Rösler offers a broad range of dust collector systems. The program includes cartridge filters, explosion protected cartridge filters and wet dust collectors. The residual clean air dust load of <1mg/Nm³ achieved with Rösler cartridge dust collectors is well below the legal limits of 3 – 5 mg/Nm³ in Germany. For this reason, additional fine or post (police) filters are not required. Because of the low residual dust load the clean air from the dust collector can be returned into the building without any restrictions. The capacity in terms of air volume extends from 1,000 to 25,000 m³/h (590 – 14,600 cfm). The filter cartridges are easily accessible and can be quickly replaced. The differential pressure switch allows cleaning of the cartridges by a compressed air burst at regular intervals, which considerably extends the cartridge life.
For foundry applications Rösler offers special sand resistant cartridges. A special coating makes them less susceptible to wear from the fine sand in the dust-loaded air. The coating also reduces the adhesion of the bonding agents from the casting mold.
