Brandýská 8, Jirny u Prahy, tel:+420 281012550, [email protected], www.labox.eu VERTICAL LAMINAR AIR FLOW CABINET The cabinet is designed for applications requiring laminar air flow in order to protect the product against particle and bacterial contamination. fully automated operation controlled by micro-processor unit, securing optimum parameters of laminar air flow in the working area of the cabinet ideal for sterility checkouts, cultivation, etc. large working space high reliability CONSTRUCTION easy to clean The cabinet is equipped with a motor ventilator with electronically controlled electromotor. The speed of the blower is controlled by microprocessor unit, which scans the velocity of laminar flow, and keeps it at the value set in the programme. The scanned velocity is simultaneously displayed on the control unit display on the cabinet control panel, together with the information of supplied output of the electromotor, e.g.: velocity 0.45 m/s (output 55 %). The above described solution reduces significantly power consumption. Unlike motors, speed of which are controlled by thyristor voltage controllers, this concept consumes only such amount of power which is necessary to achieve the flow rate selected. As standard, cabinet are supplied with programmed velocity of 0.45 m/s. Upon request, the velocity can be adjusted within the range of 0.2 to 0.6 m/s. This programme change can be, upon customer´s request, also executed by service technician for the already delivered and operated cabinet.. The equipment of the cabinet with very efficient ventilator and continuous automatic speed regulation allows long-time keeping of required air flow rate with high accuracy, despite successive filter contamination, thus optimally utilizing its service life. The working board of the cabinet is made of rust-proof steel, the cabinet is lit by side and front window from the surrounding area and also by fluorescent lamp installed underneath the front panel. Electrical safety is increased by means of earth-leakage breaker.
