Majorly installed in airport hangars, warehouses, manufacturing units, fitness centres, malls, cattle farms, recreational facilities, etc., these fans are supplied in two variants- 5 blade and 4 blade HVLS fans. These are also offered in many designs, each of which is given a special model number. The fans rotate at slow and steady speed to cool down the facilities.
