Blowers and Vacuum Pumps

Blowers and Vacuum Pumps

Blowers are devices that usually operate with an electric motor and provide the air required for an environment or process. It is possible to see these devices, which are also used for vacuuming according to the method of use and connection type, directly or indirectly in almost all areas of the industry. Successful, stable and long-term blowers are generally used as centrifugal blower models in every application that requires high air flow.

The blower types include roots blowers and oily vacuum pumps, as well as devices that operate on the principle of centrifuge or side channel blower. According to the application type, environmental conditions and needs, blowers can be selected from the standard models, and special productions can be provided upon request.

Blower Types and Working Principles

A typical blower operates by an electric motor and the movement of a fan or lobe attached to the shaft of this motor. As a result of the high speed rotation of the motor, therefore the shaft connected to the shaft, a vacuum is formed at the inlet part of the blower and the air in the environment is taken inside. This air is then directed to the outlet by centrifugal movement and transferred to the relevant place.

Centrifugal blower, which is one of the most preferred models among blower types, can be used horizontally or vertically and with different line accessories and also called as side channel Blower. Among the most important features of the centrifugal blowers are the advantages of silent operation, high efficiency, oil-free operation, simple and compact design, easy installation and quick commissioning.

Roots blower devices are also distinguished from centrifugal blower models with the feature of operating with belt-pulley principle and as a positive displacement blower, that is, in short, not affected by pressure changes due to speed. These models, which have a lubricated cast steel body on both sides, are long-lasting blowers and feature silent operation.

The most important feature of the models that fall into the oily vacuum pump category is that they are air cooled and injected. Electric motors, oil separators, vibration damping feet and check valves are supplied as standard in these models, which are used successfully in blower types such as packaging, machinery, molds, medicine, etc. that require vacuum.

What Should Be Considered When Choosing Blower?

The blower selection stage has a critical place in order for a process requiring blower to be successful and to provide high efficiency. In the selection of the blower, which requires different criteria according to the type of application and usage area, the following issues should be considered briefly:

Air flow required for the environment or process

Pressure loss value corresponding to this air flow in the installation on which the blower is installed

If vacuuming is to be carried out, the vacuum pressure value required

Ambient temperature, associated extract air temperature

Air flow direction (for the decision of vacuum or pressure application)

Relative humidity value

Altitude value

Other equipment to be used with blower; air ducts, filters, solenoid and check valves, vibration dampers, pressure gauge, thermometer or other sensors

Details on the installation of the blower; connection principle, installation type and equipment

Application; If it requires a special design due to high temperature, corrosivity, humidity, wind, flammability and similar critical factors, the selection of blowers should be made in accordance with these factors.
