Claim:
An equipment fan, having a housing ( 100 ) which is adapted for use as a plug-in module for a piece of equipment ( 320 ), the housing defining a generally annular recess ( 110 ), in which a fan wheel and an electric motor serving to drive it ( 20 ) are located, wherein, during operation, air is transported by said fan wheel from an air inlet side of the housing ( 100 ) to an air outlet side, wherein a front side ( 102 ) and a back side ( 104 ) of the housing extend between the air inlet side and the air outlet side, and upon installation, the back side ( 104 ) is slid into the equipment ( 320 ) first, a first lateral boundary face ( 140 ) and a second lateral boundary face ( 150 ) of the housing ( 100 ) extend between the air inlet side and the air outlet side and between the front side ( 102 ) and the back side ( 104 ), further comprising a faceplate ( 180 ), formed of material which limits emission, from the housing, of electromagnetic radiation, provided on the front side ( 102 ) of the housing ( 100 ), said faceplate being formed with indentations ( 160 , 170 ); a first resiliently deflectable detent member ( 142 ) arranged at the first lateral boundary face ( 140 ); a first actuation member ( 144 ) which extends from the front side ( 102 ) of the housing ( 100 ) and is operable to actuate said first deflectable detent member ( 142 ), said first actuation member ( 144 ) extending into one ( 160 ) of said indentations in said faceplate; a second resiliently deflectable detent member ( 152 ) arranged at the second lateral boundary face ( 150 ); and a second actuation member ( 154 ) which extends from the front side ( 102 ) of the housing ( 100 ) and is operable to actuate said second deflectable detent member ( 152 ), said second actuation member extending into another one ( 170 ) of said indentations in said faceplate ( 180 ); said first and second actuation members ( 144 , 154 ) being arranged on the front side ( 102 ), with a spacing selected such that said actuation members ( 144 , 154 ; 300 ) can be simultaneously actuated using only one hand.
