LV (limit values) - MAC = maximum particle concentration in the workplace.
2)
Provided the gas absorption based on the highest permissible gas concentration for gas filters in powered air supplying unit of 0.05%
in vol of gas filter class 1 – 0.1% in vol of gas filter class 2 - and 0.5% in vol of gas filter class 3 will not be exceeded.
Filters used with Honeywell powered air purifying
The Honeywell filters and their classification, for application with Honeywell Powered Air Purifying Respirators, are clearly identified in the
user manual of systems (Compact Air 200 part no. 1793676 and Compact Air part no. 1793677)
After use
-
Store the filters in a cool, dry, location with the caps attached
-
The maximum permissible storage period is specified on the filter
-
Storage temperature range: -20°C / +50°C
-
Maximum humidity during storage: 80%
-
Before disposing of seal off both filter openings
-
When disposing of the filter take in mind that there are hazardous substances present in the filter
