Profile HemiPleat

Our innovative pleating technology is the key to the exceptional performance of HemiPleat filters. Synthetic ribs hold the cartridge folds open with a large spacing that is not found in our competitors; their cartridges have indeed too tight folds preventing optimum use of the media.

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 Offering Numerous benefits are faster, trouble-free change-out of cartridges.

The wider spacing of HemiPleat filter pleats can expose a greater portion of the media to the gas flow, which reduces the pressure drop and improves the declogging of the cartridges when cleaning pulse.

With air boxes 25% less bulky to air flow / pressure equal, allows Farr Gold Series units offer the highest level of performance at competitive prices, to save space. The advantages in terms of maintenance are many, thanks to easily and quickly replaceable cartridges.


"HemiPleat solved my life problems cartridges. Unclogging folds is very effective, something you do not see with the folds of the standard cartridges."

What is HemiPleat Synthetic?

Camfil APC HAS brought` together two proven technologies of ict to Produce a dust collector filter with an efficient hybrid media suitable for harsh environments and humid able Maintaining of long life. NEW This media offers all the advantages of HemiPleat technology with the durability of Dura-Pleat® media.

HemiPleat Synthetic is a light-weight 100% spun bond polyester media in a pleated design maximizes That area area while Maintaining open pleat spacing. The 'wider spacing of the HemiPleat design more media exposed to the air stream qui results in lower pressure drop and Improved dust release During pulse cleaning. The light-weight polyester design Promotes an Increase in filtration area area at no added cost When Compared To the Dura-Pleat filter.

HemiPleat Synthetic media is available for Farr Gold Series ®  Gold Cone filters as well as retrofit filters to fit competitor dust collectors.


Sturdy and durable, this media is moisture resistant and is not affected by harsh environments in humid operating temperature of 160 degrees Fahrenheit or less. This washable media May be reused in Many applications.


Key Benefits of Synthetic HemiPleat

  • More media available for filtration resulting and in Improved performance and longer life.
  • Washable media and resistant to moisture.
  • Ideally suited to tough applications Including heavy dust loading requirements and / or hygroscopic dust properties as seen in the food and pharmaceutical industries.

State-of-the-art pleating technology is the key to the HemiPleat's superior performance. Techniques used to manufacture the media packs of this cartridge are single, patented, and never-have-been Applied to a cylindrical industrial dust collection filter before. Synthetic beads hold the pleats of the cartridge open with wide pleat spacing not found in competitor cartridges, qui are packed too tightly to maximize media use.

Synthetic HemiPleat est disponible with  eXtreme nano fibers  Applied. The eXtreme layer acts like a prefilter to the media base and Does not allow dust particles to MOST "depth load" (or embed in the media). Most of the dust is captured at the area of the media Because The pores on the eXtreme media are so small. This "loading area" is what Increases the cleaning filters Ability, qui in turn extends filter life.

HemiPleat ®  compared to competitive filters

The manufacturing technology of the media of our filter cartridges is unique and does not exist in any other industrial dust filter. Synthetic ribs maintain the folds of the cartridge open with a large spacing; in the cartridges of our competitors, the folds are too tight, which prevents air circulation.

The wider spacing of the folds of HemiPleat filters can expose the entire media to the airflow, thereby reducing the pressure drop and improves the declogging of the cartridges when cleaning pulse.
