What is Air Filter?
Air filter also called air purifiers, it is a device for suck the smoke, fume, smell or tiny particles. Thus avoid harm for human body and avoid environment pollution. During use of our laser cutting machine or Laser Marking Machine, there always some fume and tiny particles come out, so a air filter is important for operator and environment.

On March 30, 2011, Cummins took its four European V environmental power and four European IV and National IV products to the debut at the 2011 Shanghai World Bus Expo Asia Exhibition. Cummins's participating passenger car engines include the ISF 3.8 liter, ISB 6.7 liter, ISL 8.9 liter, ISM11 liter and ISZ13 liter eight products, power coverage 107-550 hp, displacement covers light, medium and heavy series. In addition to the imported ISB and ISL, two European V-powered engines, the ISF 3.8-litre and ISM 11-liter engines produced by Foton Cummins and Xi'an Cummins have also passed the European V certification successively, becoming an important support for the domestic passenger car companies to further expand their overseas markets. power. 
The Foton Cummins ISF 3.8-liter engine is an innovative future-oriented product developed by Cummins' advanced technology development experience. It covers 141-168 hp and is an ideal power for 6-8-meter buses. The ISF structure is streamlined, which is 40% less than the number of engine parts in the same class and is easy to maintain. An average of 500,000 kilometers long overhaul mileage, 20,000 kilometers maintenance intervals, low maintenance costs. This lightweight power product is small, lightweight, low fuel consumption, and has the best fuel economy in its class. ISF was fully prepared for the upgrade of Euro V emission standards at the beginning of development and has now become China's first batch of light engine products that have achieved Euro V certification. Within just over a year of entering the market, ISF has partnered with domestic passenger car manufacturers Foton, Yutong, Suzhou Golden Dragon and Xiamen Golden Brigade, and successfully entered overseas markets such as Europe, Australia, Singapore, Russia, and Brazil. The ISF, which was favored by the market, won the Power Award in the selection of the Bus Components Expo held recently. 
The ISM 11-liter engine is the Cummins heavy-duty flagship powertrain that began operation in Xi'an Cummins in 2007, with a power range of 345-440 hp. Based on Euro III and Euro IV, under the circumstance of GM's main components, the Euro V can be easily upgraded with stable fuel consumption and emissions. Lower. The ISM 11-liter engine integrates Cummins' global R&D capabilities and is highly reliable. It possesses excellent qualities such as low-speed torque, strong heavy-lift start-up capability, fast acceleration on flat roads, and high speed of climbing without deceleration. Using the world's most mature braking system, the braking power is up to 326 horsepower, which significantly reduces the braking distance while reducing brake pad wear. With OBD vehicle diagnostic system, real-time monitoring of operating conditions. The Cummins ISM 11-liter engine has a global holding of more than 500,000 units, has been verified by the 450 billion kilometers without major overhaul, and is stable and remarkable. It is the first choice for large buses. 
The Cummins ISB 6.7-liter fully electronically controlled engine (185-300 hp) is a proven classic model in the international and domestic markets, with unparalleled reliability and durability, and its global engine base B-Series product holds more than 700 Million Taiwan, ISB sales in Europe more than 100,000 units. While adhering to the superior power and cycle operating cost advantages of the Euro IV product platform, the ISB 6.7 engine further enhances the engine's fuel economy, reduces noise and emissions, and creates greater profitability for users worldwide. . On the eve of the Spring Festival, the first batch of Beijing Bus Ecobuses loaded with the Cummins ISB 6.7-liter Euro 5 emission engine was formally put into operation. This is also the first batch of Euro V power products that have been verified in the international market for domestic bus markets. 
As a global leader in environmental power technology, Cummins has always taken the lead in bringing to the market engine products that meet the strictest emissions regulations. In 2007, Cummins first introduced a series of engines that meet Euro V emission standards to the global market. Up to now, the global sales of Cummins Euro V engine products have exceeded 20,000 units. The Euro V emission standards require that the emission of nitrogen oxides (NOx) and particulate matter (PM) be reduced to 2 grams per kilowatt-hour and 0.02 grams per kilowatt-hour respectively, and that the nitrogen oxide emissions are reduced by more than 40% compared with the previous phase. Cummins uses in-cylinder combustion optimization and selective catalytic reduction (SCR) to meet Euro V emission standards. SCR technology can bring better fuel economy, longer maintenance intervals, and higher reliability to the engine.
Since 2009, Cummins Europe V products have been matched with China's major OEMs, and have become a “stepping stone†for the top domestic passenger car plants to reach the international high-end market. In addition, Cummins' distribution service network in more than 190 countries and regions around the world also provides strong pre-sales, in-sale, and after-sales full-cycle support for Chinese bus companies' overseas strategy.
