Welding Filters

Gram Clean Air cyclone filters offer state-of-the-art industrial air filtration technology, ensuring efficient dust extraction and particle separation in demanding production environments. Our extensive product range includes compressed-air-cleaned filter systems with air volumes from 500 m³/h to 45,000 m³/h, providing scalable solutions for businesses of all sizes.

Using centrifugal force, our cyclone separators create efficient pre-separation that reduces the load on the filter material, extends the filter service life, and lowers operating costs. The two-stage solution combines cyclonic dust collection with vertical filter cartridges, ensuring optimal particle removal – from fine welding fumes to coarse grinding dust.

Our product range comprises four series: ACF (high-capacity units up to 40,000 m³/h), CJF (compact filters for confined spaces), FL Filterline (integrated Plug & Play systems with fans), and QFG (maximum-capacity solutions up to 45,000 m³/h). All units feature energy-efficient design, a cleaning system controlled by pressure differential, and easy installation, as they are delivered fully assembled.

W3-certified versions meet the most stringent filtration requirements, while low compressed-air consumption and minimal maintenance needs ensure maximum performance at minimal cost. Our cyclone filters are ideally suited for metalworking, welding, grinding, and powder handling, ensuring workplace air safety while optimizing operational efficiency.
