Explosion Vents (Vent-Saf)

Explosion Vents (Vent-Saf)

Performance Features

  • 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

In the event of a deflagration, Vent-Saf explosion 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 or VDI 3673. The most suitable explosion vent may be selected by matching the information in this catalog with the particular operating conditions.

BS&B explosion vents are available in both round or rectangle styles and are designed to protect industrial equipment including silos, dust collectors, cyclones, conveyers, dryers, etc.

For economy half silicone sponge gaskets are provided as standard which cover half the flange to the bolt holes. Full gaskets may be supplied on request. Alternative gasket materials including Neoprene and solid Viton® are also available.


Design/Application Gasket Seal
Standard designs** Silicone sponge Silicone sponge
Sanitary / aseptic design White solid silicone (FDA) RTV (FDA approved)
High temperature applications (above 300°F, 150°C) Solid silicone RTV (high temperature)

* Consult BS&B for alternative material options
** Silicone sponge component acts as a gasket / seal and is fitted to both sides of the vent
