Although the 600 cfm, 700 cfm and 1

15

0 cfm models have good ef

ficiencies, the supply air could be colder than the ambient room 

air

. It

is possible to eliminate the discomfort associated with this temperature dif

ference by installing an electric duct heater

This

 will temper the

air before it is distributed throughout the building. 

The table below gives the heating requirements at dif

ferent temperatures 

and airflows.
