Ventilation grilles with louver

Ventilation grilles with blinds are an important element of the ventilation system. The main function of ventilation grilles is to regulate air flow in the room and protect against insects, dust, small debris and bird feathers. These elements are decorative and can mask ventilation openings, giving them an aesthetic appearance. The design of ventilation grilles is equipped with fixed slats or movable louver elements. The movable ones open under air pressure or from the operation of a motor (fan).

On the VADA website, you can purchase high-quality ventilation grilles with louvers that ensure the efficient operation of the entire ventilation system. After all, maintaining the microclimate in rooms where animals or birds are kept is necessary to ensure their health, productivity, and prevent the spread of infections. The task of high-quality ventilation is to remove harmful gases such as ammonia and carbon dioxide, eliminate excessive humidity and excess heat. It is ventilation equipment for poultry houses, cowsheds and piggeries that provides the optimal level of oxygen for animals and birds. The most comfortable conditions are created in the room, which prevents the reproduction of various pathogens and microbes.

What are ventilation grilles with blinds

A ventilation system is extremely important in rooms where cattle, pigs or poultry are kept. In a sealed and insulated poultry house or pigsty without proper ventilation, unpleasant odours, harmful gases and excess moisture are immediately trapped. In such an environment, microorganisms begin to multiply intensively, causing infections and various diseases in animals and poultry.

Ventilation equipment for piggeries and poultry houses is equipped with ventilation grilles with blinds. A grille is a device that is mounted directly in the ventilation inlet or ventilation duct. The blinds on the grilles perform a protective function. These elements are necessary for regulating and protecting the system, and also serve a decorative purpose.

The main functions of the grilles are:

• control of air inflow and outflow;
• protection from draughts, rain and debris;
• aesthetic design of openings in walls.

This important functional ventilation detail can be made in two versions: with fixed slats and louvers (movable). The difference between them is the method of air flow control. Fixed louvers provide a constant air flow direction, while adjustable louvers allow you to change the air direction or block it completely.

Movable ventilation louvers without an automated drive are activated by natural factors. Fresh air enters due to the difference in wind pressure and internal temperature. Forced opening/closing occurs by connecting fans that can be turned on manually or automatically using special sensors.

Large automated ventilation grilles can be additionally protected with sturdy mesh. This protection is effective against the intrusion of wild animals and birds when the grilles are open. Modern models are also equipped with light filters to block direct sunlight.

Types of ventilation grilles with blinds

Depending on the materials used in their manufacture, ventilation grilles are divided into the following main types:

• plastic — lightweight, durable, designed for indoor use;
• metal — provide reliable protection, often available as automated models;
• aluminium — compact and lightweight, resistant to external influences.

There are manual models and automatic options with controls. Metal louvered grilles designed for greenhouses, cowsheds, etc. are equipped with drives for automated opening/closing. In some models, all dampers open at once, and in others, they open individually.

The special feature of louvered grilles for industrial farms is that they are designed for high throughput. Ventilation systems in large rooms are designed to handle a significant volume of air. Such equipment for large cowsheds, piggeries and poultry houses is operated in intensive mode. The larger the livestock population in a single room, the more significant the emissions of gases, vapours and moisture that need to be removed.

Both natural and mechanical forced ventilation systems must be equipped with the appropriate type of grilles. For effective operation, automatic dampers and movable blinds are often combined in the system.

How to choose ventilation grilles with blinds

Ventilation systems are relevant on farms, as well as in industrial production and in large rooms with a large flow of people. Therefore, automated modern grilles are in high demand. Without specially designed air vents, the entire system loses its efficiency: the removal of harmful emissions deteriorates, humidity indicators are disrupted, and the oxygen level in the room decreases.

Ventilation grilles are an essential component of a general ventilation system. Without this element, dirt, dust, debris, and atmospheric precipitation enter the openings, creating draughts that are harmful to animals. When choosing ventilation grilles, the following basic criteria should be taken into account:

• size;
• material of manufacture;
• method of installation;
• compatibility of the grilles with the ventilation system.

The choice for small and large farms will differ. For small spaces, compact models with movable slats that perform protective and regulatory functions are sufficient.

Large industrial-scale cowsheds, piggeries and poultry houses are usually equipped with combined ventilation systems. This type requires internal, external and current air distributors. It also requires ventilation grilles with natural and mechanical regulation.

Modern systems are equipped with complex automation, to which all ventilation grilles are connected. Temperature and humidity sensors measure the indicators in the room and send a signal to open/close the blinds of the ventilation grilles. Proper installation with the selection of appropriate ventilation grilles allows you to comply with sanitary standards for keeping animals and birds on farms.
