1. Deodorization performance

The treatment efficiency of each sheet type filter varies depending on the type and concentration of gas to be treated. Examples are given below. The product has high treatment efficiency, removing over 90% of the gas in a short period of time of 60 minutes after being left to stand.

1-1. Organic gas (measurement with a sheet)

< Test conditions >

  • Test gas : Toluene
  • Sample size : 200cm²
  • Initial test gas concentration : 100ppm
  • Test gas volume : 30L
  • Test temperature/humidity : 20℃/50%RH

1-2. Basic gas (measurement with a sheet)

< Test conditions >

  • Test gas : Ammonia
  • Sample size : 200cm²
  • Initial test gas concentration : 100ppm
  • Test gas volume : 30L
  • Test temperature/humidity : 20℃/50%RH

1-4. Aldehyde (measurement with a sheet)

< Test conditions >

  • Test gas : Acetaldehyde
  • Sample size : 200cm²
  • Initial test gas concentration : 100ppm
  • Test gas volume : 30L
  • Test temperature/humidity : 20℃/50%RH

2. Pressure loss

Since each sheet in a corrugated filter has a honeycomb structure, the ventilation resistance is low and large air flow processing is possible.

< Test conditions >

  • Number of corrugated cells : 117 / inch²
  • Sample height : 50mm, 100mm, 150mm
