BS&B – Explosion Vents & Panels

Explosion Venting Protection for Equipment, Ducts and Buildings

An explosion can result from an ignition of a combustible gas, mist or dust when mixed with air during processing, handling or storage operations. A rapid rise in pressure occurs in the containing structure, and if it is not of adequate strength to withstand the deflagration pressure, extensive damage and injury to personnel can occur.

Explosion vents are low burst pressure membranes of calculated area fixed over an opening on the structure to be protected. In the event of a deflagration the vents provide a rapid and unrestricted opening at a predetermined burst pressure (Pstat) allowing combustion gases to expand and flow through the open vent. The required relief area necessary to protect plant or equipment may be determined by using the most current standards of NFPA 68 – 2018 or VDI 3673 – 2002.

The Vent-Saf® explosion vents can protect industrial equipment including silos, dust collectors, cyclones, conveyers, dryers…and many more.

• Types VSP™ (Vent-Saf Plus) and VSS™ (Vent-Saf Sanitary) domed single section metal explosion vents with integral gaskets. The dome is formed to resist vacuum.
• Type VSE™ (Vent-Saf Economy) a flat, single section metal explosion vent with integral gaskets.
• Type EXP/DV™ a round domed explosion vent of composite construction with integral gaskets. The EXP/DV vent has a laser cut stitch pattern in the dome area. A Teflon® liner covers the slits providing a seal. The vent burst pressure is controlled by the arrangement of the stitch pattern.
• Type EXP/LCV vent is a rectangular flat vent of composite construction laser cut in a stitch pattern around the vent’s perimeter.

The Vent-Saf vents are available in both round or rectangular styles designed to be mounted on the structure to be protected using a Safety Frame.

• Unique, economic and patented design.
• Accurate reliable and leak tight.
• Enhanced abrasion resistance.
• One-piece metal construction without slits on the process side avoiding product accumulation.
• Optional design for aseptic/sanitary applications.
• No fragile PTFE seal that may puncture and admit moisture.
• Superior dynamic performance due to low mass compared with composite designs.
• Operating pressures up to 60% of the minimum tagged pressure rating (80% under certain conditions).
• Thermal insulation available to permit use in operating temperatures to 2000°F/1093°C, to reduce heat loss or prevent condensation.
• Supplied with integral gaskets ready for installation.
• Fail-safe design, if damaged it will provide a relief opening below its rated pressure.
