A low pressure venting panel acts to safely vent a pressure vessel, such as a bag house, from overpressure conditions. The venting panel is particularly responsive and predictable at low pressures. The panel includes a thin rupture body with a central group of apertures and slit lines emanating from the apertures. A thin sealing membrane is bonded to one surface of the rupture body at least in the area of the slits. The characteristics of the sealing membrane enable the membrane to resist expansion in the area of the slits when pressure is applied to the rupture body, thereby resisting rupture of the membrane up to the design rupture limit of the venting panel.

A low pressure venting panel comprising: (a) a rupture body having a central portion and a peripheral margin; (b) said rupture body having a plurality of slits in said central portion, said slits emanating from an area substantially proximate a center of said rupture body toward said peripheral margin so as to define a plurality of leaves such that said leaves are spreadable outward upon rupture of said rupture body toward said peripheral margin so as to define a plurality of leaves such that said leaves are spreadable outward upon rupture of said rupture body; (c) a bonding agent on a first side of said rupture body; and (d) a sealing membrane abutting said first side of said rupture body such that said rupture body and said sealing membrane are securely bonded to each other by said bonding agent at least on both sides of said slits and substantially adjacent thereto; and said sealing membrane being a semi-elastic material and being substantially resistant to expansion in the area of said slits.
