Blowvacc Roots Blower/Pumps are synonyms for reliability, availability and maintainability.
Blow kings Blowers specialises in the manufacture of industrial air blowers, based on the renowned Roots design, which have been in production for over 10 years and have a reputation for reliability and long service life.
Our engineers have a combined experience of over 50 years in the manufacture of Roots type blowers, most of whom worked originally at Busch, Edwards, Everest, SMT & KAY who then became Kings and finally Blow kings, before the entire production, including specialist machinery was moved to Blow kings Blowers in New Delhi India.
There's our expert staff who knows about Roots type blowers very well and they are pleased to discuss your requirements and assist you with product selection.
In addition to the manufacture of blowers, we carry out specialist sub-contract machining on large cast components, including CNC, VMC, planing, boring and grinding.
Our Super Heavy Duty series blowers are based closely on the original design of Roots types’ blower, with their renowned reliability and life expectancy.
Cast iron cylinder and head plates.
Impellers are made from SG iron and are cast with integral shafts or pressed in steel shafts
Precision ground and hardened steel spur gears, taper/straight mounted onto the impeller shafts
Oversize bearings for long operational life.
Grease lubricated double row bearings or spherical roller bearings (size dependent) .
New - oil-oil lubricated versions also available .
Sizes and capacities .
The conservative load carrying capacity of the larger diameter rolling element bearings ensures an extended operating life. Timing gear life is also extended by controlled lubrication systems .
The computer calculated impeller profiles ensure maximum volumetric efficiency with minimum absorbed power without sacrificing torsional rigidity. The high rigidity of the impeller / shafts permits a higher pressure rise to be obtained than with other machines of comparable size.
The generous shaft diameter keeps drive stresses low.
Gear and shaft strength is substantially increased by the use of taper/straight mounted gears which do not need keyways for location. Setting of the gear wheels to obtain correct timing of the impellers is simplified, a feature that facilitates field maintenance.
Precision ground and hardened steel gears are used to ensure smooth, silent running and accurate timing of the rotating impellers.
A controlled lubrication system is provided to ensure efficient operation without waste of energy in the gear case.
Specially designed rotary oil seals are used in the gear case. This feature eliminates maintenance associated with the use of lip seals.
Design and manufacture is in accordance with metric standards.
Use as an Exhauster If used as an exhauster and dust or liquids could be drawn into the machine due to inadequate filtration, closed end rotors should be specified. This will minimise risk of loss of dynamic balance due to material inside the rotors.
