Premium BTSR Series Three-Lobe Roots Blower
Engineered for continuous, heavy-duty industrial applications, the BTSR series by Jinan Golden Bridge redefines stability in positive displacement blowers. By utilizing an advanced three-lobe rotor design and a unique spiral port structure, it significantly minimizes gas pulsation, resulting in vibration-free and ultra-low noise operation.
100% Oil-Free Air: Specialized structural sealing prevents lubricating oil from entering the casing, ensuring output air is completely clean.
Ultra-Low Noise: The spiral inlet and outlet ports allow gradual airflow, eliminating the drastic pressure changes that cause traditional blower noise.
Exceptional Durability: Features 20CrMnTi carburized gears ground to Grade 5 precision, supported by high-capacity imported double-row roller bearings.
Zero Vibration: Precision-machined rotors undergo rigorous dynamic balancing tests for perfectly smooth performance.
The BTSR Series Roots Blower represents our commitment to high-efficiency, low-carbon, and precision-engineered industrial solutions. Designed for reliability, this positive displacement blower delivers an airflow volume that is strictly proportional to its rotational speed. Compared to traditional two-lobe models, our three-lobe configuration completes three intake and exhaust cycles per rotation, ensuring smaller load variations and higher mechanical strength.
Optimized Spiral Port Design: Old-generation blowers suffer from severe noise due to sudden reverse flow and compression at the exhaust port. The BTSR series incorporates a spiral shielding line, ensuring the rotors open and close sequentially. This gradual compression eliminates drastic pressure spikes, drastically reducing operational noise.
Advanced Composite Meshing: The rotor profiles are designed with an advanced composite meshing curve, offering superior sealing, minimal air leakage, and a significant boost in volumetric efficiency.
Standardized Interchangeability: We employ a complete mass production system. All fan bodies and accessories are standardized, guaranteeing rapid replacement, easy maintenance, and consistent high quality.
