In-line duct fans
In-line duct fans
This category includes duct fans of VO, VOK, and MT-VO series designed for installation on air ducts of ventilation, air conditioning and heating systems.
Series VO-T, VOK-T and VK-200 heat-resistant channel fans are presented separately in the corresponding section.
VO series fans are designed for installation on air ducts with the following cross-sections: Ø90, Ø96, Ø100, Ø120, Ø135, and Ø150.
VOK series fans are designed for installation on air ducts with the following cross-sections: Ø100, Ø110, Ø120, Ø135 и Ø150.
MT-VO series fans are designed for installation on air ducts with the following cross-sections: Ø90, Ø100 и Ø120.
The MT-VO duct fans have low noise level and are made of high quality and non-toxic materials; they meet fire safety standards.
The level of protection of in-built electric engine — IP 24 — allows the fan to work normally under the conditions of high humidity. They can also be customized with check valve. They are mainly used in amenity spaces with the temperature of up to +40°С.
The VO and VOK fans are equipped with an in-built noiseless and hermetically sealed electric engine including two-capsule bearings produced by a Japanese company, NSK, which is guaranteed to work for 30000 hours without any flows if installed horizontally or vertically. The purpose of their use is cooling the air flow with the temperature of up to +60°С. The level of protection of in-built electric engine — IP 44 — allows the fan to work normally under the conditions of high humidity.
The enclosure, the turbine, and the check valve are made of aluminium alloy or glass-nylon composite, which guarantees effective cooling and better fire safety.
Additional options and accessories:
All VO and VOK fans can be made to work with 60 Hz frequency without any substantial changes in other characteristics.
If the air flow needs to be regulated, the fan can be controlled with a speed regulator (dimmer).
VOK models with mounting holes with the diameters of 100 mm, 120 mm, and 150 mm can be additionally equipped with the following:
- mounting bracket
- check valve preventing cold air and insects from entering the room if the fan is turned off
