Product Description

Custom Rotomolded Plastic Blower Housing

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.

We purchase full range tapered rotomolded barrels from 50L to 5000L to match diversified raw material storage of our integrated chemical factory. The tapered design facilitates complete material pouring without leftover residue, seamless one-piece PE structure prevents leakage of granular and mild corrosive liquid raw materials.
