Product catalog summary

Overview
Duct fans, specifically the WKO series, are designed for ventilation systems due to their simple construction, ease of assembly, and cost-effectiveness. They combine the benefits of axial and radial fans, maintaining axial airflow while overcoming significant installation resistances. These fans operate with low noise emissions.

Intended Use
WKO duct fans are suitable for intake and exhaust ventilation in industrial and general building engineering. They can handle air polluted with vapors and corrosive gases within environmental protection limits.

Device Description
The WKO series includes six fan sizes. Each fan consists of a plastic casing with connecting spouts and a high-efficiency plastic centrifugal impeller with an internal motor.

Working Conditions
These fans can operate in any position, with a maximum permissible air temperature of 50°C.

Designations
The WKO series includes sizes 10, 12.5, 16, 20, 25, and 31.5.

Technical Data

WKO-10: Ød 100 mm, ØD 255 mm, Weight 5.5 kg
WKO-12.5: Ød 125 mm, ØD 255 mm, Weight 5.5 kg
WKO-16: Ød 160 mm, ØD 345 mm, Weight 7 kg
WKO-20: Ød 200 mm, ØD 340 mm, Weight 8 kg
WKO-25: Ød 250 mm, ØD 340 mm, Weight 8 kg
WKO-31.5: Ød 315 mm, ØD 405 mm, Weight 9.5 kg

Motor Specifications
Each fan type is equipped with a specific motor model, operating at 1~230 V with varying power and current ratings, and rotational speeds ranging from 2250 to 2510 rpm.

Noise Levels
Noise levels vary by fan size, with acoustic energy directed to the duct and acoustic pressure levels measured at a 1m distance. For example, the WKO-10 has a noise level of 64 dB(A) directed to the duct and 47 dB(A) in the fan environment.

Catalog excerpts

DUCT FANS КАНАЛЬНЫЕ ВЕНТИЛЯТОРЫ Duct fans are really useful solution in many ventilation installations because of their easy construction, easy assembly and the low costs of construction and operation. They connect the advantages of axial and radial fans because they keep the axial air flow direction with the possibility of overcome the bigger installation resistances. WKO fans operation is characterized by the low volume emitted to the environment. INTENDED USE Duct fans are designed for use them in the intake and exhaust ventilating installations made in the industrial and general building engineering. Flowing air can be polluted with the vapors and corrosive gases and polluted with the gases within the limits which are permitted by the environment protection regulations. Применение канальных вентиляторов является оптимальным решением во многих вентсистемах благодаря их простой конструкции, легкому монтажу и следовательно небольшим затратам на их монтаж и эксплуатацию. Канальные вентиляторы объединяют в себе преимущества осевых и центробежных вентиляторов, так как обеспечивают осевое направление потока воздуха с возможностью преодоления значительного сопротивления вентсистемы. Работа вентилятора WKO характеризуется низким уровнем шума, воздействующим на окружающую среду. ПРИМЕНЕНИЕ Канальные вентиляторы предназначены для применения в приточных и вытяжных вентсистемах на объектах промышленного и общего назначения. Воздух, проходящий через вентилятор, может содержать пар, пыль и коррозионные газы в пределах, допустимых нормами охраны окружающей среды. DEVICE DESCRIPTION Series of types of fans include 6 dimensions. Fans consist in: ›› casing made of plastic with the connecting spout to the ventilating installations ›› highly efficient plastic c
