The Roots blower is a typical positive displacement rotary blower. It delivers gas forcibly through two synchronously counter-rotating figure-8 impellers. It features constant flow, simple structure and oil-free gas supply, widely adopted as low-pressure air source equipment in various industries.
Working Principle
Two sets of impellers inside the casing rotate synchronously in opposite directions, causing periodic volume change of the working chamber. Air is sucked in when the chamber expands and forced out when the chamber shrinks.
There is no internal gas compression inside the unit. Gas is only displaced by impellers, and pressure rise is achieved by pipeline backpressure. At fixed rotating speed, the output flow barely fluctuates with pressure variation, realizing forced gas delivery.
Main Structure
Key components: precision impellers (2-lobe and 3-lobe types), synchronous gears, casing, bearings, shaft seals and lubrication parts.
2-lobe Roots blower: low cost but severe airflow pulsation and high noise;
3-lobe Roots blower: much lower airflow pulsation, vibration and noise, the mainstream model in current market.
Advantages & Disadvantages
Advantages
Constant air flow: Under fixed rotation speed, air volume remains stable regardless of pressure changes.
Easy maintenance: Fewer components, low vibration and long service life with low operation cost.
Clean gas supply: No lubricating oil mixed with airflow to achieve oil-free delivery.
Cost-effective: Far lower purchase price than magnetic levitation blowers, ideal for small and medium-sized factories.
Wide medium adaptability: Able to convey air, inert gas and other media.
Disadvantages
Relatively high operating noise, which requires supporting silencers and sound insulation covers.
Sharp efficiency drop under high pressure, mainly suitable for low and medium pressure conditions.
Obvious heat generation during long continuous operation, requiring effective heat dissipation.
Application Scenarios of Roots Blowers
Sewage & Environmental Treatment
Used for aeration in biochemical tanks to supply oxygen for microorganisms to degrade organic pollutants in wastewater; also applied for sludge agitation and waste gas collection & transportation.
Pneumatic Conveying Industry
Convey powdery and granular materials in closed pipelines without dust pollution:
Building materials: cement, lime powder transportation
Grain & oil: flour, grain particle conveying
Energy industry: coal powder, biomass powder delivery
Chemical industry: various chemical powder raw materials transfer
Aquaculture
Oxygen aeration for fish ponds, shrimp ponds and aquaculture greenhouses to increase dissolved oxygen in water and avoid fish/shrimp hypoxia.
Industrial Manufacturing
Food industry: raw material dehydration, cooling, air supply for vacuum packaging
Mining: underground ventilation, mineral material purging
Thermal power plants: coal powder conveying, ash silo fluidization
Electroplating & chemical industry: tank liquid stirring, waste gas purging
Vacuum and Other Fields
Vacuum packaging, vacuum adsorption; industrial waste gas collection and tail gas treatment; aeration for black and odorous river remediation; pulp stirring and paper material conveying in paper mills.
