Overview
The Optrel Swiss Air Loose Fit Half Mask is the one-size loose-fitting breathing interface for the Swiss Air PAPR system. It is designed to create a positive-pressure breathing zone without relying on a tight face seal.
Key details

- SizeOne size
- Fit testingNo formal tight-face fit test required

The loose-fit design allows the Swiss Air system to be worn under compatible welding helmets and face protection without sealing tightly to the wearer's face.
What else do I need?
This product is the half mask only. It must be connected to the Optrel Swiss Air PAPR blower system and is not compatible with the e3000X PAPR.
Protection
Optrel lists the Swiss Air loose-fit configuration as TH3 and reports a protection factor of 500. That protection belongs to the complete Swiss Air configuration, not to the half mask on its own.
