The Workhorse for Demanding Corrosive Ducted Systems

The Medium pressure corrosion-resistant fan is engineered to address the core ventilation challenges of industrial processes in which corrosive gases must be conveyed through ductwork, scrubbers, or filtration systems. Operating within the critical total pressure range of 1–3 kPa, this fan balances strong pressure capability with dedicated corrosion protection. It is widely applied in chemical plant exhaust systems, wastewater treatment odor control, and battery manufacturing ventilation. Designed in accordance with relevant industry standards, the fan delivers reliable, continuous performance in environments where both chemical attack and system resistance are significant.

Engineered for Efficiency & Durability in Tough Conditions

The Medium pressure corrosion-resistant fan typically employs a backward-curved centrifugal impeller to achieve high efficiency within its operating pressure range. Construction materials are selected to match the specific corrosion profile and may include full 316L stainless steel, molded FRP, or steel lined with corrosion-resistant plastics such as PO. The motor is a fully enclosed, corrosion-protected unit designed for operation in damp, aggressive atmospheres. Critical design features-such as isolated bearing housings, corrosion-resistant shaft sleeves, and smooth, crevice-free welds-are standard, preventing the accumulation of corrosive condensate or particulates. As a result, the medium-pressure corrosion-resistant fan consistently delivers performance that closely matches its design specifications, ensuring dependable system integration.

Critical Role in Environmental & Process Air Systems

In municipal wastewater treatment plant biofilter systems, for example, the Medium-Pressure Corrosion-Resistant Fan functions as the heart of the system, drawing foul air containing H₂S and NH₃ from collection networks and conveying it through the filter media. Its ability to maintain stable pressure (for example, approximately 1,500 Pa) is essential for uniform gas distribution and effective treatment. The fan's construction-often entirely FRP-resists moist, chemically laden air streams, while its reduced weight lowers structural loads and energy consumption. This combination of corrosion resistance, pressure capability, and operational reliability makes it a cornerstone of effective industrial air pollution control and process ventilation systems.
