Greenheck - HBS Series Blast Damper Testing

As building codes and safety standards evolve, blast protection within ventilation systems is becoming more critical. Building codes, such as Unified Facilities Criteria (UFC) and General Services Administration (GSA), specify blast rating requirements.
Greenheck offers blast protection solutions with our HBS series dampers. These dampers can be used in both intake and exhaust applications and in multiple mounting orientations.
Greenheck’s design and mounting options were verified with FEA simulation. Offering several different installation options allows for flexibility in the building HVAC design.
The final product was then subjected to actual blast testing at a third party independent test lab to prove its design. After the blast pressures subside, the damper re-opens to allow for normal ventilation.
By stopping the blast wave from traveling through a system, equipment and ductwork downstream will sustain much less damage. Greenheck’s design offers low pressure drop performance which translates into lower energy use during building operations.
Greenheck will continue to lead the industry in new and innovative damper products and solutions.

Also one other thing you left out - why would I opt for a damper instead of a blast valve? A damper mitigates some damage, a blast valve stops the damage entirely, and a pressure capable ducting system pre blast valve means zero duct damage and perfect operability post-incident. So one system seems to knock you down for a few days and does mitigated damage, the other means no down time and no damage. What's the point in a damper?

Designers have many options when it comes to blast protection. There are many different facets to be considered when selecting the best option, including the size of the potential blast, the likelihood of the blast, the initial cost of the protection, cost of downtime, the type or location of the building that needs protected, the anticipated distance from the blast to the area needing protection, etc. When weighing all of those options, some solutions will inevitably be more cost effective than others and some solutions will be more protective than others. It's the designers and owners responsibility to weigh those options against the risks associated with them.

What 'third party independent test lab'? I'm always suspicious when the name of a testing facility isn't mentioned, it usually makes me presume it's one of those dodgy Chinese companies.
