When choosing the right respiratory protection system, it is important to know precisely what work the user will be undertaking and the risks involved. Environmental factors must also be considered and whether there are specific regulations that have to be followed. On this page we have compiled common questions and information that can help you in your choice. You can also send your question directly to our technical support.

FAQ
In a clean and dry area at room temperature in a tightly sealed container for example a plastic bag.
"There is no simple, unambiguous answer to the question of how long a chemical cartridge lasts. The multitude of factors that influence the service life of the cartridge make more or less every single case unique. It is important that the employer draws up a respiratory protection programme containing clear information about when a chemical cartridge or a particulate filter should be replaced. This is especially important in the case of chemical cartridge, since these lose their purifying effect when they are saturated. Using smell or taste as a sensor is not always feasible, because many substances have no clear properties of smell or taste. Below are a number of factors affecting the service life of a chemical cartridge. Concentration: The concentration of the substance is a very important factor in assessing the service life of a cartridge. A high concentration means a shorter service life, and a low concentration means a longer one. Humidity and temperature: Humidity and temperature are important parameters, and high humidity generally shortens the service life of a chemical cartridge. Warmer air and high humidity contain considerably more water per unit volume. Contamination and mixtures of types of contamination: Contamination and mixtures of types of contamination affect cartirdges to different extents. The service life of cartridges therefore differs between different work environments. Air volume, i.e. the user's physical characteristics: The quantity of air that passes through the cartridge determines how much contamination the cartridge is subjected to. In heavy work, more air per minute is used than in light work. There are great individual differences, and people who carry out the same work in the same environment can exhibit great differences in air consumption."
The SR 510 P100/HE particulate filter is a so-called mechanical filter. Broadly speaking, mechanical filters work like a fine net; the particles are captured and the pure air passes through very small holes in the filter medium. The more particles are captured in the medium, the more effective is the filtering. This means that you should replace the filter when breathing resistance increases noticeably. The SR 510 P100/HE particulate filter has been tested against a particle size of 0.4 micron, which is considered to be the most difficult particle size to capture with a particle filter. Larger and smaller particles are more easily captured by the filter. The SR 510 P100/HE particulate filter captures all types of particles such as dust, smoke, vapour, spray, spores, bacteria and viruses.
No, it causes leakage between the mask and face and provides a large reduction in the protection. Use instead spectacle kit SR 341.
A full face mask has larger contacts surfaces on your face and a stronger head harness that holds the mask in place, thus reducing the risk of leakage between the mask and face.
Pre-filter captures coarse dust and particles, are changed frequently and extends the life of SR 510 P100/HE particulate filter
Silica dust inhalation may cause diseases such as ”silicosis”, which is an chronic lung disease. It may also take many years (10-30) before the disease is detected after being exposed to silica. The disease mainly affects people who work in construction, foundries, mining and quarries. Use respiratory protection unless the silica dust level can be kept below the limit 0.05 mg/m3. Respiratory protection should be at least a half mask respirator with P100/HE particulate filter that is effective against silica dust.
