The high capacity rigid bag filters (Series FTRV) are a successful innovation with respect to the traditional soft bags. The filtering septum made on glass microfibre, water repellent and fireproof, is finely pleated and separate with continuous thermoplastic spacers. so you get a filter pack with small pleats and constant pitch, with constant with good dust accumulation capacity and low pressure drops.
