The SR 900 half mask is made of thermoplastic elastomer (TPE) and polypropylene (PP) in three sizes, S, M and L. The mask is equipped with two exhalation valves, which ensures very low exhalation resistance. The valve covers with partitions effectively protect the exhalation membrane against dust and paint mist. The material and pigment of the mask body are approved by FDA for foods, which minimizes the risk of contact allergies. The easily adjustable elastic head harness straps of the mask are designed as a V-shaped loop and have a large dished crown plate, which contributes towards a comfortable and safe fit. The half mask SR 900 is used in combination with: • Filters from the Sundström range. • Remote filter holder SR 905 according EN 12083. • The SR 307 or SR 507 compressed air attachmnet which then serves as a breathing apparatus with continuous flow for connection to a compressed air supply according EN 14594:2005. • The fan unit SR 500/SR 700 and approved filters included in the Sundström fanassisted respiratory protective device s ystem conforming to EN 12942:1998. A pre-filter holder is supplied. Best stored in box SR 230 or storage case SR 339.
Gases, toxic fumes, oxygen deficiency, dust particles, and mists are not always immediately detectable, although they can be life-threatening. Therefore, it is very important to get advice from an expert when you suspect that there may be a risk to the respiratory tract.
This risk, together with the work to be carried out, will determine whether you can work with environment-dependent respiratory protection such as dust masks or half and full-face masks, motor units, etc.
When it is not possible to filter the air present, it is better to opt for environmental-independent breathing protection. These can be air caps or masks that are connected to the compressed air network. When you need to be sufficiently mobile, it is better to opt for a self-contained system such as a compressed air device or an escape mask.
It is also important to know in advance which substance to ‘filter out’ and how much of it.
If that is the case, calculate the Nominal Protection Factor (NPF) and use it to select the right mask with filter. Don’t know which it is in advance? Then you’ll need to opt for the ‘ABEK’ filters.
You will find all leading brands in our range: MSA, 3M, Moldex, Bartels, PureFlo, Honeywell, Genano, Scott, Avon, Spasciani, rsg safety, etc.
Did you find the right product? Then it’s important to check that it fits your face. We do this at Vandeputte by means of a Fit test.
Lastly, you can also contact us for the periodic maintenance of your respiratory protection: refilling compressed air bottles, cleaning and maintaining full-face masks, maintaining and repairing lung vents and breathing apparatus, etc.
