1. First of all, when the Roots blower fails, it cannot be used, even if it is a minor fault, it cannot continue to run. If it continues to be used, it can lead to serious damage and paralysis after the purchase of new equipment, so we need to understand that when there is a failure, it must be repaired, so as to reduce expenses.

2. Toxic gases can not be transported through the Roots blower, even if the special material is sealed, the risk factor is quite large, so toxic gases can not be transported.

3. The transported flammable and explosive gas requires special treatment of the Roots blower before use. The blower cannot be used without special treatment

4. It cannot be used in an environment with a large dust concentration. If the operation instructions of the Roots blower are not followed or used in this environment, a large number of dust particles will enter the inside of the Roots blower, so that the two impels contact and wear, and maintain a dead zone after the gap is too small. Engines can also burn out in severe cases.

5. The entrance temperature of the Roots blower exceeds 40°C, and the Roots blower is prone to failure. Therefore, if the intake temperature of the Roots blower exceeds 40°C, the operation should be stopped.

6. When the exit pressure exceeds the rated pressure of the label or the motor current exceeds the rated current, it cannot be used.

If your Roots blower has the above conditions, please stop using the old equipment, and buy a new equipment to replace it.
