The Swiss Air positive pressure ventilated half mask is manufactured from a hard wearing flame-retardant material. It's designed to completely encapsulate the mouth and nose area, with an adjustable face seal which enables the mask to maintain the positive pressure. This negates the need for fit testing and can be worn for up to 8 hours without the need for the wearer to take a break. Sufficient air is always available in every breathing state and there is no breathing resistance to overcome. This also helps to support the wearers breathing and helps to massively reduce wearer fatigue.
Manufactured from flame-retardant, Ripstop fabric which uses a special reinforcing technique making the fabric highly resistant to tearing and ripping.
Issuing individuals with their own replacement mouth and nose mask makes it possible for the main blower unit system to be shared among multiple users.
The inlay is manufactured from a soft and flexible Polyurethane foam.
Exchangeable soft nose foam.
Exhalation valve with silicone membrane which helps expel any excess moisture.
Particles will not penetrate through the half mask.
Reusable mask, washable up to max. 90°C
