1 Water only at the base of the plant and early in the day. Long periods of moisture on foliage encourage blight.  Use a tomato staking system and remove suckers to increase air movement through the plant and to reduce moisture on the foliage. Staking also improves fruit quality and helps prevent root rot.
Expert: Ivan replied 6 years ago. The Blower Control Module is the responsible component. It looks like a flat plate the is bolted to top of the housing that the blower motor is located in. It has 2 plugs that plug into it. That is the entire controlling aspect of the blower operation with an automatic climate control system. There are no other relays.
Industrial fan. Industrial fans and blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine. The flow rates of these mechanical fans range from approximately 200 cubic feet to 2,000,000 cubic feet per minute. A blower is another name for a fan that operates where the resistance to the flow is primarily on the downstream side of the fan.
