Plasma Cutting Fume Extractors 1. Product description: Moland provides both dust collectors for plasma cutting fume extraction entire fume extraction system with dust collector and ducts. The common ways are one side suction type, two sides suction type and hood suction type. 2. Moland Product Series Portable Fume Extractor series contain of MLWF50, MLWF70, MLWF100, MLWF360, MLWF120, MLWF200, MLWF280-basic, MLWF280S, MLWF290, MLWF300, MLWF300A, MLWF350, MLWF350D, MLWF400, etc. Stationary fume extractors (MLWF350-dust bucket type, MLWF500-6T, MLWF500-6T dust bucket type, MLWF500-9T, MLWF800, MLWF800-dust bucket type, MLWF1000, MLWF1500, MLWF2000, MLWF3000, MLWF3500, MLWF4000). The electric control cabinet can be seperated from main equipment for convenient operation when the main equipment is placed outdoors. Grinding dust extractors are our another dust extraction product series, which contain of downdraft table (MLWF100D, MLWF150D, MLWF200D, MLWF320-DM, MLWF180, MLWF380, MLWF480) and grinding cabinet (MLWF900). The grinding cabinet is usally equipped with telescopic or fixed grinding room, to form a semi-closed space to control dust and smoke spread. It also improves the filtration efficiency with low air volume and energy consumption. 3. R&D In order to provide advanced products, our R&D department develops 3 to 5 new products every year, and irregularly improves the performance, appearance, and installation methods of existing products. 4. Certification All our products are approved by CE, ISO9001, ISO14001, utility model patent, design patent, Program copyright, etc. 5. Exhibition Moland participates at least 5 industry exhibitions each year. 6. Central Fume Extraction System 1) Cantilever type fume extraction system Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the Suction Hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better. 2) Hood suction type fume extraction system Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the suction hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better. 3) Room tupe fume extraction system Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing. For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean. The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals. 4) Blow suction type fume extraction system Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops. 7.
