Meet Mellizo

S&P UK is excited to unveil Mellizo – the quietest and most efficient twin fan we’ve ever made!
Mellizo is versatile, cutting-edge and eco-friendly, and is designed for simple installation in environments such as bathrooms and changing rooms.
Spanish for ‘twin’ to reflect our heritage, Mellizo is the result of significant research and development across S&P, channelling our collective minds and expertise to set new industry standards for twin fans.
Mellizo has the lowest Specific Fan Power possible and is packed with cutting-edge technology inside its durable steel sheet casing.
It is also designed for indoor and external installation with horizontal and vertical mounting.
You can’t hear how good it is, so we’ll have to tell you…
“We’re incredibly excited and proud to be launching Mellizo – a genuine game-changer for twin fan performance.“
