Economical Airflow for High-Volume Ventilation

The Low-Pressure High-Temperature Fan is an essential, cost-effective ventilation solution designed for high-volume, low-resistance movement of hot gases. Bridging the gap between standard low-pressure fans and medium-pressure high-temperature models, it excels in applications such as food and timber drying, greenhouse heating, low-level chemical exhaust, and paint line pre-drying. With a lightweight, universal design, this efficient product is ideal for a wide range of small- to medium-scale commercial and industrial thermal ventilation needs.

Streamlined & Purpose-Built Construction

Featuring simplified axial-flow or backward-curved centrifugal designs, this fan emphasizes essential heat-resistant treatment without complex pressure or cooling systems. Impeller materials are selected based on temperature: Q235 heat-resistant steel for ≤250°C, or 1Cr18Ni9Ti stainless steel for 250°C–350°C, followed by stress relief. The casing is a single-layer heat-resistant steel plate, sometimes with basic internal insulation. A straightforward, air-cooled bearing housing with optimized fins manages thermal loads, while a single-side positioning bearing accommodates shaft expansion. This no-fuss design makes the durable Low-Pressure High-Temperature Fan exceptionally reliable and low-maintenance.

Optimized for Efficient Thermal Circulation

Purpose-built to deliver large air volumes at low pressure with minimal energy consumption, the Low-Pressure High-Temperature Fan is at the heart of efficient drying and heating loops. Its performance range supports flexible and economical system design.
