Malvern 3000 Enclosure with Carbon Filtration designed to provide personnel protection during particle size analysis using a Malvern 3000** with a Nilfisk Vacuum connected to the rear of the unit. Design accommodates ergonomic loading sample into the Malvern LV and subsequent loading of Malvern LV into the Malvern 3000 for analysis. Features a waste chute for removal of waste and (2x) removable rear panels for removal of processed product. Sliding doors are also removable to facilitate ease when unloading equipment, particularly the Malvern 3000.

      Enclosure features include:

  • Organic carbon filtration
  • (4x) iris ports on sides and rear of enclosure for cord/cable entry
  • Integrated airflow velocity alarm which notifies the user when face velocity is lower than the setpoint calibrated by the certifier
  • Blanked port for optional retrofitting of additional waste chute

Recommended face velocity is 70-80 linear feet per minute (lfpm) at the plane of face opening while operating under specified house exhaust volumetric flow rates.
