30mm DC 12V DC24V Cross Flow Fan - Single and Double (Length up to 1050mm)

What is the difference between an AC cross flow fan and a DC cross flow fan?

- DC fan motors are 70% less efficient than AC fans - Quieter operation, down to 19 dBA levels. - Suitable for extreme temperature environments; - Provides more variable, uneven airflow with minimal electromagnetic interference - Low voltage operation - Integrated PCB control system.

Longwell offers different types of DC cross flow fans with 3-phase BLDC motors. This tangential fan has the option of a safety barrier and a speed controller.

housing:We supply metal housings, mostly aluminium.impeller:Our impeller diameters range from 25mm to 150mm and lengths from 76mm to 1200mm (single double triple type).Bearings:We offer NMB or NSK ball bearings for tangential fans.Voltage:Our DC cross flow fans are available for 12V, 24V and 48V.

FAQ:

Q1. What are the advantages of your cross flow fan? -LONGWELL cross flow is specially designed for low noise purpose. The noise is even as low as 19 dBA; - Our production range is from 20mm to 200mm; - We have heavy duty design with 4000rpm for fans with diameter less than 60mm and over 2700rpm for fans with diameter of 150mm.

Q2. Does Longwell offer any speed control options for DC cooling fans?

Re: Yes, Longwell can provide some speed governor solutions according to customer's requirements, such as: - 0-10V/pwm controller for full range of cross flow fans/DC cooling fans. It is powered by 10VDC and provides infinitely variable manual speed control between 0% and 100%; - can control multiple fans to run at the same speed; - infinitely variable control knob for infinitely variable settings.

Q3.How do we connect the tangential fan to our application, is there a wiring diagram?

Reply:

Please check the speed control of your application first (is it PWM or 0-10V),Please refer to the 0-10v series wiring diagram as follows:
