Integrated fume extractor system advantages 

Intelligent control

The central fume purification system is controlled by PLC control system. All of operations control and information display are on the control panel with control button and display screen, the operation screen is humanization design and the operating is very convenient.

Our engineers can set the running program according to the requirement of different working conditions, for instance the automatically cleaning ash times after starting and stopping the equipment. Setting up the reverse blow cleaning’s technical parameters according to the on-site air environment, fume & dust characters and compressed air supplying.

The controlling system implements real time monitoring and analyzes on a number of important parameters of the equipment in operation, and show them on the display screen. It has automatically self-diagnosis function to show the equipment’s abnormal and error conditions in operation. These functions can make the equipment in good working condition and extend the usage life of the equipment.

Surface filtration precision

The functionality of an extractor lies in the filter cartridge’s material, Kaisen has been dedicating to upgrading filter cartridge.

Kaisen filter element is specially developed for the purification of fume and tiny particles generated in welding and cutting, which solved this industry’s problem of low filtration precision and filter element’s blocking. Kaisen filter cartridge uses polyester fibers (glass fiber) material, and with a special heat process the outer surface of the cartridge is covered with a layer of PTFE (polytetrafluorethylene) membrane. The filter cartridge’s interior wall is thin and firm, the surface membrane has very even pores, and form a network of pores’ of diameter less than 0.1μm.

In order to increase filtration area, all of filters are folded in “v” shape, the folding angle is sharp, so no dusts will be retained in the “V” shaped folds when the vertically placed filter cartridge is blow-cleaned. Dusts directly fall into the dust collector below and won’t cause interactive pollution.

Reverse blow cleaning

Rotary dust blowing device is inserted inside the filter cartridge and very close to the cartridge’s inner wall. When the solenoid valve opens, compressed air rush into two pipes drilled with nozzles, implementing rotary blowing to clean every part of the filter cartridge. Compared with externally placed blowing nozzles, rotary dust blowing nozzles’ blow force is even on every part of the cartridge, and have a thorough cleaning to avoid big noise and damage to the cartridge caused by instant huge blow impact of the externally placed blowing method.
