●Characteristics:

1.The gas inlet can be used to pump gas (producing vacuum) and the gas outlet can be used to output gas ( compressed gas). 
It is equipped with brushless DC motor, durable and low interference. It can run continuously around the clock without 
interfering with the surrounding electronic components or polluting power source. Stable performance and high reliability. 
Maintenance-free .Damp gas as the medium is acceptable. No pollution during the gas transmitted as it is oilless operation. 
Corrosive gas is allowed to be input（The material for the parts which come in contact with gas : Glass fiber reinforced nylon ,
EPDM rubber)

2.It can be mounted in any plane.such as horizontal plane, vertical plane, slope.Perfect self-protective function.
It has functions of overheating protection and overload protection.（This function do not apply to Economical version）

3.Easy to adjust the speed of the pump. The flow rate can be changed by freely adjusting the rotate speed of motor through 
electrical control.There are feedback signals about the rotating speed of motor, which indicate the working status and can 
realize closed-loop control，thus facilitate the intelligent control.（This function do not apply to Economical version and 
Simplified version）
