Abstract

PURPOSE:To check any sticking of a pollutant onto a fan surface as well as to keep off the propagation of mold with the stiking of a large quantity of the pollutant by constituting a plastic blast fan with plural numbers of blade parts, and forming this constituent plastic material with highly slidable resin. CONSTITUTION:Highly slidable resin 5 is used for a constituent plastic material of a blade part 4 in a cross flow fan 1. This highly slidable resin 5 uses such one that mixes a glass fiber of about 30% in a styrene-based copolymer, by way of example. Consequently, even if dust, dirt or the like and a pollutant as serving as a nutritive source for mold are floated in the air as in the past, any sticking of the pollutant is checked and the propagation of mold with the sticking of a large quantity of the pollutant is kept back because a friction factor of the resin 5 is small and slidability of the surface is high enough. With this constitution, such problems that the pollutant, a spore of the mold and a colony of fungi, etc., are scattered out of an air conditioner are all ameliorable.
