Your birds are already stressed and if your poultry facility is hot, humid and filled with ammonia odors, your birds are stressed. The air quality directly affects feed conversion, egg production, and flock mortality rates. The answer is the appropriate Poultry Exhaust Fans for your broiler, layer and breeder raising facilities.
Marut Air manufactures heavy duty poultry exhaust fans specifically designed for the broiler, layer & breeder farm industry throughout India. Regardless of whether your poultry facility has 5,000 birds or has 5,000,000 birds, our Poultry Exhaust Fans provide the air quality required for your birds’ optimal performance.
Why Poultry Houses Need Dedicated Exhaust Fans
Why poultry facilities require dedicated exhaust fans
Standard industrial exhaust fans are not designed for the environment of a poultry facility. There are unique challenges inside a poultry facility.
- High levels of ammonia through the manure and litter corrode motor and fan blades not designed for ammonia.
- Debris, dust particles and feather particles clog up motors that do not have IP-rated protection.
- Continuous operations – Poultry exhaust fans run 18 to 24 hours a day and require high-efficiency motors that will not fail.
- Indian summers can regularly exceed 42 degrees Celsius in the poultry facility where there is not sufficient air flow.
A well designed poultry exhaust fan system is not optional, it is an essential tool farmers use to protect flock health and profitability.
What Do Poultry Exhaust Fans Actually Do?
A poultry exhaust fan replaces old, polluted air, with new clean air, to help maintain healthy conditions for the birds in poultry houses.
Here’s how poultry exhaust fans will help your poultry house:
- Remove Heat
Poultry exhaust fans will help to remove heat from birds, bedding material, and the sun to help keep the temperature within a comfortable range for broilers and layers.
- Ammonia & CO₂ Removal
The effect of poultry exhaust fans on the removal of harmful gases, such as ammonia, and carbon dioxide, will help maintain the health of your birds through their air supply.
- Humidity Control
Poultry exhaust fans will assist in keeping the moisture content from being high enough to promote wet litter and diseases.
- Dust Removal
Poultry exhaust fans remove dust, feathers, and feed particles from the air, improving the air quality and overall healthiness of the birds.
- Uniform Air Distribution
Poultry exhaust fans will ensure that the air is moving uniformly throughout the poultry house so that there are no areas where heat or gases can accumulate.
Types of Poultry Exhaust Fans – Which One Does Your Farm Need?
Many types of poultry fan systems exist to support agriculture, not all poultry fans fit all farms. Here are the three major poultry fan types offered by Marut Air and how they are utilized:
- Axial Poultry Exhaust Fan
These are the most common types of fans because they provide a high capacity of air circulation required to maintain a low pressure environment.
Best Used In: Open-sided broiler barns, small layer houses and mounted to the sidewalls.
- Tunnel Ventilation Fan
These exhaust fans produce a directional and concentrated air stream to enhance cooling effects to both operators and animals (even when the ambient temperature exceeds 97°F).
Best Used In: Closed/somewhat closed poultry houses, larger poultry farms and between tunnel ventilation systems.
- Variable Speed Poultry Exhaust Fan
These fans vary their speed to match a predetermined level of performance as atmospheric conditions change, thus maximising system efficiency by reducing energy consumption.
Best Used In: Poultry farms that have automated systems as well as those that want to minimise the amount of electricity consumed.
Ventilation Systems Using Poultry Exhaust Fans — Tunnel vs. Cross Ventilation
When choosing the right fan, it is also crucial to understand which ventilation system is right:
|
Feature |
Cross Ventilation |
Tunnel Ventilation |
|
Air Direction |
Side to side (width) |
End to end (length) |
|
Fan Placement |
Side walls |
End wall (exhaust end) |
|
Best House Width |
Up to 40 feet |
40 to 60+ feet |
|
Bird Density |
Low to medium |
Medium to high |
|
Heat Stress Control |
Moderate |
Excellent |
|
Fan Type Recommended |
Axial poultry exhaust fans |
High velocity cone fans |
What Happens When Poultry Exhaust Fans Fail or Are Undersized?
|
Condition Inside Shed |
What You See in Birds |
|
Temperature above 30°C |
Panting, wing spreading & water consumption spikes |
|
Ammonia above 25 ppm |
Watery eyes, coughing and high condemnation rates at slaughter |
|
Relative humidity above 75% |
Wet litter, footpad lesions, coccidiosis outbreaks |
|
CO₂ above 3,000 ppm |
Lethargy, reduced feed intake and FCR deterioration |
|
Poor air circulation |
Uneven flock growth, mortality clustering in certain areas |
These are production and profitability losses that may occur and most can be prevented with correctly sized and maintained poultry exhaust fans.
How to Calculate the Right Poultry Exhaust Fan Capacity for Your Farm
The most important factor in sizing exhaust fans for poultry houses is the ultimate capacity of your exhaust fans. If your fans are undersized, then the birds won’t get the proper protection from the temperatures during the summer months. Conversely, if your fans are oversized, you will waste energy and put extreme cold stress on your birds during the winter months.
The following are basic CFM calculations by season for Broiler Houses:
- Hot, summer peaks: 4 to 5 CFM per bird
- Moderate: 1 to 2 CFM per bird
- Cold, winter minimum: 0.1 to 0.5 CFM per bird
Example; using a 25,000 bird Broiler House for peak summer ventilation you would require:
- Summer peak is 25,000 birds x 4.5 CFM per bird = 112,500 CFM.
- If you have fans with 36,000 CFM each you would require at least 3 to 4 large tunnel fans for your summer peak.

Every 3 months |
|
Check and tighten belt tension (belt driven models) |
Every 3 months |
|
Lubricate motor bearings |
Every 6 months |
|
Inspect motor wiring and connections |
Every 6 months |
|
Check shutter/louver operation |
Monthly |
|
Full inspection and replace worn parts |

Frequently Asked Questions About Poultry Exhaust Fans
- How many Poultry Exhaust fans are required for my shed?
To decide how many fans you will need for your shed, you will need to consider the size of the shed, how many birds are being held in the shed and the type of ventilation being used in the shed. For example, a 400 ft shed containing 25000 birds may require around 3 to 4 large fans to cool the shed down during the summer season. It is always best to get a calculation from an expert for your farm. “
- What is the difference between a 36 inch Poultry Exhaust fan and a 54 inch Poultry Exhaust fan?
36-inch diameter fans can be used for smaller sheds or as an added source of ventilation in a larger shed while 54-inch diameter fans produce more air flow than the 36-inch fans and are used to ventilate larger commercial farms that have tunnel ventilation.
- Can Poultry Exhaust fans be used during the winter months?
Yes. However, they should only be used in a short-cycle mode to help move moisture and other harmful gases from the building without over-cooling the shed.
- How often should Poultry Exhaust fans be cleaned?
Once every three months, although, if you are operating in a dustier farm, cleaning fans at least once a month would be best to maintain a proper airflow.
- How long will Poultry Exhaust fans last for?
With proper maintenance, these fans can last anywhere from six years to ten years. Many spare parts and services are readily available for these fans.
- Is it worth purchasing energy efficient Poultry Exhaust fans?
Yes, due to the fact that they consume less electric power and can provide significant long-term savings on your electric bill. This is especially true for larger farms where you operate several fans.
