Overall dimensions of duct fan 315 mm

315 mm duct fan is a productive and reliable equipment designed for installation in supply and exhaust ventilation systems. The device parameters make it possible to effectively service large and medium-sized commercial, industrial and domestic premises.

Duct fan 315 (VK) is manufactured in metal and plastic versions and can be installed horizontally or vertically.

Round duct fan 315 can have several designs. In addition to the standard version, manufacturing plants also offer a silent version, high- and low-power engines, and models with lower energy consumption. The price for such modifications is slightly higher compared to standard samples.

Electric motor in duct fans and thermal protection

The centrifugal fan is equipped with a single-phase motor. The equipment is designed for connection to standard voltage networks. The design of the working element contributes to increased device performance. So the VKK wheel is equipped with backward-curved blades.

One of the undeniable advantages of the products is absolute safety during operation. The engines of all models are equipped with built-in thermal protection, which leads to shutdown when the maximum permissible temperatures are reached. After the threat has passed, the main elements have cooled down and are ready for further use, the devices automatically restart.

The design of electric motors involves the use of rolling bearings. These parts significantly increase the number of cycles of equipment use, increasing its service life to more than 40 thousand hours.

The devices are designed for continuous operation, so regularly restarting them can lead to premature wear of the working elements.

VKK electric motors have a degree of protection IP 44. This means that they are protected from splashes of water and small solid particles entering with the air.

Manufacturing plants produce several modifications of electric motors for this type of equipment. Each variety has its own label:

Other symbols in the model names may indicate the type of speed control and equipment.

Fans of this size are capable of serving larger areas compared to smaller diameter units such as the Tube 250 XL. You can buy equipment not only for use in city apartments and country cottages, but also for installation in restaurants, shops, warehouse office and industrial premises.

Assembly and main elements

The exhaust fan consists directly of the housing and the main working element. The shell can be made of galvanized steel or high-quality plastic.

The balanced engine wheel is equipped with curved blades. This feature allows the devices to achieve maximum safety and quietness with increased performance. The motor winding contains thermal contacts, which are the main components of the thermal protection system. Their reliability determines how promptly the device will stop working if it overheats.

The design of the models may differ significantly. Some products are equipped with a plug and power cord, a terminal box, and various types of fasteners and sensors.

An important component of the VK is the speed control system. Performance is set by controlling the incoming voltage. Devices may use transformers or seven-storage regulators.

Depending on the method of speed control, devices are divided into:

Several products can be connected to one regulator, but their total parameters should not exceed the nominal values ​​of the element.

Installation and connection of fans for round ducts Vents VKMts

Installation of the Vents VKMts fan is permissible at any angle. Installing the fan at any angle does not affect its performance. The fan is mounted to a wall or any building structure using brackets.

The power connection occurs through the mounting box installed on the fan housing. The electrical connection diagram is available in the installation box and in the technical data sheet for the Vents VKMts fan.

Application

Universal devices can be installed on all types of surfaces inside and outside buildings. In cases where premises have special requirements in the field of noise characteristics, one or more noise suppressors can be added to the system, improving the fan’s performance at any part of the frequency range.

Duct fan 315, Analogs

Round duct fans (VKK) are used in various supply and exhaust ventilation systems to move non-explosive air mixtures at temperatures from -15 to +60 °C. Installed directly into a round duct (air duct) vertically or horizontally. Duct fans for round ducts equipped with an impeller with backward curved blades, an electric motor with an external rotor, and built-in thermal contacts. Protection class of electric motors is IP44. Manufactured in accordance with TU 4861-006-03002146-2016.

Duct fans are produced in standard sizes corresponding to the internal diameters of round ventilation ducts: VKK-100, VKK-125, VKK-160, VKK-200, VKK-250, VKK-315, VKK-355, VKK-400, where the numbers indicate the internal diameter of the duct in mm.

Round duct fans are manufactured in four versions:

- in a plastic case (VKK)

- in a galvanized metal case, with mounting bracket (VKK-M)

terms of Use

Round duct fans VKK designed for moving non-explosive air and gas environments with temperatures from -40°C to +40°C, containing solid impurities of no more than 100 mg/m3, not containing sticky substances and fibrous materials, in temperate climate conditions of the 2nd category of placement according to GOST 15150 -69.

To reduce losses associated with air flow turbulence, straight sections of air duct should be located at the inlet and outlet of the fan.
The minimum recommended length for these straight runs is one fan diameter on the inlet side and three fan diameters on the outlet side.

The suction duct must not have any obstacles to the air flow (dampers, branches, etc.).
