What is the Ram Fan pressure rating?

• A. 100 psi
• B. 120 psi
• C. 150 psi
• D. 180 psi

Answer: (C)

The Ram Fan pressure rating is the maximum safe air pressure the fan is designed to handle in operation. It ensures the fan, its seals, and connections stay within their design limits while delivering the needed airflow. For the Ram Fan used in this material, that safe operating limit is 150 psi. This value provides enough pressure to drive adequate airflow for ventilation and cooling without stressing the equipment beyond what it’s built to tolerate. Pressures lower than that (like 100 or 120 psi) may not move air effectively, while a higher rating (such as 180 psi) could push the hardware beyond its safe limit and risk damage.
