Changeover valve or automatic changeover valve for work that requires use of compressed air for breathing and where an interruption of the air supply could be life threatening. Changeover valve with one connection for air hose from compressed air line and one conn ection for air hose from compressed air apparatus. Primary source is the compressed air line and secondary source is the compressed air apparatus that functions as a backup if the supply from the air line is cut off. When the device is switched from the primary to the secondary source, a whistle sounds. For use with BD Mini, DB 96 and Airmaxx compressed air systems.
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.
