Silica dust clogging test equipment Silica Dust

automaticrespirator

Test equipment SILICA DUST is to test HEPA filters designed for powered air-purifying respirators (PAPRs) according to procedure № RCT-APR-STR-0025 NIOSH. Operation: Test equipment consists of a silica dust chamber with anthropometric dummy human head, a breathing machine, a dust generator, measuring system for dust concentration in the chamber (aspirator), a cleaning air system from dust. The necessary test conditions are created in the silica dust chamber, and the breathing machine simulates human external breathing and creates a pulsating, sinusoidal-like airflow. An absolute filter captures all the dust that has passed through the HEPA filters during the test. As a result of the 4 hours test, the amount of dust that goes through the absolute filter is fixed, determined the total amount of leakage thus the resistance to constant airflow of the respirator after dusting is checked. Features Unique platform for research & quality control of RPE Modern way of control: to control the test equipment, an application is used the app on personal computer with a simple and convenient interface in English. It is possible to quickly and easily master the control of SILICA DUST and involve even a laboratory intern in the work. Saves time for lab staff: the software automatically maintains test parameters, records and stores their results, and saves staff time. Lightweight design and advanced ergonomics
