Thick Anti-Corrosion LLDPE Fan Shell for Industrial Ventilation Air Blower Equipment
Product Overview
This custom rotomolded plastic blower housing is an integrated seamless fan shell manufactured by SUNMORE ROTO. Utilizing thick industrial-grade LLDPE raw material, it is formed through one-time rotational molding without splicing or welding seams. The product offers excellent anti-corrosion, anti-aging, impact resistance, and lightweight performance, effectively replacing traditional metal blower casings that are prone to rust. Suitable for factory workshop exhaust ventilation, agricultural breeding ventilation, aquaculture air supply, construction engineering air blowers, sewage treatment plant deodorization ventilation, and other industrial ventilation equipment applications. Full OEM customization service available.
Key Features & Benefits
Integral Seamless Rotomolded Structure: One-step rotational molding creates a complete fan housing without welding joints, eliminating air leakage and improving ventilation efficiency. Thickened wall design with built-in reinforcing ribs provides strong compression and impact resistance.
Thick Industrial LLDPE Material: Uniform thick anti-aging LLDPE polyethylene material resists acid, alkali, salt, waste gas, and sewage volatile gas corrosion. Will not rust like iron blower shells, suitable for long-term use in corrosive environments.
UV Stabilized Raw Material: UV anti-aging masterbatch added during production enables the blower shell to withstand long-term outdoor exposure without embrittlement, fading, or deformation.
Lightweight & Easy Processing: Plastic material density is much lower than metal, making the housing lightweight for easy lifting and installation. The shell can be drilled, tapped, and flanged to match various blower motor and fan blade assembly standards.
Multi-Size & Multi-Color OEM Customization: Multiple standard specifications available with support for custom colors including blue, orange, and black. Air inlet/outlet size, flange hole position, wall thickness, and overall outline can be adjusted to match various industrial ventilation equipment.

Frequently Asked Questions
Can the blower housing size, air inlet/outlet and flange structure be fully customized?
Yes, we provide full OEM customization service. We can adjust the overall dimension, wall thickness, air duct caliber, flange hole layout and exterior color according to your blower equipment design drawings to match motor and fan blade assembly.
Is this plastic blower shell suitable for corrosive waste gas environment of sewage plants and chemical factories?
The housing is made of thick LLDPE with excellent acid, alkali and salt corrosion resistance, no rust, can stably operate in corrosive waste gas environment for a long time.
Can the rotomolded blower housing be used outdoors all year round?
UV anti-aging masterbatch is added to raw materials, resisting long-term sunlight and rain erosion, no embrittlement or fading, suitable for permanent outdoor ventilation equipment installation.
