In CRUMA vertical laminar flow, the flow of air passes through a HEPA H-14 (manufactured according to EN-1822) at a constant speed, passes the cabin in laminar and in the vertical direction, generating a Class 100 sterile area (according to Federal standard 209E and American standard equivalent to ISO Class 5 standard) and protecting the product from external contamination and cross-contamination between samples. Filtration system one step with minimum efficiency 99.995% for particles of 0.3 mm on top and removal of 100% of the air flow outward.rr- More information on the LCD display: date, time and countdown timer, date of next review, counter cumulative number of hours of work and cabin filter.
