Direct & Belt drive wall fans designed for heavy duty, commercial and industrial exhaust applications These fans are typically used for high volume, high static pressure applications. The series ADD is designed and constructed for efficient & economical operations and is direct drive, therefore requiring little or no maintenance. Heavy duty cast aluminum airfoil or polyamide glass reinforced (PAG) blades are standard to ADD series fans providing maximum performance at low sound levels. Applications include factories, warehouses, gymnasiums, underground parking garages, etc. This fan is used for exhaust applications. Please consult factory for supply applications. OPTIONAL - Reversing blades available on 30”, 36”, 42” and 48” models. Consult factory for details.

Theses light commercial EC motor units have the following operating principle: the air from the room enters the unit and is cleaned by the extract filter.

Theses light commercial EC motor units have the following operating principle: the air from the room enters the unit and is cleaned by the extract filter. Then the air is moved through the heat/energy recovery core and is exhausted outside with the extract fan. Air from outside flows into the unit, where it is cleaned by the supply filter. Then the air flows through the heat/energy recovery core and is directed to the room with the supply fan. Heat energy of warm extract air is transferred to clean intake fresh air from the outside and warms it up. The air flows are fully separated while flowing through the heat/energy recovery core. Heat recovery minimizes heat losses, which reduces the cost of space heating in the cold season

TDC duct fans are suitable for application where motor location in the air stream is satisfactory. Direct driven models require less maintenance, offer longer operating life and increased efficiency. The propeller assembly is connected directly to the motor shaft. There are no fan bearings or belts that require maintenance. TDC models ha
TDC duct fans are suitable for application where motor location in the air stream is satisfactory. Direct driven models require less maintenance, offer longer operating life and increased efficiency. The propeller assembly is connected directly to the motor shaft. There are no fan bearings or belts that require maintenance. TDC models have from 3 to 6 cast aluminum airfoil blades that are securely attached to a heavy cast aluminum hub. Blade pitch is set for catalog performance. Type TDC fans incorporate specifically engineered airfoil sections and hub sizes for optimum efficiency and physical strength. TBC & TBC-H Belt Drive Tube Axials are also available. Reversing blades available on many models. Consult factory for details.
