WF390 PPV FAN

Motor: 22.3 HP
Airflow (AMCA Certified): 17,417 cfm
Weight: 27kg (60lbs)
Product Code: MIS050000
The Ramfan WF390 is a water powered Positive Pressure Ventilation (PPV) fan designed for rapid smoke removal, ventilation, and cooling in firefighting operations. It uses a pressurised water supply to drive a turbine system that generates high velocity airflow without the need for electricity or fuel, making it suitable for hazardous environments.
The WF390 is a larger, wheeled PPV fan designed for broader area ventilation, while the WF20 is a more compact unit typically used for confined or shipboard spaces with ducting capability. The WF390 delivers significantly higher free air movement and is better suited to large open structures or wide area smoke clearance operations.
The WF390 is used in fire and rescue operations, naval and marine environments, industrial sites, utilities, and petrochemical facilities where large volumes of smoke must be cleared quickly. It is particularly effective for building ventilation, post fire clearance, and creating safer access routes for firefighters by improving visibility and reducing toxic smoke layers.

Fantastic equipment and customer service. Would high recommend Delta Fire to any company looking for fire service equipment. After doing a lot of market research, I found and contacted Delta Fire to get more information about their equipment. Any questions I had where answered, they helped me look at my company's needs and pick which products where best suited. Extremely helpful. To add the very long warranty and that they are UK made is what separates the from the rest. Thank you guys for all your help. 10/10
