A DC cross-flow fan draws air in from one side of the fan housing and expels it in a perpendicular direction of the fan across its length, thereby creating a broad and laminar airflow pattern. This fan is also known as a tangential cross flow fan due to its tangential airflow pattern. Powered by DC sources, these fans are used in applications requiring efficient ventilation or cooling in compact spaces.

Longwell Technology is a designer, manufacturer, and distributor of high quality, cost effective, RoHS, certified AC cross flow fans, (voltages 110v – 120v & 220v -240v ) in AC capacitors as well as shaded pole motors. We have professional service teams in the United States, Russia, Germany, Poland, Turkey, and China, among other locations. Our Industrial crossflow fans, often referred to as tangential or blower wheel fans, will generate a wide, even flow of air parallel to the unit being cooled, insuring greater efficiencies and lower noise ratios per cfm when compared with axial fans. Impellers range in size from 60mm to 1200mm in wheel diameter for an ac capacitor type motor and from 30mm to 150mm in wheel diameter for a shaded pole motor. The fan’s motor location can be changed from the right side to the left side by the factory at the customer’s request. Additional modifications allow two impellers to be mounted to a single motor, one impeller on either side of the motor housing. 3rd wire options are also available on all Industrial crossflow fans: signal-rotation detection, signal-frequency generator function as well as temperature control for operating environments where noise and temperature are a consideration. Various speeds are also available.perpendicular direction of the fan across its length, thereby creating a broad and laminar airflow pattern. This fan is also known as a tangential cross flow fan due to its tangential airflow pattern. Powered by DC sources, these fans are used in applications requiring efficient ventilation or cooling in compact spaces.
EC cross-flow fan, also known as an electronically commutated cross flow fan, is a type of fan that utilizes an electronically commutated motor (EC motor) for its operation.
Cross-flow fans are designed to produce a wide, uniform airflow. They have a cylindrical housing with an impeller wheel that extends across the diameter of the housing. As the impeller rotates, it draws air in through one side of the housing and expels it out the other side, creating a consistent flow of air across the entire length of the fan.
The electronically commutated motor used in an EC cross-flow fan is a brushless DC motor that offers several advantages over traditional AC motors or standard DC motors. EC motors are more energy-efficient, quieter, and offer variable speed control, allowing for precise adjustment of airflow. They also typically have a longer lifespan and require less maintenance compared to other types of motors.
LONGWELL technology provides EC cross flow fans with various performance characteristics, materials, with EC External Rotor Motor.Our ec cross flow fan product line encompasses a wide selection of tangential cross flow fans in 80mm to 150mm impeller sizes and in steel+aluminum alloy housing. Our EC cross flow fans are designed for horizontal mounting. We can provide them with options, such as special IP ratings, left and right-hand motor configurations, etc.
