System Overview<\/span><\/h2>\r\n
\r\n

Fresh Air Valve With Thermostat is an energy-efficient passive ventilation solution for continuous fresh air in residential and small commercial spaces.<\/p>\r\n

The valve automatically adjusts its opening based on outdoor temperature, helping provide fresh air while minimizing energy loss during colder conditions.<\/p>\r\n<\/div>\r\n<\/section>\r\n

\r\n

Core Engineering Features<\/span><\/h2>\r\n

Designed for simple room ventilation, this thermostatic fresh-air valve combines automatic temperature response, passive operation and practical manual control.<\/p>\r\n

\r\n
\r\n
THERMOSTAT<\/div>\r\n

Mechanical Temperature Control<\/h3>\r\n

A built-in mechanical thermostat adjusts the valve opening according to outdoor temperature without electrical connection.<\/p>\r\n<\/div>\r\n

\r\n
PASSIVE FLOW<\/div>\r\n

Continuous Fresh Air Supply<\/h3>\r\n

The valve supports room-scale fresh-air intake for homes, offices and other spaces that need passive ventilation.<\/p>\r\n<\/div>\r\n

\r\n
AUTO OPEN<\/div>\r\n

Opens Above +10\u00b0C<\/h3>\r\n

When outdoor temperature is above +10\u00b0C, the valve fully opens to increase fresh-air supply.<\/p>\r\n<\/div>\r\n

\r\n
AUTO CLOSE<\/div>\r\n

Closes Below -5\u00b0C<\/h3>\r\n

When outdoor temperature drops below -5\u00b0C, the valve closes to help reduce cold-air entry and energy loss.<\/p>\r\n<\/div>\r\n

\r\n
NO POWER<\/div>\r\n

No Wiring Required<\/h3>\r\n

Operation is based on thermal expansion of the thermostat element, so no wiring or power supply is required.<\/p>\r\n<\/div>\r\n

\r\n
MANUAL MODE<\/div>\r\n

Manual Closing Option<\/h3>\r\n

The valve can also be manually closed when the user needs temporary air shutoff.<\/p>\r\n<\/div>\r\n<\/div>\r\n<\/section>\r\n

Operation Notes<\/span><\/h2>\r\n
\r\n

Automatic thermostat control:<\/strong> The valve fully opens when outdoor temperature is above +10\u00b0C and fully closes when the temperature drops below -5\u00b0C.<\/p>\r\n

Mechanical operation:<\/strong> The valve operates based on thermal expansion of the thermostat element, with no wiring or power supply required.<\/p>\r\n

Manual closure:<\/strong> The product can also be manually closed when the room does not require fresh-air intake.<\/p>\r\n

Application range:<\/strong> Suitable for apartments, residential homes, offices, meeting rooms, bathrooms, kitchens, utility spaces, storage rooms and similar passive ventilation environments.<\/p>\r\n<\/div>\r\n<\/section>\r\n
