T35-11, BT35-11 Axial Flow Fans

Applications

The T35 axial flow fan was developed primarily as a replacement for the 30K4, a product introduced from the former Soviet Union in the 1950s. The 30K4 was analyzed and compared with similar products from abroad, and model tests were conducted. The fan blade profile was determined, a cylindrical hub structure was adopted, and the motor was redesigned. The structural design reduces flow losses, increasing fan efficiency to 77% when calculated based on the outlet area and to 89.5% when calculated based on the outlet annular area. The A-weighted sound level is reduced by 3.6 dB, and the blade-root strength is increased to prevent blade breakage.

The BT35 explosion-proof axial flow fan incorporates explosion-proof measures and is equipped with an explosion-proof motor. It can therefore be used in non-corrosive environments containing flammable or explosive gases as general-purpose explosion-proof ventilation equipment. T35 and BT35 axial flow fans can be used for ventilation in general factories, warehouses, offices, and residences, or to enhance heat dissipation from heating systems. With the casing removed, the fan can also be used as a free-standing fan. Multiple units can also be installed in series at intervals along a long exhaust duct to increase the air pressure in the duct.

Configurations

This product series comprises 13 fan sizes, categorized by impeller diameter: No. 2.8, 3.15, 3.55, 4, 4.5, 5, 5.6, 6, 6.3, 7.1, 8, 9, 10, and 11.2. Each size is available with five blade angles: 15°, 20°, 25°, 30°, and 35°.

All products in this series feature a direct-drive design, with the impeller mounted directly on the motor shaft. Three speeds are available when the impeller peripheral speed does not exceed 60m/s: 2900r/min, 1450r/min,

and 960 r/min. Viewed from the air inlet, the impeller rotates counterclockwise, with air entering at the impeller end.

The gas conveyed by T35 and BT35 fans must be non-corrosive and free of significant dust, with a temperature not exceeding 40℃. BFT35 fans can convey various corrosive gases (with no dust), at temperatures not exceeding 60℃. All fans undergo a running test before leaving the factory to ensure smooth operation.

Construction

BT35 and T35 fans mainly consist of an impeller, casing, and motor. The support, made of high-quality carbon steel plate, is connected to the fan cylinder. The impeller assembly consists of blades and a hub. Nylon adjustable-pitch impellers and aluminum alloy impellers are also available. The casing assembly consists of the fan cylinder and support, both made of high-quality carbon steel plate. The fan cylinder is cylindrical, with a specified clearance between it and the impeller. An inlet collector can be fitted; it is formed in one piece from outer-cylinder steel plate and helps reduce inlet airflow losses.

Performance and Selection

The fan performance values in the performance tables are for air under standard conditions (temperature 20℃, relative humidity 50%, atmospheric pressure 101.3X10³Pa, air density 1.2kg/m³). If the fan operates under non-standard conditions, the performance values must be converted. Fan performance at different rotational speeds can be calculated using the relevant formulas.
