Central vacuum system advantages;

A: High precision vacuum , measuring the degree of vacuum in the pump port can reach 30-50pa.(759.5mmHg)

B: the consistency of the degree of vaccum is very stable .

C: vaccum unit maintenance is simple , convenient , time-saving (can be changed once a month oil)

D: the vaccum unit and low maintenance costs , while working for the impregnation chamber environment and health has greatly improved .

Basic parameters of roots vaccum pump

Preformance :

A: high exhaustion speed can be achieved within a wide pressure range.

B: There is no oil in the pump cavity , thus avoiding the oil steam polluting  the vaccum system .

C: Small vibration and noise .

D: Small wearing of machine , thus small drive power .

E: Easy to maitain ad repair at low cost and long service life.

F: Fit for sudden exhaustion of  the vaccum system .

G: Unique processing the technique is used , make the parts easy to exchange.

Instructions of electric automatic control system of central vaccum system

1.    Every 72 hours is considered a cycle (the cycle can be set), and when the cycle time is reached , the main machine and the auxiliary machine automatically to exchange the role,

2.       Automatic vaccum consumption recognition makes it possible to automatically recognize and close all vaccum pumps when all impregnating machine stop working ,without need of manual operation.

3.       Automatic alarm function(sound and light alarm).
