Pleated filter bag products provide an efficient alternative to conventional bag filters and we provide a range of pleated bags filters for conventional bag collectors and pleated bag collectors.

With a range of more than 20 high-quality filter media, EFS provides air filtration solutions for various industries and dust types, including abrasive, toxic and explosive dust.

We specialise in dust and fumes from cement, metal/aluminium, food & beverages, woodwork, chemicals, powder coating, plasma/laser cutting, sandblasting, textiles, welding and casting.

Here you will find more information about our pleated bag cartridges. However, please contact us directly for enquiries about other cartridge types or customised filter cartridges.

Benefits of Pleated Bags

  • Polyester media and PU end caps in the bottom prevent abrasion/leaks.

  • Can be retrofitted into existing bag filter dust collectors using existing tube sheet holes (adaptor rings enable easy installation in tubesheets ranging from 152 – 167 mm diameter).

  • Short pleated bag filters can optimise the capacity of existing collectors – hence prevent the need to invest in larger baghouses. Also, they require less air for efficient pulse cleaning.
