The CTH EVO model cabins produced by ALS are of the triple-stage absolute filtration type and are in Class II, as they are equipped with a partial frontal working opening allowing the suction of 30% of the air at a minimum speed of 0.40 m/s and a recirculation system for the remaining 70%, which is sent to the working area in laminar flow at a speed between 0.25 and 0.5 m/s (as defined by the DIN-12980 and EN 12469: 2000 standards).

Performance

  • Protection of the operator: The containment index, evaluated over the total surface area of the frontal suction area, is equal to or less than 5 CFU for a non-turbulence test or APF equal to or greater than 1x105 according to EN12469.
  • Protection of the product: Cleanliness of the air in the working area in Class ISO 3 as per ISO EN 14644-1
  • Protection of the environment: This involves filtration of the expelled air quota with EN 1822 compliant HEPA H14 filters with an efficiency of 99.995% MPPS (equivalent to 99.999% on 0.3m particles with DOP/DOS test)
