The invisible curtain of this product is formed by the strong current which can effectively
cut off the outdoor toxic gas, dust, winged insects and the hot wave
in summer and cold wave in winter, so as to maintain the temperature and humidity
needed indoor.

Remote-controlled air curtain possesses simultaneously two different functions, remote
control and manual control, and at the same time it provides you three choices,
i.e. cold wind, warm wind and three-bracket timing. The pyrotoxin used in
cool-warm air curtain adopts two different types of hearting components, electric
heating pipe and new PTRC semi-conductor ceramic. The latter acquires such attributes
as quick heating, high efficiency in electricity-heat transformation. In
addition, it also has no visible fire and zero-depletion of oxygen. It's durable
and secure. In summer, without heating, it will be a standard air curtain, befit
both in summer and winter.
