What are ventilation accessories for air ventilation in ventilation systems and ventilation systems with a non-return valve
Ventilation accessories are special devices that are an integral part of any ventilation system. Their main function is to ensure effective ventilation, stable air exchange, and an optimal indoor microclimate. These elements include ventilation grilles, diffusers, non-return valves, exhaust fans, and other components of the ventilation system.
Ventilation grilles are installed at the inlets and outlets of air ducts. They help direct the airflow and perform an aesthetic function in the building. Diffusers allow air to be evenly distributed throughout rooms, improving comfort and the stability of temperature and humidity.
Valves play an important role in protecting ventilation systems. In particular, the non-return valve prevents air from entering in the reverse direction, protecting the ventilation system from unwanted odors or dust from the exhaust. All these devices are installed in accordance with technical parameters, pressure, flow rate, and design nuances.
During installation, the type of duct, type of fan, supply or exhaust functions, system features, and the ventilation needs of specific premises are taken into account. Quality fans, units, ventilation systems, properly selected ventilation valves, and other elements help optimize ventilation in any environment.

Ventilation grilles in ventilation systems: features of ventilation systems, types of ventilation grilles, and their role in air ventilation
Ventilation grilles are an important element of a ventilation system that affects air quality, air exchange, airflow, and the effectiveness of room ventilation. Without a properly selected grille, ventilation will be insufficiently productive, and comfort and residents’ health depend on ventilation.
Depending on the type of ventilation (for example, mechanical ventilation, natural ventilation, or supply-and-exhaust ventilation with heat recovery), different ventilation systems and elements of the ventilation system are used. The required ventilation is provided by a fan, exhaust fans, and air moving through ducts that manage supply and exhaust air.
Main types of ventilation grilles:
- Supply grilles — supply fresh air into the room;
- Exhaust grilles — remove polluted air;
- Non-return valves — prevent reverse airflow and cold air entering from outside;
- Decorative grilles — combine functionality and aesthetics.
Materials used for ventilation grilles:
- Plastic — lightweight, corrosion resistant;
- Aluminum — strong and light;
- Steel — durable, used for industrial systems.
Ventilation grilles are installed in ducts, at air inlets and outlets, to effectively control airflow and maintain optimal parameters of air temperature, pressure, and humidity. They help maintain a healthy indoor microclimate, protect against dust, and ensure normal air exchange.
In modern ventilation systems with heat recovery, it is important to correctly select grilles to control supply air and maintain comfortable indoor conditions.
Diffusers in the ventilation system: features of air ventilation, air distribution in ventilation systems and mechanical ventilation, and the ventilation system
Diffusers are an important device in a ventilation system, responsible for the even distribution of air in a room. They ensure comfortable air exchange and help maintain optimal air temperature and proper indoor air parameters.
In mechanical ventilation systems using axial or centrifugal fans, diffusers help regulate air flow and direct the airflow to avoid stagnant zones and ensure high-quality air ventilation. They also play a role in regulating the airflow that enters the room from outside air or returns from it.
One nuance is the use of diffusers in systems with heat recovery, where it is necessary not only to supply fresh air but also to effectively remove exhaust air. In such systems, a non-return valve is often installed to prevent reverse flow and the penetration of cold outdoor air, which helps retain heat and reduce energy costs.
Diffusers provide the distribution of warm air or fresh air according to specified parameters, improving the microclimate and preventing excessive humidity or dust indoors. They are a key element of supply and exhaust fans that ensure high-quality room ventilation.
Thus, without proper installation and selection of diffusers, ventilation will be insufficiently effective, which negatively affects the comfort and health of people in the building.
One effective way to organize high-quality ventilation in rooms is to use powerful supply-and-exhaust units. For example:
- Vents PR 900×500 — a reliable high-capacity ventilation unit that provides stable air exchange and maintains a comfortable microclimate in spacious rooms or offices.
- Vents PR 150 G-4 — a compact yet efficient device for ventilating small rooms; it combines high performance with the ability to adjust airflow.
Non-return valves in a ventilation system: how a non-return valve works in air ventilation, features of reverse airflow in ventilation systems
Non-return valves are an important element of a ventilation system that prevents reverse airflow. They are installed in ventilation ducts to control airflow and maintain high-quality air ventilation indoors. The use of a non-return valve is especially relevant in systems with exhaust ventilation, where air extraction is carried out using axial or centrifugal fans.
The main principle of operation of a non-return valve is that it allows air to pass in only one direction — from the room to the outside, preventing outside air from entering back into the system. This is very important for maintaining optimal air temperature and retaining warm air inside the building. A non-return valve also helps prevent dust and unwanted odors from entering from the ventilation ducts.
An important nuance is that the design of the valve must be selected taking into account air flow rate and the features of the specific ventilation system. If the valve is installed incorrectly or is absent, ventilation will be insufficient, and this will worsen indoor air quality, affecting the microclimate.
In systems with heat recovery, non-return valves also help regulate airflow and save the energy spent on heating the air. They are an integral part of modern ventilation systems that ensure effective air exchange and comfort in buildings.
Tips for choosing a ventilation system: non-return valve, features of valves for ventilation systems, mechanical ventilation, and air ventilation
Tips on selecting and placing ventilation devices must take into account the main nuances of how a ventilation system works. The correct choice of fan, in particular an axial or centrifugal fan, is key to ensuring high-quality room ventilation. It is important to consider air flow rate so that the system operates efficiently and provides sufficient air exchange.
When choosing a fan, you should focus on current air parameters, air temperature, and the type of ventilation: mechanical, exhaust, or a system with heat recovery. Fans must meet the required parameters to maintain a comfortable microclimate, taking into account warm air and its airflow regulation. Ventilation is a system that operates on the basis of balanced movement of outdoor and indoor air.
As for placement, attention should be paid to installing devices in such a way as to ensure optimal air exchange — supplying fresh outdoor air and removing indoor air through exhausts. In systems with a non-return valve, it is important to place valves on ducts to prevent air from entering back, maintaining indoor air temperature and air quality.
Also consider:
- Distance from heat and dust sources for high-quality ventilation.
- The possibility of connecting to systems with heat recovery to save energy.
- Providing access for servicing the fan and valves.
- Considering airflow direction to prevent mixing indoor air with outside air.

Most common mistakes during installation of a ventilation system: non-return valve, air ventilation, ventilation systems, and features of the ventilation system
Proper installation is the foundation of the effective operation of any ventilation system. However, equipment installation often involves typical mistakes that reduce efficiency, increase air flow rate, and hinder maintaining stable air temperature. This affects comfort, energy costs, and the overall performance of the fan.
Most common mistakes:
- Incorrectly calculated air flow rate — leads to insufficient air exchange or system overload.
- Incorrectly selected fan — the type or power does not meet the needs for air from the room.
- Installing a fan without taking into account air resistance in ducts or without pressure compensation.
- Using low-quality or unsuitable equipment for exhaust ventilation, making it difficult to remove warm air.
- Lack of filters to remove dust from the air, which worsens the condition of the system.
- Violation of design requirements when installing a system with heat recovery, reducing its efficiency.
- Ignoring the technical characteristics of axial or centrifugal fans, which prevents achieving high-quality ventilation.
- Incorrectly configured air supply modes for heating during the winter period.
To avoid these mistakes, installation should be entrusted only to professionals. This will ensure stable operation of the ventilation system, retention of warm air indoors, and effective air purification from dust, which is especially important for residential and commercial facilities.
