The blade/motor/frame/protect net/bracing cage/shutters are the key components of a drop hammer fan. The motor drives the blade to provide airflow, and the louvre window can open and close on its own to prevent dust from getting in. Extra-deep zinc coating and modern automation processing give the frame height precision and great corrosion resistance. High-strength aluminum alloy casting pulley, and reasonable perspective blade, to achieve the maximum air flow. High-strength aluminum alloy casting pulley, and reasonable perspective blade, to achieve the maximum air flow. There are five exact quality testing procedures that are done at the factory to ensure the best quality product is delivered to our customers: noise detection, vibration testing, concentric rotation performance testing, speed of blade testing, and total fan efficiency detection.
-
Increased efficiency
Direct drive motors transfer power more efficiently to the impeller, which can increase the fan's overall efficiency and reduce energy consumption.
-
Improved reliability
The direct drive design eliminates the need for belts and pulleys, reducing the number of mechanical components that can wear out or break.
-
Durable
These fans are typically built with heavy-duty construction materials such as steel and cast iron and are designed to handle high temperatures and abrasive materials.
-
Easier to maintain
With fewer mechanical parts, direct drive fans are easier to maintain, reducing the time and cost associated with maintenance.
