FRP Fan

The FRP Fan, also known as a fiber-reinforced plastic fan, is engineered as a fully non-metallic, integrally molded, corrosion-resistant ventilation solution. Designed in compliance with GB/T 13275, GB/T 2888, HG/T 20696, and ASTM D5364 standards, it delivers exceptional performance in applications where traditional metal fans fail. Made from glass fibers reinforced with unsaturated polyester, epoxy, or vinyl ester resins, the fan achieves a strength-to-weight ratio superior to ordinary steel, along with outstanding resistance to corrosion, aging, and electrical conductivity. This makes the product a cost-effective and technically sound choice for handling sulfuric, hydrochloric, and phosphoric acids, alkaline gases, and salt-laden atmospheres commonly encountered in electroplating, pickling, and wastewater treatment.

Constructed using seamless molding techniques, the FRP Fan integrates the casing and impeller into a single, rigid unit, completely eliminating weld-related corrosion risks. The backward-curved aerodynamic impeller-typically only one-third to one-half the weight of a metal equivalent-ensures rapid start-up and low inertial load. The resin matrix can be tailored to specific chemical exposure: epoxy for alkali resistance, isophthalic polyester for acid resistance, or vinyl ester for broad chemical and elevated-temperature service. A UV-resistant protective gel coat is also available for outdoor installations. With a rated airflow of 10,000 m³/h and total pressure of 600 Pa, the fan maintains measured performance between 9,800–10,200 m³/h and 580–620 Pa, operating at 72–75% efficiency.

In critical systems such as coastal power plant wet flue gas desulfurization (FGD), the product demonstrates long-term reliability. It handles saturated, low-temperature flue gas containing residual SO₂, SO₃, and chlorides-a highly corrosive "acid dew point" environment that rapidly degrades carbon steel. Installed at the scrubber outlet, the vinyl ester resin construction provides excellent resistance to these conditions. Its lightweight design reduces structural load on support systems, and maintenance can be performed safely without hot work. Offering a significant lifecycle cost advantage over expensive alloy metal fans, the FRP Fan serves as a reliable, cost-effective backbone for sustainable industrial air-handling systems.
