VENTS - manufacture of ventilation and air conditioning systems

Inline centrifugal fan VENTS VKP mini series

Inline centrifugal fan VENTS VKP mini series

Compact centrifugal fans in steel casing with the air capacity up to 176 m3/h with permanent air flow maintenaning at alternating pressure in the system. Designed for supply and exhaust ventilation systems.


Description

Applications

Supply and exhaust ventilation systems for various small premises with a limited mounting space. For connection with Ø 80 and 100 mm round ducts. Various casing modifications with the number of inlets from 1 to 6 enable using one fan for air exhaust from several premises simultaneously. This makes ventilation system mounting much easier.

Design

The fan casing is made of steel with polymeric coating. The casing height is only 94 mm for VKP…80 model and 112 mm for VKP…100 model that enables fan mounting in a limited space. The removable cover provides free access to the motor, ensures easy mounting and enables the fan and air ducts maintenance without dismounting.

Motor

The centrifugal impeller with backward curved blades for high pressure is powered by means of the single-phase three-speed motor with external rotor. The custom designed «SMART» turbine construction (motor and impeller) provides constant airflow support in the premise and simultaneous motor speed control as a function of air resistance in the duct.

Motor is equipped with incorporated overheating protection with automatic restart and ball bearings for long service life designed for at least 40 000 hours. For precise features, safe operation and low noise, each turbine is dynamically balanced while assembly. Motor protection rating IP 44.

Speed control

The motor speed changes automatically as a function of ventilation system resistance thus ensuring the constant air flow. For smooth or step speed control a thyristor or autotransformer controller can be applied. Motor speed changes automatically as a function of the ventilation system resistance. This ensures constant airflow. If a three-position switch is additionally installed, three speeds of motor can be controlled manually.

Several fans can be connected to one controller in case the total power and operating current do not exceed the controller rated values.

Mounting

Mounting at any angle to the wall is performed with the fastening bracket supplied with the unit. The fan is powered through the external terminal box.

Electric connection and mounting shall be performed in compliance with the manual and wiring diagram on the terminal box.
