What is a Gravity Relief Ventilator?

Have you ever heard of a gravity relief ventilator (GRV) and wondered what it does? A GRV is a device that is used in buildings to create ventilation. It works by allowing outside air to be drawn into the building’s internal space, and then expelled out at the same rate. GRVs are particularly useful for buildings located in areas which are prone to high levels of air pollution or which contain hazardous substances. In this blog post, we will explore what a gravity relief ventilator is, how it works, and why it may be necessary for certain types of buildings. Let’s dive in!

What is a Gravity Relief Ventilator?

A gravity relief ventilator is a type of natural ventilation that uses the force of gravity to help move air through a building. The vents are typically located near the top of a building and allow hot air to rise and escape while cooler air is pulled in from lower openings. Gravity relief ventilators are most effective in tall buildings with little or no wind.

How Does a Gravity Relief Ventilator Work?

A gravity relief ventilator is a device that uses the natural force of gravity to help ventilate a space. The device consists of a fan and a weighted damper that are mounted on the ceiling of a room. The fan pulls air into the room while the damper automatically closes when the airflow reaches a certain level, preventing the room from becoming too pressurized.

Advantages of a Gravity Relief Ventilator

A gravity relief ventilator is a type of mechanical ventilation that uses the force of gravity to help move air in and out of the lungs. The advantage of this type of ventilator over other types is that it requires less energy to operate, which can be important in a hospital setting where power may be limited. Additionally, gravity relief ventilators are less likely to cause patient discomfort than other types of mechanical ventilation.

Disadvantages of a Gravity Relief Ventilator

There are several disadvantages of a gravity relief ventilator. One is that they can be loud, which can be disruptive to both the patients and staff. Additionally, they require regular maintenance and can be difficult to clean. They also may not work well in high humidity environments.

Conclusion

Gravity Relief Ventilators are a great way to provide ventilation for large spaces. They are ideal for industrial, commercial and residential applications, as they are energy efficient and cost effective. The installation process is relatively easy and can be done in no time. With the right maintenance and inspection schedule, these ventilators can ensure that your space is properly ventilated at all times while saving you money on energy costs.
