Profile of the HemiPleat

State-of-the-art pleating technology is the key to the HemiPleat's superior performance. Synthetic beads hold the pleats of the cartridge open with wide pleat spacing not found in competitive cartridges, which are packed too tightly to maximize media use.

The wider spacing of the HemiPleat design exposes more media to the gas stream and results in lower pressure drop as well as improved cartridge release characteristics during pulse cleaning.

Meeting airflow requirements with a 25% smaller housing allows the Farr Gold Series to deliver premium performance at a competitive price and take up less factory floor space. The service benefits are numerous offering faster, trouble-free change-out of cartridges.

The HemiPleat solved my cartridge life problems. The dust blows right out of the pleats whereas it wouldn't with standard pleats.
