PPV Fans – Water
Water powered RamFan Turbo PPV Fans are used by Naval Forces worldwide for smoke removal, ventilation and cooling during combat operations. The water powered design eliminates the threat of electrical shock and minimises explosion potential in dangerous gas environments. RamFan’s patented Axial Flow Turbine Technology leads the way in converting water power into high velocity airflow more efficiently than any water fan on the market today, the Axial Turbine is built of corrosion-proof composite materials for long life, simple maintenance and easy replacement of parts.
Delta Fire have supplied The Royal Navy for 10 years with the WF20 PPV Fans.
No portable blower in the world compares with the smoke removal rates of this blower when connected to ducting from 8″ to 12″. Warships at general quarters require powerful suction to remove smoke from interior spaces. The WF20 sucks the smoke from the affected areas via long lengths of ducting to the outside air. At normal fire main pressures of 8 to 10 bar the WF20 makes about 4.5Hp with a 190 litre per minute flow rate.
This range of PPV Fans uses the water pressure energy of a fire hose and a patented turbine, coupled to a high-efficiency fan blade, to generate high-velocity, high pressure airflows. The modular construction, choice of corrosion-resistant materials and simplicity assures infrequent and simple maintenance.
Exhaustive testing during U.S. Navy evaluations left the WF20 as the uncontested champion of shipboard smoke removal.
The WF20 can be easily fitted with the Multiplier/Mister accessory which injects up to 13 litres of water per minute into the airstream producing a highly effective Cooling Mist which has proved to be beneficial in the creation of heat migration boundaries, cooling of personnel and even catapults and aircraft wheels. This Venturi device doubles the airflow and is intrinsically safe in hazardous conditions.
The WF20 can be supplied with a number of different Adaptors for attaching the ducting hoses and the water connections can be fitted with any British or International adaptors .
The RamFan range of PPV Fans are manufactured under the stringent requirements of an ISO9001 Quality Management Standard and are fully checked and tested prior to dispatch. Reliability is of paramount importance when dealing with Smoke Extraction and Delta’s partnership with the RamFan range of PPV Fans has seen many customers put these fans through rigorous use over the years building a reputation for reliability, durability and performance. Delta Fire have supplied The Royal Navy with water driven RamFan’s for more than 10 years which testifies to their capabilities in the harshest of environments.
