Purpose, design, and types of anemostats
In every home with ventilation, the ventilation duct opening is covered with a grille or diffuser. This final element of the engineering system serves a decorative purpose and protects the duct from debris and rodent intrusion.
The incoming air flows are distributed through the grille or diffuser, but their volume cannot be regulated.
An anemostat performs a similar function, but has a control mechanism with an air valve. The user can adjust the amount of air supplied by sliding the disc along the screw. When closed, the valve prevents air from flowing.
While the grille is typically rectangular, the anemostat is always cylindrical. It comes with a flange and coupling for mounting on a wall, ceiling, or duct. This technical product is used in ventilation, air conditioning, and air heating systems.
The primary classification of anemostats is based on the valve design. The shape of the valve plate determines which direction the airflow is directed.
According to the material they are made from, anemostats are classified as plastic, metal and with a wooden plateThe devices are different. diameter, air valve stroke sizeThe supply and exhaust models typically have one valve. A universal unit can be designed with two valves.
Models with a diameter of 80-100 mm are suitable for small rooms. For larger spaces, units with a diameter of 125-200 mm are used.
Models are selected based on their air flow capacity, taking into account the ventilation system's design parameters. Now that we have some basic information about anemometers and what they are, we can begin reviewing the ratings.

Step-by-step guide to installing an anemostat
Installing the air diffuser yourself will take no more than half an hour. The most difficult part of the installation is cutting a round hole for the device body.
You'll need a drill with a hole saw appropriate for the material you'll be working with. Additionally, be sure to have a screwdriver, pliers, and a marking tool handy.
Let's consider an example of installing an adjustable anemostat in a chipboard box:
- Unpack the anemostat and familiarize yourself with its contents. Check for the presence of mounting hardware. Measure the housing diameter, which will require cutting the mounting socket.
- Check the valve's travel. Check how tightly the valve disc fits into the seat in the closed position.
- Remove the auxiliary mounting flange from the housing. This part will be needed to secure the anemostat to the box.
- By pressing your fingers on the valve mechanism from the inside, remove the working unit from the cylindrical body.
- Prepare a wood hole saw for drilling a hole in the chipboard frame. The bit diameter should match the size of the appliance being installed.
- Mark the area on the box where the hole needs to be made. Drill the mounting hole using a drill with a hole saw. The valve body has a main flange with holes for screw mounting. If this mounting option is suitable, have the hardware and a screwdriver ready.
- Place the enclosure inside the cut-out opening. Attach the main flange to the chipboard with screws, if this mounting option is available.
- If screw mounting isn't an option, secure the housing in the socket with an auxiliary flange. Place the shaped piece onto the sleeve from the inside of the box.
- Insert the valve operating mechanism into the fixed housing.
This completes the anemostat installation. Test the mechanism and adjust the valve. Follow the same procedure for installing anemostats on suspended ceilings and drywall walls.

Answers to current questions
An anemostat is considered the best in operation due to the ability to regulate the air flow.
A supply and exhaust valve is a universal device that operates on both the exhaust and supply air ducts. The valve can handle both incoming and outgoing air flows.
The diffuser can be rectangular or round in shape and is installed instead of the grille on the ventilation opening in the room.
The device seals the duct from contamination and rodent intrusion, serves a decorative function, and diffuses airflow. Unlike a grille, a diffuser can be equipped with a static pressure chamber and an impeller.
Depending on the material they are made from, anemostats can be made of plastic, metal, or with a wooden plate.
Based on installation location, these are exhaust, supply, and universal supply-and-exhaust models. These units vary in diameter and have one or two valve plates.
