VISCO, is Santem’s own product and its brand new design. Its prefilter is designed in large sizes and can be easily cleaned. Santem Visco’s design consists of high flow, high pressure and low decibel levels which operates with a motor that consumes efficient energy with low operation cost. It also has a lock-nut feature to prevent the fan from breaking down in case electrical wires are connected incorrectly, causing the fan to rotate counterclockwise. Santem uses Turkey’s number one motor – the WAT electric motors.
