Protection Grid TRA 350 for Wall Fans
The Protection Grid TRA 350 is an ideal solution for outdoor mounting for wall fans from the EQ, MP, E, and CA-W series. It provides effective protection against access to the impeller while meeting the requirements of DIN 31001. This grid is specifically designed for the nominal width 350 and ensures safe installation on the exterior wall.
The similarities between the TRA 250 and TRA 350 variants lie in their construction and material. Both grids are made of galvanized steel sheet and feature a hammer-gray powder coating that protects against weather influences. Installation is straightforward with four drill holes, ensuring secure fastening. The main difference lies in the nominal width, which is tailored for different fan sizes.
The decision to choose the Protection Grid TRA 350 should be made when using a wall fan with the corresponding nominal width. For smaller fans, we recommend the Protection Grid TRA 250.
