of which increases amp draw and causes circuits to trip.OSHA Fact Sheet - Recommended Hose Size.

FACTS:

  1. Using a 1-1/2" or ideally a 2" hose will increase the vacuum's CFM at the end-of-the-hose

  2. Eliminating the reduction at the inlet port eliminates excessive amp draw and prevents debris from clogging

  3. OSHA's Silica Dust Regulation recommends using at least a 1-1/2" hose - see OSHA Fact Sheet, page 1.
