The electric actuator for ventilation is designed to control the air flow in the ventilation duct. The actuator is mounted on the air damper valve shaft, i.e. choke using the included mounting kit. There are several basic types of electric actuators: standard and spring return.

The main manufacturers of electric drives are Gruner, Belimo, Polar Bear, Siemens and Lufberg.

6. With high moisture protection class IP66/67.

Consider the types of drives in more detail.

Standard actuators for ventilation

When used in an electric ventilation system, a standard electric ventilation actuator can be used or an electric drive without a return spring, and when using a duct water heater, it is necessary to use an electric drive with a return spring or a drive with a built-in capacitor with a protective emergency function. The use of such drives is necessary to prevent the penetration of cold, street air into the channel, and further freezing of the heat exchanger, in case of an emergency power outage.

Standard electric drive for ventilation or an actuator without a return spring will leave the channel damper in the open state in the event of a power outage, i.e. at the original location.

With return spring (with protective function)

In an actuator with a return spring, mechanical energy is accumulated (spring charging) during the rotation of the damper to the operating position, and the accumulated energy is released for emergency closing.

With built-in capacitor (with protective function)

An alternative to the standard spring return actuator is the more expensive and functional actuator with built-in capacitor. When such a drive is connected to the electrical network, an accumulation occurs, the accumulation of an electric charge necessary for closing air valve. Electric drive for ventilation with a condenser allows you to adjust the position of the damper in any required position, these can be extreme or intermediate points.

The air damper actuator is available with a variety of rotational forces, which are selected according to the cross-sectional area, air flow velocity and density of the damper seal.

The actuator for air damper ventilation is available with a 24 V or 220 V connection, depending on the use of the controller.

Positioner

For remote control of an electric drive with an analog signal from 0-10 V, apply positioners. Three types are available: built-in, surface-mounted, for mounting on a DIN rail.

Our company sells electric drives for ventilation not only in Moscow, the region, and throughout Russia.

Before you buy an air damper actuator used in ventilation and air conditioning systems, you need to know the device of the damper itself, or as it is also called, the throttle valve. This part of the air duct is specially designed for correcting and necessary air separation in the ventilation ducts.

With the help of dampers, both the entire ventilation system (air conditioning system) and its elements are controlled and adjusted.

Air throttle device

The design of this locking and regulating mechanism consists of a frame that follows the contour of the duct section (round or rectangular). It has a rotary axis, to which a blade is attached, capable of blocking the entire channel, or several parallel blades, each of which has its own axis. One of the ends of the rotary axis goes out through the side edge of the frame. To this end, the air damper valve actuator is connected, which can be:

• electromagnetic;
• Pneumatic;
• hydraulic;
• Manual (simple handle).

The frame is built into the channel as a separate shaped element in the form of a flange or superimposed (if the walls of the channel are flat) like a grid. Turning the axis regulates the closing and opening of the channel.

When the damper resembles a blind-like device in its appearance, it has not one rotary axis, but several. Each of them is brought out by one of the ends to the outside, and all are connected to a common thrust.

Varieties of air dampers

The price of the actuator for the air damper is directly where it is planned to be installed. In turn, throttle valves are divided into groups:

• Air shutters - for ventilation of warehouses, industrial premises and other household facilities. Operate at temperatures not exceeding 80 0 C, pressures up to 1500Pa;
• Fire dampers are fire-retarding, permanently open, and smoke, permanently closed;
• Explosion-proof - work in explosive rooms. The design of such a damper eliminates sparking during the operating cycle;
• Unified - the most popular, used in air conditioning and ventilation ducts of ordinary civil premises.

Varieties of actuators for dampers

Having become acquainted with the characteristics of air equipment, it becomes clear that a special actuator is needed for each specific damper.

You can buy a Siemens drive in St. Petersburg by choosing the appropriate one for a particular case:

• Mechanical with a manual drive, with a rotary axis equipped with a handle. It is marked with the letter P, it is used extremely rarely;
• Electric throttle valve - on its body there is a servo drive that drives the rotary axis. Usually installed in large ducts. Marking - the letter E;
• Pneumatic dampers.

Apart from this, Siemens actuators are divided into.
