FRP Square Wall Mounted Fan

1.Product Overview​​

Square wall-mounted fans are engineered for ​​high-efficiency exhaust and supply ventilation​​ in confined spaces where circular ducting is impractical. Longxuan's square axial fans feature a ​​low-profile housing with aerodynamically optimized blades​​, delivering ​​20-35% higher airflow efficiency​​ compared to traditional round fans at equivalent power inputs.

​​2.Key Design Features​​

1.Space-Saving Square Housing​​

Precision-formed galvanized steel casing (1.2mm thickness) with flanged edges for ​​seamless wall integration​​

Standard sizes: 300×300mm to 1200×1200mm (custom sizes available)

2.Advanced Blade Geometry​​

Glass-reinforced nylon (GRN) or aluminum alloy impellers with ​​airfoil cross-section​​

Blade tip clearance <0.5% of diameter for minimized leakage

3.Weatherproof Construction​​

IP55 rated motor compartment with self-draining weep holes

Optional louvered rain hood (motorized or gravity-operated)
