Our FLB type rotary blower is a medium-pressure, medium-capacity compressor used for gas transportation.
Currently, the applications of the fluid being used are expanding to various gases. As a manufacturer specializing in rotary blowers, we are striving to meet your needs by utilizing the best manufacturing techniques under a new design policy.
A magnetic coupling is used in the shaft penetration section. Since there is no shaft penetration section, gas leakage is eliminated.
A rotary blower that employs a magnetic coupling at the shaft penetration part, achieving a seal-less design. By eliminating the shaft penetration part, gas leakage is resolved. It is suitable for use in severe environments where leakage is not permitted. 【Benefits】 - Can be used in severe environments such as nuclear-related applications where gas leakage is not allowed. - The lifespan of the magnetic coupling is semi-permanent. - Maintenance costs can be reduced due to extended lifespan. ◎ For more details, please refer to the PDF document or feel free to contact us.
No leaks! Seal-less design with magnetic coupling at the shaft penetration! Recommended for gas pressure delivery.
The "FLB-MC Series" is a rotary blower that employs a magnetic coupling in the shaft penetration section, achieving a seal-less design. Since there is no shaft penetration section, it is leak-free. It is suitable for applications where leakage is not permitted, such as gas pressure delivery. Additionally, the lifespan of the magnetic coupling is semi-permanent, reducing maintenance costs. 【Features】 ■ Compatible with various materials such as stainless steel, special cast steel, plating, and Teflon lining ■ Oil-free ■ Achieves long lifespan for the shaft sealing section *For more details, please download the catalog or contact us.
