50 inch double door type ventilation fan

1. Fan double doors closed with the rubber sealing which effectively avoid air backflow when start fans at different time. Greatly improve the operation efficency by 15-20% compared with the same power fan.

2. Muhe fan blade is special designed for top grade efficiency which made of Krupp stainless steel by punch forming. Large air volume, no deformation, no broken, no dust, attractive and durable Thickness 1.2mm, surface finish BA grade.

3. Reasonable cone designing which can concentrate blowing and direction, so the air flow is bigger and the fan will be energy-efficient, lower noise.
Characteristics of poultry ventilation fan butterfly cone fan

4. Reasonable cone design with huge air volume.
II. High-strength,low noise and long service life.
III. Shutters are made of high-strength PVC,oxidation resisting,light weight and have no distortions.
IV. High-strength dabber aluminium magnesium alloy wheel.
V. 6 blades with mirror designed and the stainless steel with injection moulding, large air volume,never distortion, and never broken.

5.Brief Descriptions of poultry ventilation fan butterfly cone fan
I.This kind of cone fan has larger capacity.
II.Huger air flow and higher efficiency are its distinct features.
III.It has some advantages like large air volume, low noise,energy saving,and steady running,etc
IV.9FJ-E series cone fan has overall performance superior to 9FJA/B ventilation fans.
V.They have much larger air volume and higher working efficiency than the ordinary exhaust fans.
VI.CE certificate.

6.Advantages of poultry ventilation fan butterfly cone fan
I. Negative pressure ventilating fan series are designed scientifically.
II. Low cost, low noise, good ventilation effect, strong air flow, energy saving, long lasting and high efficiency.
III. The parts with stainless steel have waterproof and dustproof effects.
IV. By pumping the air with negative pressure, the fan circulates the air indoor and outdoor, and drives out the heat in the workshop.
