Our Products || Drum Filters
The IN-EKO Pile Cloth Drum Filter is a fully submerged, high-efficiency filtration system that delivers reliable removal of fine solids and organic contaminants under even the most variable conditions. Using advanced pile cloth media and continuous OUT-IN filtration, it ensures consistent performance, low operating costs, and uninterrupted operation - making it ideal for municipal, industrial, and aquaculture applications requiring compact, high-quality filtration.
The Pile Cloth Drum Filter uses an advanced OUT-IN filtration principle combined with a fully submerged drum design and specialised pile cloth media.
Unlike conventional drum filters (typically ~65% submerged), this system operates 100% submerged, delivering more stable filtration and higher efficiency. The engineered pile fabric captures fine solids and organic matter while maintaining consistent performance under fluctuating flow rates and high loads.
Continuous filtration during backwashing ensures uninterrupted operation and reliable output quality.
