For blast resistant products, there are various design philosophies available as options to manufacturers. Some are easy and some are very tough. It is difficult to

tell which one is good and which one is not because the applications could vary significantly. However it is necessary for designers and users to seriously consider

all design facts related to blast resistant products in order to assure the right products are placed at right positions regarding both safety and cost. Here are some

examples of design philosophies of blast dampers for reference.

Design philosophy Options	How it works?
Finish fast!	In this case the blast dampers are expected to stand the blast waves with duration of only a few milliseconds. The blast load will mostly attenuate to zero before the dampers’ closing. Hence the damper structure won’t take pressure load.   To provide the blast protection, the blast attenuators are necessary to work with blast dampers.
Let it go!	In this case the blast dampers are expected to stand the blast waves which could be high level overpressure and long duration. The working position of blades of these blast dampers could be placed at approximate horizontal, so the blast dampers could let the blast waves go through without taking blast load.   To provide the blast protection, the blast attenuators are necessary to work with blast dampers.
Provide heavy shield!	In this case the blast dampers shall be able to take the blast loads even after its closing so they have to be very strong. In some practices the blades could be very thick in order to take long lasting blast waves but its closing speed is also low due to high mass, so passing through blast waves could be a big issue if it is a concern.   To provide the blast protection, the blast attenuators are necessary to work with blast dampers.
Care protection!  Strong + Light + Response fast	In this case blast dampers shall not only be able to stand high pressure blast waves with long duration, but also close very fast to block the blast waves penetrating inside. The impulse block rate of FUCARE rapid blast dampers is more than 98% in actual tests. By achieving all these, FUCARE blast dampers can offer the best protection for applications.   No blast attenuators are required.

FUCARE positions its products as high performance protection solutions for those customers who not only require the blast resistance but also

require the blast dampers to provide protection against blast waves, so it constantly takes the tough challenges in developing the product solutions.
