What Type of Maintenance Does an Air Curtain Require?
NONE: (Note: With a special unit where belt drives are used the belts should be checked every 2-5 years, depending on the number of starts that the unit has to do. In normal applications the fans are self cleaning and should not require any maintenance for at least 10 years. The exception is the belt drives. For severe use these may have to be re-greased every 2-10 years. (More bearings are damaged from over greasing than not enough!) If we supply the magnetic starters, these are of a long life with energy efficient coils, these may require new contact points after some 100,000 operations. In normal life, with some 1000 starts per year, this means a practically indefinite life.
