Frequently Asked HVLS Questions
 
 
1. What is Tubercle Technology™?
  The Tubercle Technology™ is a sustainable power breakthrough which will allow a new generation of turbines, compressors, pumps and fans to deliver previously impossible levels of performance.
 
2. How does this technology differ from traditional air foils?
  The bottom line is this: Tubercle Technology™ blades out-perform all conventional air foils. No other blade can deliver stall angles as high as 22 degrees. No other blade always stalls gradually. No other blade can eliminate span-wise pumping (the primary cause of efficiency loss in all rotating systems). No other blade can eliminate tip stalling (the primary cause of blade noise and damaging vibration).
 
3. How does the Tubercle Technology™ effect the fan design and performance?
  The blades dramatically increase the efficiency and stability of our units. Five blades can do the work of ten, noise is less than 1/5 of conventional fans and they consume 20% less power.
 
4. What kind of maintenance do the fans require?
  Depending on the environment, the blades should be cleaned once or twice a year. It is recommended that, once a year mechanical connections be checked for proper tension. This also includes electrical connections in the fan controller and motor. It is recommended the oil level in the gear reducer should be checked once a year. In most cases the level should be within tolerances level but this is dependent on heat levels and time of operation.
 
5. Does the fan create negative or positive pressure in a structure?
  The fan does not create negative or positive pressure as it only moves air.
 
6. Who will install HVLS Fans?
  In most cases the customer prefers to install their own fan; however an installer can be recommended.
 
7. What is the warranty?
  Lifetime warranty on the blades and hub, limited 3 year warranty on the gear reducer, motor and fan controller.
 
8. What is the cost to operate an HVLS Fan?
  Pennies per hour.
