Optrel Swiss Air TH3P R SL Particle Filter with Prefilter
The Optrel Swiss Air HEPA filter cartridge and pre-filter are designed for use with the Swiss Air (Powered Air Purifying Respirator) PAPR. These TH3P R SL particulate filters removes 99.8% of welding fume particulates, dust, smoke and aerosol. The pre-filter should always be fitted in front of the main filter, this ensures the larger particulates are removed first and drastically extends the life of the Swiss Air main filter.
The Swiss Air main filters should never be used without the filter seal, the seal must also be covered by its lubricant
Reliably protects against smoke, aerosols and dust
