| Advantages︰ | SNAP-RING Filter Bags
According to the result of research from a famous company, for over 30 years SNAP-RING Filter Bags have been a critical component of filtration systems worldwide. A huge selection from which to choose, affordable cost, and reliable, consistent performance have made them a popular choice for many applications.
SNAP-RING filter Bags are manufactured from the best available materials of America, Canada and Europe. Saar produces these filter bags under euramerican quality control standards¡ensuring that the filter bag you get today will perform exactly the same as the one used last month or last year. There will be no variations in performance to compromise the quality of your filtration process.
A heavy duty sewing process is used by Saar to construct all SNAP-RING Filter Bags. A solid ring, of either plastic or metal, is sewn into the top opening of the filter bag. This ring seals the bag into the filter housing.
Saar follows strict engineering standards in sourcing raw materials and in the manufacturing process of all filter bags to ensure that they are 100% good quality.
Whether you have a filter vessel from Saar or a vessel from another manufacturer, there is a SNAP-RING Filter Bag that will fit it perfectly. So no matter what type of filter vessel your application uses, you can take advantage of the performance benefits afforded by a SNAP-RING Filter Bag from Saar.
Affordable SNAP-RING Filter Bags are available with four different rings materials, fourteen different fabric materials and fourteen different micron ratings. With a choice this wide you can pick the perfect filter bag for your application. You'll never have to pay for more filter bag than you need, or settle for a filter bag that is not quite up to your requirements.

SENTINEL Ring Filter Bag Seal
The Sentinel all-plastic collar is an improvement over other filter bag sealing systems. The Sentinel collar fits into the filter vessel housing in a unique manner that provides a positive, self-energized seal in the filter vessel that restricts the process fluid from bypassing the filter bag. This seal is enhanced as the pressure differential increases during operation.
Saar¡¯s Sentinel collar design also creates a constant, radially-directed pressure to prevent the ring from collapsing into the restrainer basket.
The elevated handles, which remain above the liquid, make bag change out fast and efficient. Contact with aggressive fluids is greatly reduced.
The patented Sentinel ring is your assurance of a bypass-free filtration system. Combined with fully welded media construction, the Sentinel ring assures that every drop of liquid is filtered with no bypass.
The Sentinel ring is available in 4" and 7" diameters.
Design specialty :
1. Handles on Sentinel ring bag remain above fluid level for easy removal.
2. Filter bag with Sentinel ring fits perfectly inside filter vessel.

Saar Welded Construction Filter Bags
Now, applications requiring polypropylene or polyester felt filter bags can take advantage of all welded construction filter bags from Hayward.
In these bags, which feature super strong welded construction, the seams and ring seal of the bag fabric are welded, rather than sewn. This ensures that there can be no bypass of the process media through holes in the fabric created as a result of a sewing process.
Saar uses a unique, patent pending manufacturing process to produce a filter bag with a consistent and durable welded seam. This process also shapes the bag to conform to the internal shape of the filter bag restrainer basket.
Another advantage afforded by this patent pending technology is precision bonded cutting of the fabric edges. Fiber migration can result from loose fiber released by ordinary fabric cutting operations.¡but not with a Welded Construction Filter Bag from Saar. The fabric for every bag is cut by a special technique that ensures smooth and BONDED fabric edges with no loose fibers or strands to contaminate the downstream flow.
Saar follows strict engineering standards in sourcing raw materials and in the manufacturing process of all filter bags to ensure that they are 100% good quality to be meet the euramerican quality control standard.
Finally, every Welded Construction Filter Bag uses Saar¡¯s sentinel ring collar¡which insures a perfect seal between the filter bag and the vessel for no-bypass filtration. If the filter bag is disposed of by incineration, this plastic ring will cause no problem as a metal ring might.
