DC3.1 Air Blast Door
The first explosion-proof door produced and certified in Poland
Air Blast Door
Donimet explosion-proof doors DC3.1 AB were created in response to the current situation in the world, constantly growing threats. This is the first solution of this type produced from start to finish in Poland.
They are characterized by a very solid internal structure, and the EXR2 class doors are additionally covered with explosion-proof armour on the entire surface from the side exposed to explosion. Our team of experienced engineers has created a unique solution to disperse the shock wave and reduce its destructive impact on the door structure.
The materials used as well as the construction of the leaves and the frame prevent the door from being torn out or opened in the second phase of an explosion as a result of the huge negative pressure generated. The durability of the product has been confirmed by independent tests carried out by the Institute of Precision Mechanics, certification of explosion-proof doors according to the PN-EN 13123-2:2004 standard.
