Air convection outlets

Non-forced internal air devices, featuring an ad hoc installation, which prevents the entrance of
flammable liquids and, therefore, the outflow of preserved goods.

To assure a natural non-forced air convection to the reinforced concrete safety vaults, Parma Antonio & Figli implements air outlets with a special construction, called “goose-neck”. These devices have been conceived so to assure total security of the safety vault, since their shape assures that liquid (flammable) substances cannot penetrate from outside to inside the safety vault, and vice versa, and that valuables and preserved goods cannot flow out.

. On the outside, the air outlets feature a heavy duty plate, with 5 or 8 shaped holes to impede the passage of paper, coin or other material.

For correct installation, the air outlets are installed in pairs (1+1);
they are built for any type of wall width.
Natural air convection:

  • A pair of outlets with 5 pipes, allowing air changes in one hour in a premise, measuring 25 cubic meters
  • A pair of outlets with 8 pipes, allowing air changes in one hour in a premise, measuring 40 cubic meters.
