Continental's vent panels are designed to allow a full and immediate opening to minimize structural or mechanical damage that may be caused by expanding gases. These gas expansions can result from the deflagration** of dust, gases, or mists in equipment, rooms, buildings, or other enclosures. Continental's vent panels provide the following benefits: Full, instantaneous opening Օ Full opening under dynamic or static pressure conditions Designs interchangeable with existing panel applications Օ Available with Continental's patented Burst Disc Indicator (B.D.I.®) Alarm Strip Designs available for non-fragmentation Continental's vent panels are offered in rectangular, square, or circular configurations and in several types of construction to meet the operating parameters of various applications. The VP series vent panel is a flat, scored, and epoxy coated aluminum panel. This panel is best suited for operating conditions of positive pressure or vacuum pulsations. It is recommended for a maximum 50% operating to burst pressure ratio, positive or negative. The CP series vent panel is a flat composite style panel constructed of 316SS and Teflon. This panel is ideally suited for cyclic operating conditions, going from positive to negative or negative to positive pressures. A 50% maximum operating to burst pressure ratio is recommended. The SFC solid metal, and CFC composite (metal/Teflon) vent panels are prebulged, circular designs. These panels are suitable for higher operating conditions of up to 70% of the burst rating positive pressure and negative pressure of up to 14.7 psig (1.02 barg) full vacuum. **Deflagration as defined under NFPA-68 is: "Burning which takes place at a flame speed below the velocity of sound in the unburned media." Vent panels are not generally suitable for protection against pressure or shock waves produced from detonation of dust, gases, mists, or explosives. Detonation as defined by NFPA-68 is: "Burning which takes place at a flame speed above the velocity of sound in the unburned media." *United States patent no.'s 4,498,261; 4,612,739.

The VP series vent panel is a flat,scored aluminum panel with epoxy coating applied to the process and vent sides. It is available in square (VPS), rectangular (VPR) or circular (VPC) configuration. Burst pressures range from a minimum of 1.0 psig (0,07 barg) to a maximum of 5.0 psig (0,35 barg).VP series vent panels are designedto operate under conditions of positive or vacuum pressure of up to 50% of the vent panels minimum burst rating. These economical vent panels are designed to provide protection under low pressure static conditions and may be used for positive pressure or vacuum...

The CP series vent panel is a flat,composite panel usually constructed of a 316SS top section, TFE Teflon > * seal, and316SS support section. The composite vent panel is available in rectangular (CPR), square (CPS), or circular (CPC) configuration. Burst pressures range from a minimum of 1.5 psig (0,10 barg) to a maximum of 10 psig (0,69 barg).The CP series vent panel is designedto operate under conditions of positive or vacuum pressure to 50% of the vent panelΒs minimum burst rating. This design is excellent for applications operating under cyclic, positive to negative pressures; low burst...

The SFC and CFC vent panelsare prebulged, circular vent panels utilizing a solid metal or a metal/Teflon construction. The SFC vent panel is available in sizes 10" through 36" (25 cm through 91 cm) diameter. The CFC vent panel ranges in size from 10" through 30" (25 cm through 76 cm) diameter. Both panels are available in burst pressures ranging from 2.0 psig (0,14 barg) to 10 psig (0,69 barg), depending on the type vent panel.SFC and CFC vent panels aredesigned to operate under conditions of positive pressure up to 70% of the vent panels minimum burst rating and under vacuum conditions of...

Gaskets Coating Square and Rectangular Framing > Gaskets are available for allvent panel configurations. Materials include Black Neoprene, Silicone Rubber, and Fiberglass rope. Gaskets are key lockedӔ together at the corners to assure a leak-tight seal (except on fiberglass). See table below for temperature limitations. As a standard, an epoxycoating is applied to both sides of the aluminum VP Series vent panels. To order a VP or VPC style vent panel without this coating, please specify No Epoxy CoatingӔ at the time of order. Vent panel framing for square and rectangularconfigurations is...

Proper vent panel selection isa function of several requirements including, vent area, burst pressure, operating pressure and operating vacuum (if expected), operating pressure cycles, and atmospheric and media exposure.National Fire Protection Associate.standard NFPA-68, Explosion Venting,Ӕ is a source of the vital information fordetermining vent area requirements, vent location, and critical factors for designing a structure or piece of equipment that will withstand a gas, dust, or mist deflagration. Vent area calculations depend upon such characteristics as rate of pressure rise, maximum...
