negative pressure ventilator and Push pull negative pressure fan

There are generally two types of negative pressure fans in aquaculture farms, one is a square negative pressure fan with a galvanized sheet shell, and the other is a horn shaped anti-corrosion negative pressure fan. Introduction to negative pressure fans used in factory workshops

Features: The price of galvanized sheet shell is relatively cheap, while the horn shaped fiberglass shell is relatively expensive, but it can prevent corrosion.

1、 What are the advantages of negative pressure fans.

1. What are the advantages of negative pressure fans? Ventilation and ventilation in the workshop is one of them:

The negative pressure fan drives away the stuffy workshop through large air volume, belonging to a category of fans. Each fan has at least several thousand to tens of thousands or even hundreds of thousands of large exhaust air volumes. Using a large air volume negative pressure fan in a large workshop has a good ventilation effect.

2. What are the advantages of negative pressure fans? Users should be able to experience cooling:

Negative pressure fan is a physical ventilation cooling device that solves the problem of high ambient temperature caused by lack of air circulation in the environment.

3. What are the advantages of negative pressure fans? We pay attention to discharging smoke and odor:

What is a negative pressure fan? The negative pressure fan solves the problem of welding fume accumulation in the workshop while providing ventilation, and introduces more fresh air to the workshop. Introduction to negative pressure fans used in factory workshops

4. What are the advantages and wide range of use of negative pressure fans

Various places with dense crowds, large heat sources, or prone to pollution, high temperatures, muggy heat, smoke, odor, dust, and other poorly ventilated areas can exert significant effects.

2、 Working principle of negative pressure fan

The working principle of the negative pressure fan is mainly based on the principles of air convection, negative pressure ventilation, and air exchange and cooling. This working principle of the negative pressure fan is conducive to ventilation and cooling. It is a machine that naturally sucks in fresh air from the opposite direction of the installation site – the door or window, and quickly forces indoor hot gases out of the room. Any poor ventilation problem can result in a cooling and air exchange effect of over 94, without occupying workshop space. For factory and workshop use

Animal husbandry specialized negative pressure fan for cooling and ventilation equipment

Important measures for circulating ventilation, cooling and consumption reduction in livestock and poultry houses. The hot summer climate often causes many adverse effects on the breeding industry. When the temperature of the livestock and poultry breeding environment is continuously above 32 ℃ -34 ℃, there is usually a significant decrease in appetite, an increase in body temperature, lethargy, unknown high fever, decreased reproductive performance, and other changes. In severe cases, death may occur. Therefore, in order to reduce the impact of high temperature and humidity on livestock and poultry, effective and reasonable scientific measures must be taken to reduce the losses caused by aquaculture production. At present, in the animal husbandry industry, negative pressure fans utilize the working principle of air convection and negative pressure ventilation, which can effectively solve the problem of high temperature and stuffiness. Below, the editor will provide a detailed introduction to the ventilation principle of animal husbandry fans.

Animal husbandry expels air outward, causing a decrease in indoor air pressure and thinning of indoor air. The characteristics of animal husbandry form a negative pressure zone, and air flows into the room due to pressure difference compensation. In practical applications in industrial factories, animal husbandry is installed centrally on one side of the factory building, with an air inlet on the other side of the factory building. The air flows from the air inlet to the animal husbandry fan to form convective blowing. During this process, the doors and windows near the livestock fan remain closed, forcing air to flow into the workshop through the compensation of the air inlet side doors and windows. The air flows into the workshop in an orderly manner from the intake, flows through the workshop, and is discharged from the workshop by a livestock fan. Thorough and efficient ventilation, with a ventilation rate of up to 99%. Through specific engineering design, designing air exchange rates and wind speeds as needed, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problem can be completely solved at once. Ventilation can be achieved within a few seconds of turning on the fan.
