Often regarded as the "heart and lungs" of modern environmental infrastructure, Transfluid Roots Blowers are heavy-duty, positive-displacement rotary lobe pumps engineered to displace large, consistent volumes of air at low-to-medium pressures.
Specially manufactured for continuous, 24/7 duty cycles, our blowers serve as the primary source of process air in Effluent Treatment Plants (ETP), Sewage Treatment Plants (STP), aquaculture setups, and pneumatic conveying lines. By utilizing perfectly synchronized, non-contacting internal rotors, Transfluid blowers deliver a completely stable, uniform stream of 100% oil-free compressed air that remains unaffected by changing downstream liquid depths or backpressure variables.
Key Technical Features
-
Guaranteed 100% Oil-Free Air Output: The compression chamber operates entirely without internal lubrication. Precision-ground timing gears located in external, oil-sealed casings maintain perfect rotor alignment without contact, eliminating any risk of oil mist polluting biological aeration tanks or fouling fine-pore diffusers.
-
Constant Volumetric Displacement: Unlike traditional centrifugal fans whose airflow drops sharply when backpressure rises, Transfluid positive displacement blowers deliver a steady, predictable air volume regardless of changing liquid levels or system resistance.
-
Advanced Tri-Lobe and Twin-Lobe Options: Available in classic Twin-Lobe configurations for rugged mechanical simplicity, or advanced Tri-Lobe configurations that feature specialized helical discharge ports to reduce pressure pulsations, structural vibrations, and operational noise.
-
Thermally Stable Cast Iron Casing: Rigidly constructed from high-tensile, close-grained cast iron (Grade FG 220/260) with integrated heat-dissipating ribs to eliminate structural distortion during prolonged high-temperature operations.
-
Oversized Bearing Assembly: Fitted with heavy-duty spherical roller and deep-groove ball bearings on both ends to absorb severe axial loads, ensuring an extended mechanical lifespan and minimal maintenance downtime.

Core Applications
-
Wastewater Aeration Ecosystems: Supplies continuous dissolved oxygen (DO) to sustain active aerobic microbial cultures inside MBBR (Moving Bed Biofilm Reactor), SBR (Sequencing Batch Reactor), and conventional Activated Sludge Process (ASP) tanks.
-
Filter Backwash Air Scouring: Provides high-velocity air bursts to agitate and loosen trapped particulate matters inside Multi-Grade Sand Filters (MGF) and Activated Carbon Filters (ACF) during maintenance cycles.
-
Grit Chamber Aeration: Drives precise fluid velocity parameters within wastewater grit channels to cleanly separate inorganic gravel while keeping organic compounds suspended.
-
Sludge Agitation: Keeps sludge holding wells uniformly mixed to prevent settling, anaerobic digestion, and septic odor buildups before the dewatering stage.
-
Pneumatic Conveying Systems: Reliably moves dry powders, cement, lime, fly ash, and plastic granules through enclosed industrial pipelines.
