About Us

The working chamber consists of two parallel cylindrical bores containing two impellers, with two lobes whichh counter rotate without touching each other, or the casing. Heavy duty gears ensure that a correct clearance is maintained between the impellers. The working chamber requires no lubrication hence the medium handeled deos not get contaminated with oil.

These machine are manufactured in our morden woks at Vatva, Ahmedabad, This is a SLM Manek Lal design

Salient Features of Roots Blowers

  • ROOTS INDIA COMPANY make Twin Lobe Compressors (RIC & SJI Series) This blower design is 100% interchangeble & replecment agaist SLM-Maneklal blower design. ROOTS INDIA COMPANY Complete range from 50m3/hr to 12000 m3/hr. Suitable for different pressure upto 1 Kg/cm2 in Single Stage and upto 2.2 Kg/cm2 in Double Stage. Also suitable for Gas Duty as well as Vacuum Duty (Upto 600 mbar).
  • ROOTS INDIA COMPANY make blower technical feture : The Main Body, Side Covers are manufactured from Graded Cast Iron as per I.S. 210 / FG - 260. Castings. For corrosive gases we supply blower in C.I. construction with electro less nickel plating on contact parts or complete blower in stainless steel construction.
  • All components are machined to very accurate dimensions with extremely tight tolerance with guaranteed interchangeability including with components of  SLM-Maneklal make machines. The Castings of Casing and Main Covers (Bearing Housing) are stress relieved after pre- machining for dimensional stability at elevated temperature. The Castings of Casing and Main Covers (Bearing Housing) are stress relieved after pre- machining for dimensional stability at elevated temperature.
  • The Lobes of Rotors are having involute profile ensuring Uniform clearances between rotor to rotor in any position of two rotors. The profile also ensures uniform clearances between Casing and Lobes unlike providing PTFE strips which is usually done as a cheap method of manufacturing for maintaining clearances.
  • The Rotor profiles are machined in imported Copy Shaping/Planning Equipment ensuring profile with high accuracy/finish which result inpower saving. Sealing of main chamber is by labyrinth seal. Four numbers piston rings are fitted on each side of rotor.
  • Both side of side casings are oil filled. All bearings and gears are splash lubricated. This increases life of bearings and gears.
  • The Timing Gears are wide for more load bearing, and having helical teeth, hardened and ground, maintaining backlash within the limit of 0.03 to 0.06 mm to ensure low noise level. Same are either Press-fit on rotor shafts by Tensioning Element or having taper locking on rotor shaft by hydraulic system making mounting and dismounting of Gears much easier.
  • Bearing on the driving Shafts have Spherical Taper Roller Bearings to take axial as well as thrust load whereas the gear Shafts have Angular contact Ball Bearings.
  • The Gears as well as the bearings are oil lubricated on both sides of the Blower.
  • ROOTS INDIA COMPANY models are suitable for vertical as well as horizontal flow. In case of vertical flow compact assembly requiring no additional internal piping is being given.
