Centerline velocity equation for the circular slot hood was thus constructed to design the local exhaust system. Recommended values for airflow rate into the circular slot hood and the average slot face velocity were found to be 20.14 m3/min and 8.55 m/sec, respectively. The optimum air velocity at a. Always check local regulations before design. Capture velocity - v 1 - for an exhaust hood can be estimated with the empirical equation. V 1 = q / 2 y 2 c (1) where. V 1 = capturing velocity (m/s) q = air volume flow (m 3 /s) y = distance between table and exhaust hood (m) c = circumference of the hood (m).

ATMOS360’S Close Capture dust hoods with pneumatic cylinder actuated stripping baffles demonstrate superior performance in papermaking and converting applications. In area where close capture hoods are not feasible (an unsupported web or spatial constraints) we utilize general Area exhaust hoods. This combination of close capture and area hoods are used successfully on weak sheets such as facial and tissue lines. They provide optimum dust collection performance that result in improved process reliability.

You’ll appreciate the solid construction and durable welded joints of our galvanized steel, stainless steel, aluminum and thermoplastic industrial ventilation hoods, each built to a specific size. A wide range of styles meets virtually any exhaust application—from vehicle maintenance to wastewater treatment to manufacturing. Single-piece construction is available up to any size that will fit on a truck and larger sizes are available in multiple sections for field assembly.
