High Pressure High Speed Aeration Blower

This High Pressure High Speed Aeration Blower, developed for water treatment aeration and aquaculture oxygenation scenarios, is a dedicated aeration blower device with high pressure, high rotational speed, and high efficiency. In sewage treatment and aquaculture, aeration blowers are core equipment - injecting air into water to provide oxygen for microorganisms (sewage treatment) or dissolved oxygen for aquatic products (aquaculture). Traditional Roots blowers and rotary blowers have problems such as high energy consumption, high noise, high maintenance costs, and unstable oil pressure, and are inefficient in deep-water aeration scenarios requiring higher pressure. Our High Pressure High Speed Aeration Blower uses a high-speed permanent magnet synchronous motor direct-drive ternary flow impeller structure, eliminating gearboxes and couplings, with maximum speed up to 25,000rpm, maximum pressure up to 30kPa, and maximum airflow up to 8,000m³/h, meeting high-pressure needs for deep-water aeration above 5 meters. Device transmission efficiency reaches over 95%, saving 35%-45% energy compared to traditional Roots blowers, significantly reducing operating electricity costs for sewage treatment plants and farms.

For intelligence and reliability, this High Pressure High Speed Aeration Blower is equipped with a high-performance frequency converter and dedicated aeration control system, automatically adjusting speed and air supply based on dissolved oxygen (DO) concentration in water - automatically increasing airflow when DO concentration is below the set value, reducing airflow when DO concentration reaches standard, achieving on-demand aeration and precise oxygen control, avoiding energy waste from over-aeration. The control system has multiple protection functions such as overvoltage, overcurrent, overheat, overload, and undervoltage, real-time monitoring parameters such as bearing temperature, motor temperature, wind pressure, and airflow, automatically alarming or shutting down for protection when abnormal. The device uses air cooling or water cooling (optional based on power), ensuring no over-temperature during long-time high-speed operation. Impellers use high-strength aluminum alloy or titanium alloy material, precision milled by a five-axissimultaneous machining center and 100% dynamic balance corrected, ensuring smooth operation, low vibration, and low noise (whole-unit noise ≤78dB) during 25,000rpm high-speed rotation. The device has a compact overall structure with small footprint, convenient installation, no complex foundation construction or lubrication system required, with extremely low maintenance costs. Our factory has decades of fan manufacturing experience, predecessor being the state-owned Shengxian Grain Machinery Factory, with deep technical accumulation in high-speed aeration blower design, permanent magnet motor assembly, and water treatment system integration, holding multiple aeration fan technology patents, producing 10,000 complete fan units monthly. Each High Pressure High Speed Aeration Blower undergoes full-speed operation testing, airflow and pressure performance testing, vibration testing, temperature rise testing, and dissolved oxygen system joint debugging testing before shipment, ensuring equipment performance meets standards. For overseas sewage treatment engineering contractors, environmental equipment integrators, aquaculture equipment dealers, and large farms, the High Pressure High Speed Aeration Blower is a high-efficiency, energy-saving, smart oxygen-control, low-maintenance aeration solution, suitable for key promotion in water treatment engineering, environmental equipment, aquaculture, and industrial support channels.
