เอวีร่อน TIMER PNC-12N

 

  Description (standard model) 

  Only pneumatically the device controls the pulse valves
  for in the case of explosion proof condition or no electric   
  condition. The 54 series pulse valves are connected to the
  pressure chamber of the controller  by small bore airlines.    
  The wiper arm assembly of the controller is operated by a  
  pneumatic ratchet drive. It pauses between valve
  connections for a preset time which is adjustable by the
  user. The pulse time is also user adjustable by means of a   
  throttle valve accessed after removal ofthe bottom casing.
  During the pulse time the  wiper arm passes beneath a
  valve connection port and vents the pilot line to that  
  particular valve. The valve opens and remains open until the wiper arm moves on to the next position.  
  The pilot air is vented through the port marked "R" underneath the manual override knob, which is marked   to show the exact position of the wiper arm.

  The interval is adjusted by a pneumatic timer through the front hole of the unit and the switching
  time adjusted as described above.

  Fluid (control section): Fitered air-compressed air supply via conditioning unit with a 5 to 10 with air
  filter, without oiler (for unpurified compressed air we recommend an additional 50 to 75 primary filter.)
