Louver Damper

  Type LD-J

The damper is designed to operate without any failure at an operating pressure of 1.1 time the admissible operating pressure.


  Housing
       stainless steel or galvanized steel
       1.5 mm thick, by means of a screwed Construction


 
  
Warp-resistant hollow body lamellas made of aluminium, 150 mm, decontamination painting as  option
  Lamellas equipped with changeable silicon rubber profile

  Counter rotating lamellas by means of outside positioned rod. Rod made of stainless steel

  Electrical-, pneumatic-, and manual actuator available. Unless otherwise agreed the dampers will be  delivered assembled with actuator. Dampers with electrical actuator have to be connected according installation instruction of the electrical actuator. Limit switches are adjusted in factory, but have to be connected electrically for operation. Dampers with pneumatic actuator have to be connected to the compressed air supply (quality, quantity, pressure etc.) according installation instruction of the  pneumatic actuator

  Maintenance-free operation

  As all synthetic materials also the silicone seal of the damper is subject to senescence. This is  decisive influenced by surrounding conditions and cannot be forecasted       in any way




  ND-J

  The damper is designed to operate without any failure at an operating pressure of 1.1 time the admissible operating pressure.
