An air curtain is a product which creates a uniform stream of directed air, whether heated or unheated, across an opening to create a barrier inhibiting the transfer of heat and particulate matter from one zone to the other. An appropriately designed system will create this barrier across the entire height and width of the opening to create the effects. AIR CURTAINS are widely installed at the entrances of supermarket, theater, hotel, food storage warehouse, residentials. etc. We are into industrial equipment we delivered every way
