Low vacuum Industrial Dust Collectors vs. high vacuum Industrial Dust Collectors

What is the difference between low and high negative pressure dust/flue gas exhaust? What are their advantages?
Why do Industrial Dust Collectors need to exhaust welding smoke?
Smoke welding process is composed of solid particles, is the metal vapor condensation Many of these particles to contain the elements of lung disease Such as aluminum and titanium iron cause lung irritation and/or systemic poisoning (including copper lead manganese zinc nickel and) coating and base metal residue, or plasma cutting and laser cutting process will produce smoke Welders are particularly vulnerable to exposure to welding fumes. However, these fumes may also affect others through low or high vacuum exhaust. Effective capture of welding fumes at source greatly reduces the risk of particulate matter diffusing throughout the atmosphere
The advantages of low vacuum Industrial Dust Collectors
The suction arm is a kind of industrial dust removal equipment, usually used for low vacuum pumping. They remove large amounts of air at a lower rate, similar to the range hoods of a home stove. Many industrial processes, such as welding or cutting, produce hot smoke that rises naturally. The suction cover of the suction arm can be installed above the welding station, or placed across the welding table from the welder, so that the suction cover or nozzle is horizontal toward the source of smoke. The distance between the smoke source and the exhaust point provides more work space for the welder. Another benefit of low-vacuum industrial dust removal systems is that they can be used with tools that do not (or cannot) have an integrated drainage system. Return air tables, down-draft tables and hoods can also sometimes absorb harmful gases from welders, but require a large fan and therefore consume more energy than suction arms.
Advantages of high vacuum Industrial Dust Collectors
High vacuum industrial dust removal systems are commonly used to capture heavier particles operating at high speeds, such as dust from industrial processes such as grinding or sandblasting. However, high vacuum industrial dust removal equipment is also very effective for capturing smoke emissions from welding, especially when the suction arm is not always close enough to the smoke source. Nieman's kit incorporates suction and discharge devices into the torch to capture the fumes at source, preventing the welder from inhaling toxic gases. Another advantage of high-vacuum industrial dust catchers is that the suction and discharge units can be moved with the welder's movements, allowing greater freedom of operation and productivity.
Another advantage of high vacuum over low vacuum industrial precipitators is that it can also be used as a general cleaning system in a factory or workshop. The welder may use an industrial dust Extractor to exhaust the flue gas during welding, a grinding device with an integrated industrial dust extractor to grind and capture dust, or a high vacuum Industrial Dust Collector to clean the working environment.
Why capture the smoke at the source?
No matter low vacuum industrial dust removal equipment or high vacuum industrial dust removal equipment, there are several advantages to capture welding dust from the source:
Smaller flue gas exhaust points use smaller fans, thus reducing costs. Lower air volume means lower heating and air-conditioning costs.
Capturing the fumes at the source prevents welders and other workers from being exposed to harmful environments, thus providing a safer and healthier workplace.
Capturing the flue gas from the source also removes dust from the surface and interior of the equipment, facilitates routine cleaning, requires less cleaning and maintenance, and extends the service life of the machine.
Which Industrial Dust Collectors should I choose?
Deciding whether to use a low vacuum or high vacuum industrial dust removal system basically considers two key factors: installation space and welding process.
How much space does your ceiling have? In addition to mounting height, the low vacuum suction arm requires a clearance of 3-4 feet.
How big is your workspace? The length of the low vacuum suction arm can range from 3 to 16 feet. Bending the suction arm may limit its airflow.
Do you need to move your welding job all the time? If so, a drain kit may be the ideal choice.
Do you have a special welding space? If so, does it already contain several welding torches? (Ideally, integrated pumping and draining devices can be considered)
