B-Tohin Launches the BKH Series Permanent Magnet Integrated Roots Blower

As a professional blower manufacturer, B-Tohin Machine (Jiangsu) Co., Ltd. proudly introduces its latest innovation: the BKH Series Permanent Magnet Integrated Roots Blower.

Featuring permanent magnet direct drive as its core technology, combined with intelligent variable frequency control and customized noise reduction technology, this new-generation blower delivers improved energy efficiency and operational convenience.

Designed for a wide range of applications, including wastewater treatment, pneumatic conveying, and aquaculture, the BKH Series represents a significant advancement in Roots blower drive technology.

Here are its five key advantages:

1. Permanent Magnet Synchronous Motor Direct Drive – Improved Energy Efficiency

The BKH Series features an integrated direct-drive design combining a permanent magnet synchronous motor with the Roots blower air end. By eliminating intermediate transmission components such as traditional belts and couplings, it minimizes mechanical transmission losses and achieves transmission efficiency close to 100%.

Compared with conventional Roots blowers driven by standard motors, the integrated permanent magnet drive design offers significant energy-saving potential, helping businesses reduce long-term operating costs and achieve better energy efficiency.

2. Compact Integrated Design – Reduced Installation Space

The motor and blower air end are highly integrated into a compact structure, resulting in a smaller footprint and easier installation.

The optimized configuration also allows greater flexibility in pipeline arrangement. For equipment upgrades and installations in space-constrained facilities, the BKH Series provides an efficient air supply solution while minimizing installation space requirements.

3. Low-Noise Operation – Improved Working Environment

The permanent magnet motor operates smoothly with reduced vibration. Combined with optimized blower rotor profile design and an integrated vibration-damping structure, the BKH Series delivers lower operating noise under comparable working conditions than conventional Roots blowers.

This helps create a more comfortable working environment and makes it easier to meet industrial noise control requirements.

4. Belt-Free Drive – Reduced Maintenance Costs

Traditional Roots blowers using belt-driven transmission systems may experience belt wear, slipping, or breakage, requiring regular tension adjustments and replacement.

The BKH Series adopts a direct-drive configuration, eliminating belt-related maintenance requirements. This helps reduce equipment downtime, spare parts consumption, and labor costs while improving operational convenience.

5. Intelligent Control – Smarter and More Flexible Operation

The BKH Series supports variable frequency speed control, allowing airflow and pressure to be adjusted according to actual operating conditions.

This enables on-demand air supply, helping avoid unnecessary energy consumption caused by oversized equipment operating under partial load.

The system can also be integrated with PLC or DCS control systems to support remote monitoring, fault warnings, and automated operation management.
