What does high vacuum mean?
For example; The vacuum cleaners in our homes are high vacuum systems. In these systems, the air flow rate is lower but the pressure is very high. In these systems, blower systems are used instead of radial fans. When point smoke and dust suction is required, high vacuum systems should be used. Thanks to the blower rotating at very high speeds, very high pressures can be achieved.

Why do I need high vacuum units for industrial smoke and dust extraction?
To give an example for welding fume; When smoke suction via torch is preferred, a high vacuum unit must be used. Each torch manufacturer may have different values ​​due to design. In general, a flow rate of at least 55 m³/hour and a pressure of 3000 pascals will be required.
When point suction is required in many processes such as grinding, soldering, laser marking, the solution is a suitable high vacuum system.

Can multiple people use these systems at the same time?
Manufacturers design and produce systems that can be used by one person, two people, four people and even 20 people at the same time. For example; 4 fume extraction welding torches can be connected to our Avevo OTEX-1500 unit and used at the same time.

What type should the blower be?
There are blower types such as brushed, brushless DC and brushless EC. Brush (coal) type blowers may be less durable. In addition, frequent brush changes are required. However, you can choose products using this type of blower as it will be more economical for semi-professional or amateur use.
For products using EC blowers, there is no need for additional equipment, for example for speed adjustment. Many functions can be performed through the EC system and less energy consumption can be achieved.

Should the flow rate increase automatically as the filter fills?
It would be more beneficial to get this type of machine. Machines that produce constant constant flow are available on the market. However, as the filter fills, the flow rate decreases. When you get an electronically controlled high vacuum unit, the machine constantly keeps the flow rate constant. Until the filter reaches its full saturation point.
