Attwood Quiet Blower (White, 4-Inch)
Attwood's new and improved Turbo 4000 Series II sets the standard for in-line blower performance. Utilizing advanced fan blade design techniques, Attwood has developed a blower system that matches air flow of existing in-line blowers at a significantly reduced noise level. For added durability, Attwood incorporates an engineered plastic housing that resists deformation during installation and prevents blade to housing interference.
