Top Flow 3 is a double fan, double side operated vertical laminar airflow cabinet, with partial recirculation. This unit is manufactured like a Class II microbiological safety cabinet with 0.40 m/s mean LAF velocity, front opening inward air velocity more than 0.40 m/s and visual/acoustic alarms in compliance to European standard EN 12469: 2000.
Top Flow 3 is specifically designed for manipulating and passing of mice or other experimental animals, from dirty cages to clean cages, in a sterile area, with protection for operator, animal and environment. An electrical driven lifting system of the whole cabinet allows the optimum ergonomic worker posture.
Main and Exhaust HEPA filter: H14, 99.995% efficiency MPPS according to EN 1822 (99,999% DOP test efficiency at 0,3 ?m);
Main and Exhaust filters HEPA are fitted according to negative seal principle to avoid any escape of contaminated particles and they are testable with DOP for filter integrity).
Pre-filter (F5) installed below the working surface, to extend filters life and to prevent blockage of motor blower
Cleanness of air in working area is class ISO 5 @ 0.3 and 0.3 ?m particles according to ISO EN 14644-1 (Class M3.5/100 according to FS209E).
