Fan widely used in factories, mines, tunnels, cooling towers, vehicles, ships and building ventilation, cooling and dust exhaust and cooling, ventilation of boilers and industrial furnaces, and the wind, air-conditioning equipment and household appliances ventilation, grain drying and sending inflatable wind tunnel wind source and hovercraft propulsion. %% @ #% # @%%% @ # # @% The product attributes% @ # # @% ventilator Product Features: · Noise · air volume, high efficiency · · pastel wind pressure stable Guangyan enduring %% @ #% # @%% 3% @ # # @%% @ # # @% Uses: generate air convection row of cooling gas. Reduce the air conditioning load, increase indoor fresh air. Withdrawn roof moisture, Meiqi, steam, and keep the roof dry. Instead of a heavy-duty electric blower, the to reduce stent cost savings in electricity, minus the noise. %% @ #% # @%% 34% @ # # @% installation, maintenance% @ # # @% displacement installed in the windows above the large displacement installed on the roof (to set up more special transom)%% @ % @ # # @%,%% 7% @ # # @ #% # @% Notes through practice, the ventilation design of the plant must be noted: first, the creation of enough air into and out of the area; reasonable layout and out outlet position to be considered a regional problem of wind; reasonable arrangements of air into and out around the layout; fourth, when necessary, a reasonable increase in the mechanical blower / ventilation equipment ventilation requirements to meet the in-depth site. %% @ #% # @%% 12% @ # # @% description% @ # # @% plant ventilation equipment sub-air conditioning, fan, fan, etc.; including air conditioning central air conditioning. Environmentally friendly air-conditioning, hanging vertical air way to supply air ventilation, a cooling effect; fan, the fan at high, medium and low negative pressure air supply and exhaust ventilation pathways which negative pressure, mainly used for dust-free workshop, electronic packaging, office space, etc., fan with hydro wet curtain, can also play a cooling effect, is to reduce the temperature of the air through the water-cooling principle, the body feels more comfortable. % @ # # @%%% @ #% # @%% 14% @ # # @% transaction description, face-to-face transactions 2, online trading, auctions, Buy transaction%% @ #% # @%%
