Vacuum cleaner filtration
Vacuum cleaner filtration
Dust bag filtration
Filtering out 99.99% of particles as small as 0.3 microns, the vacuum cleaner using the dust bag will decrease in vacuum as time goes by, resulting in less suction, and it is impossible for the user to replace it every time it is used. Dust bags, so microorganisms such as mites will continue to grow in the dust bag, and these mites will cause secondary pollution to the surrounding environment when cleaning the dust bag. The dust bag is used as a filter feature, which is easy to clean and does not need to be cleaned every day. It is suitable for the factory hotel car beauty cleaning industry. The disadvantage is that the time is long, the filtering capacity of the dust bag is reduced, the pores of the cloth will open, the filtering capacity is seriously reduced, and it needs to be replaced.
Dust cup filtration
The dust cup filter separates garbage and gas through the vacuum airflow rotating at high speed of the motor, and then filters the material through HEPA to purify the air to avoid secondary pollution. The advantage is that the dust bag does not need to be replaced frequently; the disadvantage is that it is cleaned after the vacuum is completed.
Water filtration
The use of water as a filter medium allows most of the dust and microorganisms to be dissolved and locked in the water as they pass through, and the rest is filtered through the filter and further filtered so that the exhaust gas from the vacuum cleaner may be cleaner than the air when inhaled.
The filtration effect of the water filter vacuum cleaner is unquestionable, but because it uses water as the filter medium, it puts higher requirements on the design of the product itself and the waterproof protection of the motor. This is why the quality of the water filter vacuum cleaner on the market is uneven, and the price is very high. The important reason. Characteristics: The suction is more remarkable, and the discharged gas is purified by water. Disadvantages: Water needs to be drained every time it is used. After use, it must be cleaned. If it is not clean, it will be mildew, smell and rust. Suitable for: hotel home office and more. [
Precision Optical Flats are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20. Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.
Silicon features a Knoop Hardness of 1150 and low density, making it tougher than germanium substrates and suitable for weight-sensitive applications, respectively. Diamond-Like Carbon (DLC) Coated Silicon Windows are engineered for 3 to 5µm, making them ideal for infrared defense applications such as thermal imaging.
Diamond-Like Carbon (DLC) Coated Silicon Windows provide anti-reflection coating on one surface and a specially designed DLC coating on the other surface, making these windows highly durable and ideal for harsh environments.
