Reference implementation of welding plant exhaust technology using G&G JET BAG filtration equipment of our production. In welding shop extraction applications we guarantee a long service life of the filter media of at least 3 to 5 years of operation of the filtering equipment. The filter is equipped with an intelligent regeneration control unit which saves the cost of pressurized air.

 

Multiple types of filtration equipment can be used for welding room exhaust: cartridge filters, fabric filters and slat filters.

 

It is always a great pleasure for us that the client chooses the technology both in terms of acquisition costs and especially in terms of operating costs. Our fabric filters have long filter media life in welding shop exhaust applications. Compared to cartridge filters, the lifetime is about 5 to 10 times longer. Compared to blade filters, our fabric filters have a lower operating pressure drop, which has a positive effect on the total power consumption for the fan used.

 

Our G&G Jet BAG filter equipment for welding shop exhaust applications. The filtering device is equipped with flat textile hoses and regenerated automatically by pressurized air. The design of the filter is such that the extracted air passes downwards through the filter housing. The designed flow helps to convey the separated dust towards the fill and reduces the pressure loss of the filter media. Regeneration of the filter media is controlled by an intelligent control unit that triggers regeneration only when the pressure loss increases. At low pressure losses, the filtration equipment does not regenerate and thus saves the cost of pressurised air. As the pressure loss increases, the intensity of regeneration by means of pressure air pulses also increases. Our partner company was the general contractor for the contract.

 

Filtration equipment for welding plant exhaust

The G&G Jet BAG filtration system for the welding shop exhaust application is advantageous for the operator due to its low filter media replacement costs and the long service life of the filter hoses. Flat non-woven filter hoses with a minimum weight of 500 g/m2 are used as filter media. As a manufacturer, we guarantee a long service life of the filter media, at least 22,000 operating hours, for the welding shop exhaust application. In the case of extraction in the automotive industry when welding grease plates, it is necessary to include a sorbent dosing station prior to the filter classification. The sorbent dosing station ensures the dosing of the CaOH2 sorbent into the suction line upstream of the filter. This system dries the grease from the dust and increases the regenerative capacity of the filter.
