Abstract Commercially available bag air filters can in principle be regenerated with pneumatic pulses. However, in practice, the loose non-woven filter materials are often damaged, which makes their re-use impossible. This report describes work undertaken with selected needle-punched non-wovens characterized by high air permeability together with good stability during pneumatic pulse regeneration. The behaviour of the filter materials was characterized by pressure loss, reduced service life and loss of integrity of the bag air filter. It was concluded that polyester needle-punched non-wovens with high air permeability were suitable for use in bag air filters with gradual pneumatic pulse regeneration.
