Component Characteristics Options
  • Standard airflow direction is from the outside to the inside of the cabinet.
  • Filters are stable up to 100ºC and 100% rh. (Filters are necessary to maintain NEMA Rating).
  • Filters guarantee a continuously high level of protection according to EU4, with a 94% separation efficiency according to DIN 24185 Standard.
  • WIth filters, dust capacity is particularly high (620 g/m2), which reduces maintenance.
  • The standard filters consist of a multi-layer grid of corrugated aluminum, securely held in a one-piece aluminum frame. A non-drying adhesive coating traps a high percentage of particulate matter. These filters are reuseable, they may be washed and recoated with the appropriate filter recoating adhesive. Replacements are available for those which become damaged or otherwise non-serviceable.
  • Other supply voltages, both AC and DC, are available on request.
  • Filter fans can be supplied with reversed airflow direction. To order, add "R" after series number. Example: KNP40RF
