Abstract: The present invention discloses a high flow low pressure suction device. The device is a non-contact suction device based on multiple stage turbulence based low pressure suction mechanism which comprises fan(s) or rotating impeller(s) for drawing air/fluid/slurries operates without any seal between the device and the sucked surface. The device compounds this turbulence based low pressure generation along with Bernoulli's principle to yield a high efficiency suction device. The device implements the above concept by making the air/fluid/slurries flow through two or three zones selected from the acceleration zone(s), turbulence zone(s) (high turbulence zone) and smooth zone(s) (minimum turbulence zone).
