When you stand in front of a fan, you feel the breeze metres away; the expelled air travels in a steady jet. With suction, however, the situation is exactly the opposite: the suction inlet draws in air from all directions (from the front, the sides, and partly from the rear) simultaneously. The air comes not from a single corridor, but from the entire spherical volume surrounding the inlet. For this reason, the suction velocity drops dramatically as you move away from the inl

Every fan has a characteristic curve. The horizontal axis represents the flow rate, and the vertical axis represents the pressure the fan can generate. The two ends of the curve show two extreme conditions. • The bottom right shows the free blowing point. Pressure is zero, flow rate is highest. • The top left shows the opposite. The highest pressure the fan can generate as the flow rate approaches zero. While operating, the fan is somewhere on this curve. The fan alone canno

The Difference Between ePTFE Membrane Cartridges and Classic Cartridges.

Welding fume separation classes are defined in the ISO 21904 standard series, which is currently in effect. (Formerly known as EN ISO 15012 — many still refer to it by this number in the market; it's an earlier version of the same family.)

Laser engraving, coding and marking are indispensable parts of modern production. But these precision processes have a by-product: Potentially harmful fumes and particles. Effectively filtering these fumes is critical not only for worker health, but also for equipment life, product quality and environmental compliance.

A composite material is a combination of two materials with different physical and chemical properties. When combined, they form a material that is specialised to do a specific job, for example to be stronger, lighter or resistant to electricity. They can also increase strength and stiffness. The reason for their use compared to conventional materials is that they improve the properties of their base material and are applicable in many situations.

According to the International Federation of Robotics (IFR) data, the number of industrial robots in operation increased from 3 million 904 thousand in 2022 to 4 million 282 thousand in 2023.

There are many substances harmful to health in the smoke generated during the welding process. Welding fume contains heavy metals. In welding and cutting processes, various gases are produced as a result of the combustion or evaporation of welding consumables, cutting fluid on the main material welded, residues such as oil, grease and coatings such as paint, galvanising with the effect of arc temperature.

Welding joins metal parts with intense heat, to which consumable electrodes are often applied to improve the assembly of larger parts. Smoke is emitted from the base metal and especially from the electrodes. Welding fume is a complex mixture of metals, gases and other compounds. It also contains very small particles, including ultrafine matter. The exposure of welders depends on several factors, including the welding process itself, workplace characteristics and protective me
