EVP - ZG SERIES ROOTS BLOWER

Description: ZG Blowers with tri-lobe are heavy duty style new products based on MB blowers which technology is from America.


Introduction:

ZG Blowers with tri-lobe are heavy duty style new products based on MB blowers which technology is from America. It is the replacement for Duroflow models of Gardner Denver, RAM/RCS models of Dresser Roots, and RBS models of Robuschi.

Advantages:

High blower speed with 4000 to 5000 rpm, high efficiency, and compact structure design

Low noise tri-lobe rotor

Noise-reduction know-how application for casing Integral-shaft ductile iron impellors

Dual splash lubrication

Over sized cylindrical roller bearings

Hardened teeth face for precision helical timing gear, taper-lock shaft mounting Versatile configuration

Piston ring air seals Lip type viton oil seals

Air cooling, aluminum oil tank

Automatic belt tensioner and integrated discharge silencer base frame application for the blower package Ductile cast iron pulleys are applied to meet the high speed

Start up valve is optional to realize the blower starting without load even if without bypass air release valve.

Applications:

ZG series roots blowers are widely used in sewage treatment, coal, cement, petrochemical, smelt, oxygen making, pneumatic conveying, electric power.
