Abstract

High protective efficiency of filters (fine purification filter-element) used in microbiological laboratories ventilation systems contributes essentially to biological safety provision. Filters are to be tested at bench-top devices prior to application. The existing models of these devices allow to test no more than 8 filters per working day, and require considerable physical efforts. The proposed automated device allows to test 33 filters per working day and decreases considerably workload of the personnel.

Summary

Introduction

High protective efficiency of filters (fine purification filter-element) used in microbiological laboratories ventilation systems contributes essentially to biological safety provision. Продолжаются изыскательские работы по созданию новых эффективных фильтрующих материалов с целью изготовления на их основе новых высокоэффективных фильтров тонкой очистки воздуха (ФТО). Наибольшее применение для высокоэффективной очистки воздуха находят фильтры на основе тонковолокнистых материалов из ультратонких стеклянных и синтетических волокон, металлокерамики, а также базальтового супертонкого (0,1– 0,4 мкм) волокна [3]. В нашей организации эффективность фильтрэлементов тонкой очистки воздуха (ФЭТО) оценивают с использованием S. marcescens и уранина.
