Service Life of the NBC-77 SOF® Gas Mask Filter
Breakthrough time of a gas mask filter is tested according to EN 14387+A1 at 70% relative humidity and a flow rate of 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium-heavy work. The approximate lifetime (usage time) of the NBC-77 SOF® filter may, under normal conditions, be estimated by comparing the concentration at the workplace with the minimum Dynamic Adsorption Capacity (DAC) specified for the filter.
Gas Mask Filter Storage and Maintenance
Each NBC-77 SOF® gas mask filter is sealed in a plastic bag by the manufacturer. Store the filters unopened in a clean place at a stable temperature, ideally between -5 °C and +30 °C with relative humidity below 80%. Sealed filters tolerate conditions from -30 °C to +50 °C with relative humidity below 95%. The storage period (month and year) for filters is marked on the filter label.
Do not attempt to regenerate the filters. Never clean the filters with compressed air or water, as this can damage the filtration media and compromise protection.
