jukejoint Posted June 24, 2014 Share Posted June 24, 2014 If you have a electric blower and you use a rheostat is there still a need for a air gate? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted June 25, 2014 Share Posted June 25, 2014 Yes No or Maybe depending on factors you didn't mention. Quote Link to comment Share on other sites More sharing options...
rockstar.esq Posted June 25, 2014 Share Posted June 25, 2014 Air gates can be faster to adjust airflow. Sometimes a speed control causes a lag in the blower's action. If a fan is allowed to maintain it's speed, there are fewer peaks and valleys in it's performance. The air gate can be sprung and arranged like a deadmans switch to avoid wasting fuel.

Frosty Posted June 27, 2014 Share Posted June 27, 2014 An air gate will prevent potential damage to the blower motor, over heating the electric supply, blowing breakers or possibly starting a fire. Air adjustment is also instantly responsive. A rheostat is a motor killer unless the motor is really old school. Even if it works it adjusts the current by increasing the resistance and converting said current to heat. Unless the entire circuit is designed with a rheostat in mind there's nothing safe or good about them. Use an air gate. Lose the rheostat. Frosty The Lucky.

Dan C Posted June 27, 2014 Share Posted June 27, 2014 Or do something like this, stupidly simple but works very well. Post #4 is my setup. I don't use a rheostat but do have a Christmas tree footswitch to turn everything off & on.
