Overview

The new T4-72-12 centrifugal fan is an improved, redesigned, and developed version of the original T4-72-11 fan. This centrifugal fan offers high efficiency and low noise, with a flat performance curve, a wide effective working range, and a high-efficiency zone. Available in sizes No. 3, 32, 4, 4%, 5, 6, 8, and 10, the installation dimensions match the original T4-72-11, except for the motor, which has been upgraded to a high-efficiency Y series motor.

1) Application

The T4-72-12 fan serves the same purpose as the original T4-72-11 fan, suitable for general ventilation. It is ideal for indoor ventilation in general factories and large buildings, smoke and dust removal, and boiler blasting. This centrifugal fan can handle both input and output gases, such as air and other non-self-igniting, non-corrosive gases harmless to humans. The gas should not contain sticky substances, and dust and hard particles should not exceed 150mg/m³, with a temperature limit of 80℃.

2) Type

The fan is available in right-hand and left-hand rotation. When viewed from the motor end, a right-hand rotation fan's impeller rotates clockwise, denoted as "right." A left-hand rotation fan's impeller rotates counterclockwise, denoted as "left." The fan outlet position is indicated by the casing's outlet angle. T4-72 fans No.3 to No.6 are manufactured in one form and can be adjusted to the required position by the user. The outlet position adjustment range for No.3 to No.32 is 0°~210° in 30° intervals, and for No.4 to No.6, it is 0°~225° in 22.5° intervals. The transmission mode for No.3 to No.6 is A-type. For No.8 to No.10, the outlet is fixed at 0°, 90°, or 180° and must be specified when ordering. The transmission mode for No.8 to No.10 is C-type.

3) Overall Structure

Fans No. 3 to No. 6 consist mainly of impellers, casings, air inlets, and direct-connected motors. Fans No. 8 to No. 10 also include transmission parts.

Impeller: Balanced to ISO international standard G6.3, ensuring minimal vibration and stable operation after dynamic and static balance correction.
Casing: Fans No.3 to No.10 are made in one piece, non-disassemblable, and usable on both sides. The impeller can be removed from either side but cannot be used interchangeably.
Air Inlet: Integral part installed on the fan side, with a curved section parallel to the axial direction for smooth gas entry and minimal loss.
Transmission Part: Comprises the main shaft, bearing box, rolling bearing, and pulley.

4) Performance and Selection

Fan Performance: The fan's performance is indicated by parameters such as flow rate, total pressure, main shaft speed, shaft power, and efficiency, with interrelated parameters.
Fan Selection: The performance listed in the product performance and optional parts table is based on standard conditions. For non-standard conditions, convert the performance to standard conditions using the "fan performance parameter relationship formula" before selecting from the performance table.

The T4-72-12 centrifugal fan, also known as an ID fan or boiler fan, is designed for efficient and reliable operation in industrial applications such as smoke and dust removal, boiler combustion air supply, and general ventilation.
