Pigs are commonly group housed in a air-compact space. They are sensitive to draughts and have limited thermoregulation ability; they need a proper living environment in the scorching weather that impairs their health and production. So ventilation systems for confined swine operations are important in order to keep a desirable environmental conditions inside of the pig barns.
Ventilation is necessary to prevent a build-up of microbes, dust and exhaled air in pig barns. It is also needed to remove excess humidity and heat. The ventilation of swine farms should be performed not only in summer, also in winter. But, winter ventilation rates are considerably lower than summer ventilation rates. The primary function of ventilation in winter is moisture removal and the primary function of ventilation in summer is heat removal. Excess heat from animals in summer must be removed on a continuous basis to maintain the optimum animal performance.
Exhaust fans are typically used in the ventilation system of pig barns, and the FRP (Fiber Reinforced Plastic) fan is a negative-pressure ventilating equipment. FRP fan is a kind of mechanical ventilation system widely used for pig farming.

FRP Fan Can Complete Ventilation through Negative Pressure
The FRP fan forces the hot air in the pig barn outside, so the indoor pressure is lowered, forming an negative-pressure zone, and the outdoor fresh air flows into the pig house for the air pressure difference. Negative pressure causes the air exchange between indoor and outdoor to complete supporting good air quality which not only improves pig health, performance and welfare but also reduces emission of greenhouse gases, odours and dust to the environment, and creating the proper temperature at which pigs feel comfortable in hot days.
At the sane time, the FRP fan can be also used with evaporative cooling pads to realize an optimum ventilating-cooling effect.
FRP Fan Has a Wide Application
As a new-type ventilation equipment made of anti-corrosion FRP, FRP fan is featured by corrosion resistance, high air delivery rate, low power consumption, low noise, etc. So it widely used for many places.
1.For ventilating and cooling animal farms, such as pig farms, cattle farms, chicken farms, etc.
2.For labor-intensive enterprises: clothing factories, various assembly work shops, etc.
3.For workshops with high temperature and foreign smell: thermal treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather product plants, plating factories, and various chemical plants.
4.For the place that needs cooling as well as a certain humidity, like the textile plants, including cotton mills, woolen mills, flax mills, weaving factories, chemical fiber plants, warp knitting factories, texturing plants, knitwear mills, silk mills, and sock factories, etc.
5.For the ventilation and cooling of horticultural greenhouses.
6.Available for the field of warehouse logistics.
7.For ventilating and air exhausting of office buildings, marketplaces, theaters, hospitals, workshops and basements, etc.
The FRP negative-pressure fan can be installed in the window or on the roof, but the installation in the window has better ventilation and cooling results.
How to Choose Good-performance FRP Fan for Pig Farms
1.Air exhausting issues: air exhausting rate is an important parameter indicating the ventilating-cooling effect of FRP negative-pressure fan. It is expressed as the volume of air movement per unit time and its standard unit is cubic feet per minute (cfm). Under the condition of the same power consumption and specification, the fan with higher air exhausting rate has better ventilating-cooling effect.
2.Power issues: as mentioned above, the working performance of the FRP negative-pressure fan is a result of its air exhausting rate, so high power does not mean good ventilating-cooling effect, and high power can increase the electricity waste and investment cost.
3.Cooling issues: it is important to note that the FRP negative-pressure fan has no refrigeration function, and it completes pig farm ventilating and cooling through air convection and air exchange caused by negative pressure.
