Product Description

75x75x30mm DC Waterproof Blower Fan 7530 12V 24V IP68 With Waterproof Glue

What is a DC cooling fan?
DC fans also known as DC Brushless Fans are basically cooling fans engineered to meet requirements such as higher air flows at high static pressures. RENGANG manufactures Brushless DC fans in varied sizes ranging from 60 mm to 280 mm. These fans are available in the plastic blade as well as the metal blade.

What are axial fans used for?
In general, an axial-flow fan is suitable for a larger flow rate with a relatively small pressure gain and a centrifugal fan for a comparatively smaller flow rate and a large pressure rise. They are used to supply fresh air, suck air from return air trenches, suck air from rotary filters, exhaust air out, etc.

Q5. What are DC Fan and AC fans?
DC fan is power by DC voltage, always is 5V, 12V, 24V, 48V, 60V, and 72V. AC fan is power by AC voltage, always is 110V, 220V, and 380V.
Q6. How do we carry out quality control?
Usually, there are two ways to monitor reliability during the manufacturing process. Early Life Test This is used as a means of process control to identify any latent manufacturing problems and determine the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn-in at 50C+/-5C for 24 hours. On-going Reliability Demonstration This is a longer-term program that provides data that continues to demonstrate the product's reliability. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at 50C+/-5C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions are taken where necessary.
