One Piece Moulded fans

One-Piece fan l noise reduced up to 10 dB l 5% increased efficiency l fixed pitch angle l number of blades customizable l PAG or PPG

Multi-Wing’s One-Piece Moulded fans are the optimal solution for high volume projects. The process of preparing your ultimate one-piece moulded fan starts with an in-depth discovery phase of every aspect of your application. Functional points, geometry, noise levels, operational and inlet conditions, balancing grade and many other variables are then considered. 

The one-piece moulded custom fan reduces noise by up to 10 dBA and increases efficiency by 5%. It provides excellent performance while reducing energy and noise consumption. The One-Piece Moulded fans work with PAG in a temperature range from -10 °C to +110 °C (14°-230°F) and PPG materials in a temperature range -10 °C to +80 °C (14°-176°F).
