• The efficiency of roots-blowers is lower than that of thoroughly designed turbocompressors and is approx. 70%. • The efficiency of thoroughly designed turboblowers comes up to 80%.
• • • Turbo Blower Advantages the efficiency of thoroughly designed turbo-blowers is higher than that of rootsblowers; 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.
• • • 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.
