silicone mask
Designed for three head sizes, suitable for 99.97% of human face contours
air intake module
The built-in air inlet valve of the silicone mask prevents moisture in each exhalation from entering the main filter element, thereby preventing the reduction of filtration efficiency and increasing in breathing resistance caused by moisture, thus extending the life of the filter.

Best-in-class battery life with battery replaceable
Up to 16 hours of battery run time
Best-In-Class wearability for doing tough jobs
A sophisticated computational fluid dynamics design tool in conjunction with a novel motor design brings about a patented streamlined blower with powerful flow generation.

The patented structure spreads the main unit around the head, with the blower fitted inside a flexible pipe loaded at the back of the neck, ensuring easy head movement while doing physically demanding jobs.
Best-In-Class Protection and Lowest In-class Costs
The filter element must connect to the Power Unit inlet in order to work, thus it is not possible to have the system connected without the filter element properly fitted – A fool-proof and intrinsically safe design.
The silicone masks come in 3 sizes and are specially designed for 3 representative human head models, achieving an adaptive soft cushion that closely matches the facial profile of up to 99.7% of human demographics, resulting in a superb fit to cover most human faces, thus providing more reliable protection and comfort.

High-performance Injection Moulding Equipment
Automated and Intelligent Assembly Process
Advanced manufacturing techniques bring about low-cost quality products.
Based on nearly 25 years of design and manufacturing experience for respiratory products, ranging from medical, industrial, and consumer applications, we have an in-depth understanding of the common and specific requirements for each market. This expertise allows us to stand on a higher ground than most players in the market, which brings about a novel concept for our breathing training device that provides a holistic solution to train you toward optimal breathing.
To facilitate the modular structure, we invented a Push-fit & Twist-release connection that is included in each module, so that different modules can be connected and disconnected quickly and conveniently.
