This product is used for the following applications:

• Concrete placement in general

• Features

  By extension and distribution, this optional high-frequency equipment increases work efficiency. When a high-frequency vibrator is used, secondary power is extended and distributed at its destinations to ensure an even more effective work environment according to a specific worksite condition.

  Stackable（DB3/ER8030）

  A power distribution box and a cord reel are used to use more than one internal vibrator. The DB3 is for three vibrators, while the ER8030 comes equipped with a 30-meter cabtyre cord on a cord reel. All models are stackable for storage.

  An EP plug and an EC outlet prevent imperfect contact

  Exen’s original new plug (Super Tough Pin, patented) prevents imperfect contact, which used to be responsible for the highest incidence of failure in all high-frequency vibrators, thereby dramatically reducing failures due to single-phase operation. With a new plug and an outlet, you can now loan vibrators to different worksites with peace of mind.

  

  An EC outlet cover

  Accidental disconnection is prevented by using special claws to fix the vibrator to the EP plug completely. This prevents work trouble.

  

  Intermediate cord (used for DB3 types)

  This worksite cord is used to extend the line for the internal vibrator. It is used in combination with a DB3 switchbox.
