Best Screw Blower
1. It adopts multiple patented technologies such as counter-flow devices, and the structural design is advanced and reasonable.
2. The impeller adopts a specially designed three-blade composite profile, which is highly efficient.
3. The processing accuracy of key components is high, ensuring the smooth operation of the blower (vacuum pump).
The ZSR/ZSH series products include the ZSR/ZSH single-stage high-pressure Roots blower and the ZSH-V single-stage dry high vacuum Roots vacuum pump. The ZSR/ZSH series of products are based on the advanced structure of the RR series of Roots blowers produced by drawing on and absorbing the introduced technology, adopting our company's proprietary invention patents "Structure of Multi-Blade Impeller Positive (Negative) Pressure Roots Blower with Counter-flow Device" and "New Structure of Roots Blower and Vacuum Pump with Counter-Flow Device". Based on our company's over 40 years of design and manufacturing experience, we have independently developed a new generation of single-stage high-pressure ratio Roots blower (high vacuum Roots vacuum pump).

Main technical indicators
Single-stage high-pressure Roots blower flow rate: 5.2-169.5m ³ /min Pressure rise: 88.2-147kPa
Single-stage dry high vacuum Roots vacuum pump flow rate: 2.9 to 166.4m ³ /min, vacuum degree: -49 to -78.4kPa.
Series ZR large-size high-pressure rotary blower and Vacuum Pumps is developed based on rich manufacture experience,which is a advanced product to be satisfied with customer’s requirement of large capacity and high pressure rotary blower. It is not only absorbed the technology soul from series RR rotary blower. which is introduced technology and series L rotary blower, but also adopted the special rotor profile, which makes rotary blower be high efficiency and energy saving.
Features
Rotor with approximate involute profile, advanced and reasonable, high efficiency overall.
Main parts are machined by machining center and NC facilities, among which bearing reaches to class 5 accuracy. The product is high accuracy and runs reliably.
Oil tank has new structures of oil-plate etc., good heat emission. Cooling water isn’t used when pressure rise doesn’t exceed 49kPa,which can lower occupating expenses.
Casing and headplate adopt misplit structure in horizon, which can make check and repair convenient.
Performance Range
Pressure Rise: from 9.8 kPa to 98 kPa Capacity: from 317.9m/min to 1292m3/min
Vacuum Degree: from -13.3 kPa to-53.3 kPa Capacity: from 353.4m3/min to 1308.5m3/min
