Felt Cover heater F11 for OS30/32


  • The special felt cover F11 can be spliced with solar aluminum alloy collector OS30/32 and installed on a flat roof or wall.
  • The air through the black felt gap (air intake volume remains unchanged) can efficiently absorb the heat of the sun, thereby increasing the temperature of the outdoor fresh air entering the room.
  • As long as the felt cover is spliced, the temperature of the fresh air entering the room can be increased: F7----about 10℃; F11----about 15℃; F11h----about 15℃.
  • After a long period of outdoor dust and rain test, the air intake volume is reduced by up to 3%. It can effectively filter Dust and become clean after rain washing, no maintenance is required.
  • The service life is more than 5 years.
