Blowers
Chemical and electrochemical actions significantly reduce the service life of industrial fans as well as industrial blowers. The concentrations of air streams, their temperature, and the extent of moisture they contain determine the level of corrosion that takes place. Primary corrosives include but are not limited to salts, alkali, acids, etc. Here are some types of coatings that are effective at protecting industrial fans and industrial blowers from corrosion:
Polyester Powder Coating:
Coating industrial fans with TGIC powder enables them to become heavily fortified at their exterior for extreme durability. The coating protects the fans and blowers from mineral acids, salts, and humidity. The paint quality uniformly covers the surface and is economical as well as long-lasting. Polyester powder industrial fan coatings are hard films that can resist temperatures of up to 200° F.
Enamel Coatings
Rated for up to 300° F. enamel is ideal for waterproofing and high and volatile temperature applications. You can use enamel coatings that are latex-based, water-based, and oil-based. These industrial fan coatings are highly protective in the general industrial environment. They have great gloss and color retention and quick dry times.
Zinc-Rich Organic Coatings
Hot-dipped galvanizing of big industrial fans and blowers is neither practical nor effective. On the contrary, spraying a coating of cold zinc is highly corrosion resistant and protective against high impacts. Using it as a base coat protects the steel of the industrial blowers and fans even if the exterior coating gets damaged, exposing the inner surfaces. Zinc naturally has a lower electrochemical potential than steel. Therefore, it is actively held in a neutral state. It is ideal for carbon steel fans that operate at temperatures between 275° F and 750° F.
Epoxy Coatings
Epoxy coatings have a longer service life than other conventional coatings against caustic solvent and the mild acid it produces. They are sturdy as phenolic and show great chemical resistance to fume, spillage, and splash. They are resin-based and offer a finish that protects against alkali, acids, salts, and water as well. However, their drying time is long, and they are not ideal for ultraviolet radiation. They have a temperature limitation of 200° F to 300° F.
Polyurethane Coatings
Usually applied over epoxy primers, zinc, steel, and aluminum surfaces, polyurethane is efficient at resisting abrasion, impact, alkalis, acids, ultraviolet degradation, weathering, and chemicals. They can be cured by catalyzing and air-drying and offer a high-gloss and hard–yet-flexible finish.
Heresite Coatings
Heresite industrial fan coatings are the most effective at tackling explosive gases and dust. It is ideal for demanding industrial settings and harsh airstreams and environments. It is a high-performance epoxy-silane that is formulated for direct metal application. It also protects against UV rays, weathering, corrosion, and ferrous as well as non-ferrous metals. They do not require primers or pre-treatment.
