These VBH Compact cabinets from Steril are used to work with EN12469 standards and are safe to manage for all sorts of special treatments. This uses a front opening that works with 30% air aspiration standards at a 0.40 m/s velocity or greater. The rest of the air will move through a HEPA filter in order to keep the air clean. This is also made with a front opening that works with all APF standards and is used with one of the best standards possible. The microprocessor will also review all the data in a unit including the air flow velocity and exhaust rate and position of where the front screen is, thus keeping the air in check as it is moving.
