Abstract: Described herein is an industrial fan or blower including a flame-retardant polyamide composition.

Abstract: A recycling water feature for creating a vortex and a spillover visual effect includes a base with a reservoir. A tank is supported by the base which has a cylindrical shape. When a pump fluidly connected to the reservoir is activated, water from the reservoir is ejected through a fitting along a sidewall of the tank to create a partially formed vortex while filling the tank, cause an overflow portion to spill over an open top of the tank and drain through a plurality of apertures into the reservoir, and create a fully formed vortex having a depression which extends from the open top to a drain hole at a center portion of the tank with a remaining portion of the water for drainage into said reservoir.

Abstract: A fountain for creating a vortex includes a base housing with a lower reservoir therein. A pump moves water from the lower reservoir into a cylindrical upper tank located on a support platform. Tubing connects the pump to an elbow fitting, which extends through an inflow hole in the support platform. The elbow fitting ejects water into the tank along the sidewall immediately adjacent to said elbow fitting so as to fill the tank with water and create the vortex. Water eventually drains through a drain hole in the center of the support platform and returns to the lower reservoir.
