Product Details
This DPF series Single-flow Ventilation Fan is a high-efficiency, low-noise ventilation device designed for indoor air exchange scenarios, combining quiet operation, high-efficiency air supply, and long-lasting durability to meet diverse ventilation needs in both residential and commercial spaces.
Featuring special sound-absorbing materials and non-vortex blades, the fan operates at a minimum noise level of only 28dB(A), effectively eliminating noise disturbance. Optimized with an Archimedean spiral volute, asymmetric multi-blade impeller, and precisely matched volute tongue and impeller, it delivers a 30% efficiency improvement over traditional fans. The overall positioning processing technology significantly boosts static pressure, enabling long-distance air supply. Constructed with thickened galvanized steel plate via integrated die processing, the fan ensures excellent corrosion resistance and structural stability, and supports dual-speed adjustment to suit different scenarios with flexible high/low speed switching.
Powered by 220V single-phase supply, the DPF series includes 8 models with air flow ranging from 150-1200m³/h, maximum static pressure from 75-370Pa, power from 32-270W, and net weight from 9.0-22.4kg. Flange sizes cover Φ150-Φ250, with overall dimensions from 350×350×270mm to 520×450×380mm, allowing flexible adaptation to installation and ventilation requirements of different spaces. It is an efficient, quiet, and durable ventilation solution.
