Ventilation and Purification

Ventilation fan driven by an electric motor rotates the air blades to drive the airflow, so that indoor and outdoor air exchange of a class of air conditioning appliances. Also known as ventilation fan. The purpose of the internal ventilation fan is to remove the indoor dirty air, adjust the temperature, humidity and achieve the effect of air circulation. Ventilair fan is widely used in homes and public places.

There are three main customer demands for fans in the field of ventilation: Energy efficiency, adaptive self-regulation control ability according to load changes, and flexibility to meet the variety of application needs of customers.

Blauberg as an industry leader in air purification fan fans and motors, offers a complete range of axial flow fans and motors for ventilation.

Traditionally, AC motor is usually used as fan impeller driving device that have many advantages of EC technology are becoming more and more difficult to ignore. Over KW three-phase AC asynchronous motor has satisfactory efficiency in full loading operation, but the efficiency of single-phase or less than KW three-phase motor cannot meet the requirements. AC motors also need to use frequency converters to control speed, which will cause power loss, and additional filtering is required to protect sensitive motor bearings. Using frequency converter to drive asynchronous motor with partial load often produces noise, which makes the motor hum.

Blauberg EC(Electronically Commutated) motor adopted DC brushless circuit engine driving principle. It has integrated electronics controller that is convenience to be controlled at maximum efficiency up to 90%. The EC motor could quietly rotate, even if it is operating no at full-loading performance point. Ventilation and purification industries commonly request that fans and relative products that could be controlled by integrated electronic device and manipulated by software program, besides wireless access necessary.

Solutions for Ventilation and Purification

It makes BLAUBERG to be air ventilation and air purification industries priority fan supplier by our constant concentration on aerodynamic engineering system creative solution to decrease customers’ operating and maintaining cost. Our EC motor power goes up to maxim 1320W that could drive axial and centrifugal impeller to maximum diameter 710mm. According customer’s technology requirements that EC motors software program could drive fans at constant speed, constant airflow by closed-loop feedback system circuit setting, with optional outside connecting devices, such as, integrated PID controller, thermal speed control sensor with power supply and RS485 Modbus interface for remote refresh, updating program and diagnosis.

By comparing the actual operation and maintenance costs in entire indoor ventilation fan life cycle, it is concluded that our commercial automatic ventilation fan can ideally meet the market requirements as appropriate solutions for air ventilation.

Automatic Ventilation Fans

for Air Purification and Ventilation in Commercial and Industrial Environments

The ventilair fan is characterized by low investment cost, large air volume, low noise, low energy consumption, smooth operation, long life and high efficiency.

Indoor ventilation fans are classified according to the form of airflow:

  • Centrifugal: air enters from a direction parallel to the axis of rotation and exits perpendicular to the direction of the axis.

  • Axial flow type: air enters from a direction parallel to the axis of rotation and exits still parallel to the direction of the axis.

  • Cross-flow type: air enters and exits perpendicular to the direction of the shaft.
