Twinspeed Stove Fan
The Twinspeed Stove Fan is the most powerful Stirling engine we produce. This premium engine moves an impressive 440 CFM (cubic feet per minute) of air.
Named the Twinspeed for its ‘twin’ piston design, this stove fan will start working at 120° C (248° F). In addition to double pistons, the Twinspeed includes dual pulleys and a belt mechanism, ensuring higher propeller speeds and superior performance. The propeller is 220mm (8.6 inches) in diameter.
This beautiful Stirling engine is precision engineered from durable materials such as stainless steel, brass and alumimium. Its exceptional performance is optimised with a silver thermodynamic heat plate, precision bearings and other advanced materials such as graphite. The glass piston cylinders and low friction bearings ensure quiet operation and low maintenance.
The Twinspeed comes with a stainless steel base which provides improved thermodynamic properties. Furthermore it has a stainless steel displacer and regenerator which both boost performance. The stainless steel base is extremely attractive and the added weight provides additional stability.
When you order a Warpfive Twinspeed you will also receive an attractive dust cover. The dust cover is a beautiful clear dome which can be used while the engine is in use. Not only does it enhance the beauty of the engine, it also assists in keeping the stove fan ash / dust free. The dust cover is a useful addition when you clean your stove as it helps to prevent air borne ash contamination, and it can also be used to protect the engine while in storage during the summer months. In addition, you will receive a comprehensive tool kit which includes all the essential items for maintaining your stove fan on a seasonal basis.
