Development of a Filtering Respirator with a Real-Time Monitoring Device for Pressure Drop
Abstract
Purpose. Development of a filtering respirator with a device for operational pressure drop control.
Method: The development of the filtering respirator with a real-time monitoring device for pressure drop involves the use of the following equipment: the ESP32-C6-LCD-1.47 microcontroller with a video display, and the MPXV7002DP FRS pressure sensor, which enable monitoring of the pressure drop caused by dust accumulation, based on determining the critical filter resistance value.
Findings. A real-time monitoring device for pressure drop in the respirator filter box has been developed. It provides prerequisites for improving worker safety in hazardous conditions and extends the possibilities of personalizing respiratory protective equipment according to specific operational requirements and users’ physiological characteristics. The developed algorithm of the device enhances the protective properties of the filtering respirator by timely informing the user about the pressure drop status of the filter, which is associated with half-mask tightness and battery charge level. A mathematical model has been proposed, correlating filter parameters, breathing mode, and the characteristics of the pressure drop sensor, which allows for determining changes in the pressure drop across the filter element depending on dust accumulation on the filter surface. This makes it possible to control filter service life by comparing it with the critical pressure drop value.
Paper type. Experimental studies of filtering respirator’ performance indicators.
