Compared to needle felt filter bags, ultra long-life filter bags use finer and heavier fiber. In situations where there are little change in differential pressure, it increases medium porosity and filtration area thereby increasing dirt-holding capacity and filtration efficiency. Its service lifespan is also 2 – 5 times that of traditional bags. This lengthens production cycles and reduces the need for changing bags thereby reducing operating costs.

Long life filter bag can be applied in situations where filtering flow rate is big and filtration accuracy requirement is high.

Product features:

Tight structure without surface felt shedding;

Hot-melting seamless joint technology ensures no side leakage or chemicals exudation;

Suitable for fluid with low or medium viscosity to effectively intercept various solids and soft particles under high flow rate;

Fully welding for joint, special surface heat treatment and reduction of surface fiber shedding in service;

Fineness and thickness of fiber increase the porosity factor of filtering layer and range of particles being intercepted to increase the pollutants holding capacity and service life;

Reducing filter-bag loss, machine down time, bag replacing time and storage and discarding cost to finally cut overall cost;

No.1 or 2 bag is selectable according to customer’s actual operating environment;

Plastic pressure-sensitive sealing ring with good sealing performance or economical but durable stainless steel or carbon steel ring is selectable according to customer’s actual operating environment;

Non-standard design is available according to customer’s actual operating environment.
