Frequently Asked Questions

How to choose a fan from RAMFAN?

  • Power Source: Electric power is used in stationary applications, whereas battery power is used in portable applications.
  • Airflow Requirements: Factors like impeller design, impeller diameter & input power determine the airflow required for ventilating the desired area.
  • Size Requirements: Users should determine the size of the fan required. A large-sized fan offers greater airflow but consumes larger space.

What is entrained air in ventilation applications?

Entrained air refers to the natural effect created when high-velocity airflow pulls the air next to it into the flow path. The ventilation fans create large amounts of entrained air. Therefore, the users must include the entrained air going through the opening when measuring airflow to calculate the practical ventilation offered by the fan.

What are RAMFAN Kraken charging hubs?

Charging hubs are ideal for supplying continuous onboard AC power to recharge batteries. These battery tool charging hubs can store energy and transport it to the desired location for charging tool batteries continuously.
