Connector unit for a fan

A connector unit formed out of a side piece of a blower housing and an engine mounting plate for a drive motor of a blower, whereby the engine mounting plate is attachable to the side piece in various rotational or alternatively angular positions vis-à-vis a rotational axis that runs in an axial direction to the side piece, wherein the connector unit is formed in two pieces comprising the engine mounting plate and the side piece which are connected in a gas-tight manner, and

• wherein an angular rotation of the engine mounting plate with respect to the side piece for the determination of the various rotational or alternatively angular positions of the mounting plate is infinitely variable on the side piece;
• wherein the engine mounting plate features at least one motor support;
• wherein the engine mounting plate features a ring element, from which each of the motor supports integrally extends away in a radial and axial direction;
• and
• and wherein the motor supports each comprise a laterally insertion opening.
