NSR-Ⅱ-T Sealed Roots Blower

Sealed Roots Blower Product Introduction

Our company has developed a special sealed roots blower that is particularly suitable for transporting special gases such as biogas. Compared to a regular Roots blower, this product has the advantages of good sealing, stable flow rate, low noise, small size, high efficiency, energy saving, and stable operation. In addition, the blower’s interior is coated with special anti-corrosion materials and uses imported German seals to effectively resist the sulfur corrosion of biogas and achieve a perfect sealing effect. This product is suitable for transporting flammable and explosive gases such as gas, hydrogen, acetylene, carbon dioxide, etc. After being introduced to the market, it has received high praise from a wide range of users. The selection parameters for biogas booster blowers can be based on the parameters of NSR-II blowers.

Industry Requirements

In the face of the need for conveyor belts corrosive, toxic and other special gas industries
Our company has developed a stainless steel + mechanical seal blower.

Industry Applications

This series of blowers Adopt imported bearing positioning to ensure reliable axial positioning of fan impeller and Easy to adjust. The over-flow parts of the fan are all made of 304SS, 316L, duplex steel 2205 and other special materials according to different gases and working conditions. 304SS, 316L, duplex steel 2205 and other special materials are used. Impeller and machine The impeller and casing adopt the whole casting structure and machining center processing, with high precision. (No need to repair and fit during assembly).
The seal form is various, including N type, K type, NR type, KR type, E type. NR type, KR type, E type and other sealing forms. Can be transported containing water hydrogen chloride, hydrogen sulfide and other corrosive toxic gases. Hydrogen sulfide and other corrosive toxic gases.
