I'm sorry but I couldn't find any reference to such name on
http://www.aosong.com/en/
In the contact page (http://www.aosong.com/en/article-34.html),
I could only find references to "Guangzhou Aosong Electronic Co., Ltd."

Asair is the brand name under which Guangzhou Aosong Electronics sells
their products [0]. After a prior discussion with Krzysztof [1], I
thought it would be the best to go with Aosong instead.

The rationale being since a vendor can only have a single prefix, if
Aosong were to sell some new product under the name Aosong, it would
then have to have the same vendor-prefix as other products under the
Asair brand.
