Dry screw vacuum pump

Laibao VARODRY oil-free screw pumpDV100It ensures the required operating pressure, short section emptying, and final system availability and durability, making it particularly suitable for wet or dusty processes. VARODRY is easy to install and connect, and can be easily integrated into new or existing systems. VARODRY is a 100% air-cooled pump that does not require cooling water. Leybold's developers used fewer, validated mechanical parts and components in their designs. VARODRY enables its users to achieve low maintenance requirements, oil-free emissions, and low operating noise in daily operations. In addition, the pump is dry and clean to prevent oil and particle discharge or oil leakage

Product Introduction

It has been widely confirmed that this series of chemical air systems can be used in many evaporation applications to obtain and control air. Its core component is MZ 2C NT chemical diaphragm pump, commonly used in medium-sized empty systems containing "conventional" solvents. The system is equipped with a CVC 3000 air controller with an electromagnetic valve for electronic air control. The exhaust condenser at the outlet has a compact structure, high efficiency, and can achieve nearly 100% solvent recovery effect, effectively recycling solvents while protecting the environment.
