The WF20 is widely used by International Naval Fleets around the world providing high performance AMCA Certified airflows in the rapid removal of smoke in emergency situations.
The Ramfan WF20 is a water powered Positive Pressure Ventilation (PPV) fan designed for rapid smoke removal in firefighting and emergency situations. It uses the water pressure from a fire hose to drive a patented turbine and high efficiency fan blade, generating high velocity airflow without the need for electrical power. It is widely used by naval fleets and fire services for removing smoke from confined or hard to reach spaces, often using ducting to extract smoke from deep within structures or vessels.
The WF20 delivers high performance airflow of approximately 10,600 cfm (18,000 m³/hr) in standard PPV operation. When used with ducting, airflow is typically around 1,835 cfm (approximately 3,100 to 3,500 m³/hr), depending on setup and operating pressure. Higher airflow outputs can be achieved in certain configurations, exceeding 13,000 cfm depending on pressure and accessories.
The WF20 is fully water powered, operating using fire hose pressure rather than electricity or fuel. It typically operates within a pressure range of approximately 40 psi to 250 psi, making it suitable for use with standard fire mains and onboard water systems. This design makes it intrinsically safe for hazardous environments, as it eliminates electrical components and reduces the risk of sparks.

The 3 people I deal with most at Delta are Richard, Lisa and Ashley. They never let me down and are always ready to help and assist with any enquiries I have.

Delta fire is highly recommended my me.

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
