: • : Replaces valves for Techno™ City™ & Nitesight™ Masks
: • : Medical grade silicon rubber diaphragms
: • : Interchangeable with all masks
: • : Releases heat, water vapour and CO2 out of the mask
The Techno™ valve is robust and is perfect for town use. However it does not have the same characteristics as the Powa™ valve when it comes to higher breathing rates associated with physical exertion.
: • : Comes stock on the Sportsta™ Mask
: • : Interchangeable on nearly all masks and filters
: • : Highest airflow for aerobic activity
The Powa™ Valve Pack contains 2 Powa™ Valves that can be used in the majority of Respro Masks (with the exception of the Metro™ Mask). These Valves have better breathing characteristics at higher airflows, i.e. when breathing heavily in sports or when engaged in strenuous physical exertion.
You can use Powa™ Valves with Techno™ Filters or vice-versa. The Sportsta™ Filter gives better inhalation characteristics over the City™ Filter and the Techno™ Filter.
This combined with Powa™ Valves is why the Sportsta™ Mask is perfect for use in sports activities.
