ROOTS BLOWER- A POSITIVE DISPLACEMENT MACHINE
CENTRIFUGAL BLOWERS & FANS: This Range covers various types of Centrifugal and Axial Flow Fans, which have relatively high air displacement but low compression ratios. They are either of Centrifugal type, Axial flow types or Regenerative types. As their internal clearances are relatively high, the discharge pressures are limited to few inches of water only. These types are generally used for applications requiring high volumes but low pressures such as in Air-conditioning, in furnaces, Low pressure Cooling, Dust or Fume extraction systems, lean phase pneumatic conveying etc POSITIVE DISPLACEMENT BLOWERS (Roots Blowers):- Twin Lobes and Three Lobes type Blowers fall under this category. They have higher POSITIVE DISPLACEMENT BLOWERS (Roots Blowers):- Twin Lobes and Three Lobes type Blowers fall under this category. They have higher efficiency at moderate compression ratios and are most efficient in the compression ratios of 1.1 to 2. They find use in applications, ...
