In fact, the fire fan is divided into single speed and double speed.

When we choose fire fans, single-speed and double-speed fire fans should pay attention to those usage problems!

Today, I found some information on single-speed and dual-speed fire fans on the Internet, and share with you;

Pay attention to the use of single-speed fire fans:

1. Before unpacking the fire fan, check whether the packaging is intact, whether the nameplate parameters of the fire fan meet the requirements, and whether the accompanying accessories are complete and complete.

2. Carefully check whether the fire fan is deformed or damaged during transportation, whether the solid parts are loose or falling off, whether the impeller is rubbed, and check all parts of the fan.

If an abnormal phenomenon is found, it should be repaired before use.

3. Use a meter to measure the insulation resistance between the fire fan shell and the motor windings. The value should be greater than megohm, otherwise the motor windings should be dried. The temperature during drying is not allowed to exceed 120 degrees.

4. Prepare all the materials, tools and sites required for the installation of the fire fan.
