21. The efficiency of roots-blowers is lower than that of thoroughly designed turbo-compressors and is approx. 70%.
 The efficiency of thoroughly designed turbo-blowers comes up to 80%. 

22. Turbo Blower Advantages
the efficiency of thoroughly designed turbo-blowers is higher than that of roots-blowers;
on account of  the characteristic curve, the velocity of the conveying air can be varied;
in the partial-load range, the velocity of the conveying air remains rather constant, i.e. wear on the conveyor pipe and the conveying material is lower;
the conveying air flow is continuous. The high-frequency noises can be dampened with little expenditure;
the running wheel is resistant to foreign matter, i.e. complicated filter equipment can be avoided;
the sensitivity to higher air temperature is low.
Turbo Blower Disadvantages
a turbo-blower starts more slowly than a roots-blower;
the energy demand in the partial-load range is higher than that of the roots-blower.

23. Roots-Blower Advantages
a roots-blower quickly attains the full number of revolutions;
the power demand in the partial-load range is lower.
Roots-Blower Disadvantages
in the range of partial load, the conveying speed is higher, i.e. wear on the conveyor pipe and breakage of the conveying material will be greater;
a conveying speed once chosen can only be altered with considerable expenditure;
due to the low-frequency noises (pulsating conveying air flow), expensive noise dampening equipment will be necessary;
in order not to exceed the operating pressures, a control device must be installed;on account of the narrow piston clearance,
the roots-blower is sensitive to foreign matter, i.e., filter cleaning of the conveying air is required;
after a longer period of use, the piston clearance becomes larger and leads to capacity losses.
