T35-11 Series Low-Noise & Industrial Axial Flow Fan

1. The T35-11 axial fan features a wide, forward-swept, constant-pitch blade design, which reduces airflow separation and vortex formation on the blade surface, minimizes secondary airflow losses inside the fan, reduces aerodynamic sound source noise, and stabilizes the airflow. It is divided into 14 standard specifications by diameter ranging from 250 to 1,100 mm, with each specification using 4 blades. By structural configuration, it can be classified into wall-mounted and ducted types. By operating environment, it is categorized into: Standard Type, suitable for non-flammable, non-explosive, and non-corrosive gas environments; Anti-Corrosion Type, featuring a fiberglass-reinforced plastic (FRP) impeller and casing; and Explosion-Proof Type, equipped with an explosion-proof motor and aluminum alloy blades, with an explosion-proof rating of ExdIIBT4. To meet noise requirements in different locations, all fans can be equipped with silencers of varying lengths.

2. Prior to installation, a detailed inspection must be conducted to check for any damage or deformation. During installation, check all connection parts for looseness; the clearance between the blades and the casing must be uniform without any contact. Pipelines connected to the fan ports should be supported independently, and an air collector must be installed at the fan inlet end. When installing the mounting base, it must naturally align with the foundation surface; hammering the base for forced connection is strictly prohibited to prevent base deformation. The base should be calibrated with shims added during installation. After installation is complete, perform a test run, and official operation may only begin after confirming normal performance.

3. If a duct needs to be connected to the outlet, the connection method must be considered to reduce the dynamic pressure loss caused by airflow diffusion inside the duct. When the duct diameter equals that of the fan casing or Fmp/F1≤1.5 with a duct length of no less than 5 to 8 times the internal duct diameter, the duct diffusion loss can be neglected. When 1.5≤Fmp/F1＜2.5 or Fmp/F1＞2.5, a diffuser must be installed between the duct and the fan. If applied in a long exhaust pathway, fans can be installed in series at intervals to increase static pressure, but two adjacent fans should not be spaced too far apart.
