B-Tohin GS300 High Speed Single Stage Centrifugal Blower 300m³/min 355-630kW
About GS
GS series single-stage high-speed centrifugal blower is specially designed for waste water treatment aeration.Meanwhile,it is available for medium,such as air,nitrogen,nitrogen dioxide and other non-corrosive gases.
Gs blower is characterized by wide applicability, significant energy saving,small area and easy installation,operation and maintenance.
The B-Tohin GS300-(1.5-2.0) High Speed Single Stage Centrifugal Blower is designed for large-scale industrial air supply applications. Featuring advanced centrifugal compression technology and an optimized aerodynamic design, this industrial turbo blower provides high-volume airflow and stable pressure performance.
With an airflow capacity of 300 m³/min, a pressure range of 50–100 kPa, and motor power options from 355 kW to 630 kW, the GS300 is suitable for demanding industrial operating conditions.

Blower main parts
1,Inlet guide vane device
Compsed of nine vanes, the inlet guide vane device is installed before impeller and its open degree is controlled by an electric operator. When the electric operator receives 4-20mA signal from control panel, it adjusts the vanes' open degree(the value of open degree is both shown on the panel of electric operator and on the control screen) so that the inlet guide vane device can work before gas flows into the impeller aand realize the function of airflow adjustment of 45-100%.
2,Volute
The most suitable volute runner is adopted for reliable pneumatic performance, high efficiency and for achieving all the multivariate efficiency to 85%.
3,Step-up box
Helical type step-up gear is equipped.The gare is diffusion hardened and of excellent performance under high-speed rotation and long service life.
Bearing of sliding type with Babbitt metal surface is adopted.The bearing takes lubricant film for supporting its shaft and cooling.It is featured with low friction,high antiknock characteristic,reliable performance and longevity.
4,High efficiency impeller
The impeller, which is ternary mixed semi-open type, is designed by the three-dimensional theory . The curve for the impeller is selected recurring to simulate
working condition on computer, and better fitting for the actual flowage of gas. Meanwhile, it reduces the vane deformation caused by centrifugal force and improves the efficiency reliability.
The advances connection type is adopted for the impeller and high-speed shaft.Before delivery ,impeller over-speed and dynamic balance tests are taken for ensuring the high performance of blower.
The material of the impeller is optional, aero-metal or stainless steel or other materials available according to the custom's requests.
Blower structure
Gs series centrifugal blower features single-stage cantilever,axial inlet and radical discharge structure. Air comes into the suction pipe and the inlet guide vane device from the inlet filter setting.Main driving motor is connected with the coupling and the step-up box.When start,
the step-up gear drive the ternary mixed semi-open impeller to make gas for power,and the gas discharge out through vane-less diffuser and volute chamber.
