Applications
VK fans are applied for supply and exhaust ventilation systems of commercial, office and other premises. Compatible with Ø 100, 125, 150, 200, 250 and 315 mm round air ducts. Models marked VK...Q are supplied with quiet motors for low-noise applications. Due to the corrosion-resistant durable plastic casing, these models are the perfect solution for the installation in exhaust ventilation systems in humid premises such as bathrooms, kitchens etc.
Design
The casing is made of high-quality durable ABS plastic. The fans are equipped with a waterproof terminal box. Models marked VK..R are supplied with the power cord and a plug.
Motor
The impeller with forward curved blades is powered by a single-phase asynchronous AC motor with external rotor including the following features:
- A dynamic balanced impeller with backward curved blades balanced in two planes.
- Overheating protection with automatic restart.
- Maintenance-free ball-bearings used with motors and designed for at least 40 000 hours operation. Models marked VKS are supplied with high-powered motors. Motor protection class IP 44.
Speed control
Smooth or stepped speed control can be performed by external thymistor or transformer.
Several fans can be connected to one speed controller if the total power and operating current of fans do not exceed the rated controller values.
Mounting
Instalation to the wall or ceiling can be performed by means of mounting brackets (included in the delivery) or with additional PVC holders (available upon request). The fan can be mounted at any angle. Electric connection and installation shall be performed in compliance with the manual and the wiring diagram on the terminal box.
Automatic speed control module
VK..U1 and VK..U1n are the perfect solution for greenhouses and other premises requiring air temperature control. These models are fitted with an integrated electronic speed control module TSC with temperature sensor that provides automatic speed regulation as a function of air temperature in the duct (VK..U1 with integrated temperature sensor) or directly in the ventilated area (VK..U1n with external sensor).
Temperature and minimum speed can be adjusted with two control knobs on the controller panel.
The external temperature sensor (in VK..Un and VK..U1n models) is supplied with 4 m cable and a protecting cover against mechanical damage. The LED indicator for thermostat operation is placed at the front panel of the fan.Automatic speed controller pattern for VK fans
Set points for the maximum air temperature and the fan speed are manually adjusted by the control knobs. Normally the fan operates with the speed which is set by the knob. If the temperature exceeds the set point, the fan boosts to the maximum speed. After that when the temperature drops down below the set point, the fan goes back to preset speed. The switching delay disables frequent motor switching if the set temperature in the duct is equal to the threshold temperature.
There are two patters of delay that may be used in various cases:
- Temperature sensor delay (VK…U): if the temperature rises by 2°С above the set thermostat operating threshold the motor switches to the increased speed. The motor switches to the preset (low) speed as the temperature drops below the set threshold. This pattern can be used to keep air temperature to within 2°С. In this case the fan switches are rare.
- Timer delay (VK…U1): the motor sets to higher speed 5 min after the temperature exceeds the set threshold . The motor switches to the preset (low) speed 5 min. after the temperature drops below the set threshold. This pattern can be used to keep the air temperature at a precise level. In this case the fan switches more frequently than in the pattern of temperature sensor delay, but the intervals do not exceed 5 minutes.
