## Questions & Answers

**Q: What is air watt?**
A: Air watt is the way vacuum power is measured.  Following is the definition:An engineering unit used to express the effective cleaning power of a vacuum cleaner or central vacuum system. The air watt is practically the same as the ordinary watt. Measurements of vacuum power, however, are computed from English units using the following formula established by the American Society for Testing and Materials (ASTM): power in air watts equals 8.5·F·S, where F is the air flow in the system in cubic feet per minute (CFM) and S is the suction pressure in inches of water column (in WC). This definition makes the air watt equal to 0.9992 watt.

**Q: What’s the difference between the vacumaid sr14 and the vacumaid s2400?**
A: The SR14 is an permanent inverted bag filtered vacuum.  The S2400 is a cyclonic non filtered vacuum.
