High Temperature High Speed Centrifugal Fan

This High Temperature High Speed Centrifugal Fan, developed for high-temperature gas conveying scenarios, is a high-speed centrifugal ventilation device capable of continuous stable operation in high-temperature environments. In industrial production, many processstages generate high-temperature gases, such as boiler flue gas, industrial furnace hot air, drying equipment exhaust gas, and heat treatment furnace flue gas, where ordinary fans develop problems such as motor overheating and burnout, bearing lubrication failure, and impeller thermal deformation in high-temperature environments, unable to operate reliably long-term. Our High Temperature High Speed Centrifugal Fan uses dedicated high-temperature-resistant design, capable of continuous stable operation in medium temperatures up to 250°C (400°C for special customization), widely applicable to high-temperature ventilation scenarios such as boiler induced draft, industrial furnace flue gas conveying, drying equipment hot air circulation, and heat treatment furnace exhaust. The device uses a high-speed centrifugal impeller design with maximum speed up to 8,000rpm, maximum airflow up to 8,000m³/h, and maximum pressure up to 15kPa, efficiently conveying high-temperature gases and overcoming system resistance.

For high-temperature-resistant structural design, this High Temperature High Speed Centrifugal Fan has undergone systematic high-temperature protection design from impeller, volute, and bearings to motor. Impellers use high-temperature-resistant stainless steel material (304/310S optional), undergoing high-temperature aging treatment and precision dynamic balance correction to ensure no deformation and low vibration at high temperatures. The volute uses a double-layer water-cooled jacket structure (standard for high-temperature models), with cooling water circulating in the jacket tocarry away heat, protecting volute housing temperature from exceeding 60°C while reducing bearing housing temperature. The bearing housing uses water-cooled or air-cooled structure paired with high-temperature-resistant grease, ensuring long-term stable bearing operation in high-temperature environments. The motor and fan are connected via an extended coupling, with the motoraway from the high-temperature gas source to avoid high-temperature radiationimpact, and the motor is equipped with an independent cooling fan. The device is equipped with a smart temperature control system, real-time monitoring bearing and motor temperatures, automatically alarming or shutting down for protection when over-temperature. Our factory has decades of industrial fan manufacturing experience, predecessor being the state-owned Shengxian Grain Machinery Factory, with deep technical accumulation in high-temperature fan design, high-temperature material processing, and industrial fan system integration, holding multiple high-temperature fan technology patents, producing 10,000 complete fan units monthly. Each High Temperature High Speed Centrifugal Fan undergoes high-temperature simulation testing, full-speed operation testing, airflow and pressure performance testing, vibration testing, and temperature rise testing before shipment, ensuring stable and reliable equipment operation in high-temperature environments. For overseas boiler manufacturers, industrial furnace manufacturers, drying equipment enterprises, and environmental engineering contractors, the High Temperature High Speed Centrifugal Fan is a professional and reliable high-temperature gas conveying solution, suitable for key promotion in industrial support, environmental engineering, and thermal equipment channels.

We have an independent R&D team supporting full-range customization of high-temperature high-speed centrifugal fans. Customers can provide working condition parameters (medium temperature, medium composition, airflow, pressure, installation method, etc.), and we complete custom solutions and samples within 15 working days. Customizable content includes: temperature resistance grade (250°C/350°C/400°C optional), airflow and pressure specifications (1000-30000m³/h, 5-30kPa range), impeller material (304/316/310S / high-temperature-resistant alloy), volute cooling method (water cooling / air cooling / no cooling), motor power and brand, inlet/outlet flange dimensions and direction, installation method (vertical / horizontal / belt drive / direct drive), and anti-corrosion coating (for corrosive high-temperature gases). MOQ is 100 units, with small-batch project trial orders supported.

We are ISO9000 quality management system certified and have established a dedicated quality inspection process for high-temperature fan products. Each High Temperature High Speed Centrifugal Fan undergoes before shipment: high-temperature simulation operation test (verifying temperature resistance in a high-temperature test chamber), full-speed operation aging test (no less than 4 hours), standard performance test bench verification of airflow and pressure curves, vibration test (G2.5 grade dynamic balance), bearing and motor temperature rise test, water cooling system sealing test, and electrical safety test. Impeller materials have undergone material spectral analysis verification, and welding has undergone non-destructive testing. We accept third-party inspection and can cooperate with agencies such as SGS, BV, and TUV for pre-shipment inspection.

Standard payment terms are 50% advance deposit + 50% balance settled before shipment. Custom products follow the same process: 50% advance, 50% balance after production completion, then buyer pickup. Large-volume orders enjoy tiered discount pricing, with lower unit prices for larger order quantities. We accept settlement in USD and RMB, and can issue VAT special invoices. Repeat-order customers enjoy faster delivery, and long-term cooperation customers can apply for more flexible payment terms. Industrial project products can be delivered in batches based on project progress.
