The present disclosure concerns a fastening strut for a fan guard with at least one first leg extending in a longitudinal direction, configured so as to reach across several cage bars of the fan guard, wherein the at least one first leg comprises a free lengthwise end, and in the region of the free lengthwise end of the at least one first leg a cube-shaped or cuboidal fastening element is secured laterally to the at least one first leg by integral bonding in a transverse direction running perpendicular to the longitudinal direction.

Fastening strut for a fan guard

A housing for a fan or blower, in particular an axial fan, includes a wall ring () having an inlet nozzle section (), an outer diffuser () having an inlet flow opening () and an outlet flow opening (), and a holder for an electric motor () of the fan. The holder is arranged in an inner space of the housing. The outer diffuser () is formed by at least two partial ring sections that are connected to the outer circumferential surface via mechanical connection elements. The holder includes several struts () that are fastened to an inner circumferential surface of the outer diffuser () by one end, are circumferentially spaced apart, and are fastened in the edge region of the inlet flow opening (). The struts can be installed by their other end to a motor flange () of the motor housing () of the electric motor ().

Housing for an axial fan

A diffuser () for a fan () of axial, radial or diagonal type of construction, has an inlet opening () and having an outlet opening () for a gaseous medium which flows through a diffuser interior (I), which is enclosed by an outer housing (), in an axially oriented main flow direction (S) from the inlet opening () to the outlet opening (). The cross section of the diffuser interior (I) increases from the cross section () of the inlet opening to the cross section () of the outlet opening (), wherein the outer housing () forms an outer diffuser part (AD) which delimits the diffuser interior (I) to the outside. Along the main flow direction (S), the cross section of the outer diffuser part (AD) changes from a circular cross section () at the inlet opening () to a non-circular cross section () at the outlet opening ().

The invention relates to a ventilator, having an electrical ventilator motor and an electrical connection device for connecting electrical motor lines leading to the motor to external electrical connecting lines. The connection device has a terminal box mounted to a device part comprising electrical contact elements, and has an additional connection part, to which the motor lines are connected. The terminal box is releasably connected to the additional connection part via electrical plug-in connections.

The invention relates to a wall ring for an axial fan comprised of a supporting frame () on which a circular connecting piece () is formed, inside which the axial fan is arranged. The supporting frame () is assembled from a plurality of frame elements () by means of form and force-fitting connecting elements. The circular connecting piece () is formed of a plurality of circular segments () arranged circumferentially one after the other, said circular segments being connected to each other and to the supporting frame () by means of form and force-fitting or material-bonded connections or by such connection elements, respectively.
