The Twister Fan is a portable, high velocity outdoor Stirling engine fan which you can use on any table top to keep cool and repel insects naturally.
It’s robust design means you can take it anywhere – even on on camping and caravanning holidays. Plus because it is powered by an alcohol burner, you have no reliance on electricity or battery power. This makes it ideal for off grid living, camping, bush and hunting lodges.
The practical design includes an integral essential oil diffuser which can be filled with Citronella or Peppermint oil to assist in repelling insects.
You can use any form of denatured alcohol, Methylated Spirits or eco-friendly bio ethanol fuel to power the Twister fan. Read more about bio ethanol fuel here.
When the burner is filled, the engine will run and keep you cool for approximately 12 hours (depending on your wick setting). At peak output the Twister Outdoor Fan will move in excess of 442 CFM (cubic feet per minute) of air.
PLEASE NOTE DUE TO A GLOBAL SHORTAGE OF PRECISION GLASS AND A LACK OF SUPPLY, THE BOROSILICATE GLASS PISTON SLEEVES MAY BE UPGRADED TO BURNISHED ALUMINIUM SLEEVES. THE ALUMINIUM PISTON SLEEVES OFFER SLIGHTLY IMPROVED PERFORMANCE.
Stirling Engine Design
Warpfive fans are small precision engineered Stirling engines, which are 100% mechanical and do not have any electric components which may stop working if overheated. Consequently they are extremely reliable and with care will last a lifetime.
Every engine is precision engineered and hand built with durable materials like stainless steel, aluminium, brass and Borosilicate glass. As a result they operate quietly – typically 28dB.
Advanced materials (such as graphite) and low friction bearings ensure low maintenance, plus heat flow is optimised with a silver thermodynamic heat plate.
Stirling engine fans have a high power output and low start up speed so they move large volumes of air.
Every engine is hand-crafted, assembled and tested in Great Britain.
