VSB™ Building Explosion Vents
ＶＳＢ建築ベント ビル/建築保護用低圧爆発ベント
Description
Individual Type VSB vents can be made to fit the available building apertures that achieve the required vent area for deflagration venting. Type VSB vents are available in sizes up to 56” x 120” (1.2m x 3m) and with set pressures as low as 4” Water Column / 0.14psi (10mBar).
Construction
- Polycarbonate or Aluminium sheet
- Aluminium perimeter frame
- Dual seal from frame to vent
- Centrally mounted “burst tab” to control set pressure
- Dynamic release cord that retains vent after activation
Polycarbonate vent construction permits transmission of daylight while maintaining insulation properties similar to double pane glass (typical R value of 2.7) and an impact strength rating of over 200 times that of single pane glass.
