Most competitors use an "open" rotor design on their disintegrators.

SEM pioneered the use of SOLID STEEL Rotors, making them standard equipment on every Disintegrator Value Kit we offer.

 

Some will argue that the decision to use a Solid Rotor instead of an Open Rotor is merely a matter of preference. The fact is, Solid Rotors are far superior to open rotors in paper destruction applications.

 

THE SEM SOLID ROTOR

- Designed to stand up to the rigors of paper destruction
- 3 times the rotational inertia of same size open rotors
- 3 times the torsional strength of same size open rotors
- Robust Design provides greater shear force / less fatigue
- More blade fastening points minimizes risk of "peel back"
- No gaps to collect undestroyed paper - Critical for high
  security appilcations

 

 

 

 

COMPETITIVE OPEN ROTOR

- Originally designed for plastics destruction - NOT PAPER
- Less weight means less rotational inertia / shear strength
- Fewer fastening points - increased susceptibility to
  alignment problems
- Voids or gaps can collect undestroyed paper causing both
  "peel back" and information security issues

 

 

 

 

 

 

DON'T FORGET ABOUT OUR KNIVES

 

SEM Disintegrators feature 3/4" thick heat treated knives. Competitive units typically use less durable 1/2" thick knives.
