Liquid Bag Filter

Good Life Starts with Clean Liquids: Liquid Bag Filters – Your Pathway to Purity

Bag Filter: Polypropylene / Polyester

Aarvi Energy Filter bags are cheap and powerful filters. They are made from textile needle felts made of polypropylene or polyester in various micron ratings. The top is sealed by a welded plastic collar; the sealing lips ensure a bypass free sealing. The collar material is adapted to the respective filter material to avoid resistance problems. All abutting edges are welded, particle migrations through seams and needle holes are a thing of the past.

Filter Bag- Monofilament: Nylon

Aarvi Energy monofil filter bags are made of textile nylon square mesh in various micron rates. The top is sealed by a welded plastic callor; the sealing lip ensure a bypass free sealing. These filters find their application mainly as a surface filter in the pre-filtration for retention of coarse particles. Also wash and re-use is common practice for these filter bags.

Filter Bag Needle Felt & Monofilament

Aarvi Energy Filter bags PP / NM are cheap filters which are characterized by high efficiency and high performance. They have been developed specifically for use in PBH filter housings. The top is sealed by a welded-sealing adaptor. All joints are also welded at the BP / BN are available in polypropylene and nylon. All processed materials are free from harmful substance, such as silicone.

Pleated Bag Filter Element

High performance Pleated filter elements combine the advantages of conventional filter bags and filter cartridges in one filter element. By the patented pleating a substantially bigger filter surface (3.15 m2 to 0.5 m2) is reached compared with filter bags. Service life and dirt-holding capacity will increase several times. Analogues to the filter bag is the filtration from the inside instead of the outside. All dirt particles are reserved inside the filter element and will not contaminate the clean room during the filter change.

High Temperature Pleated Bag Filter Element

Aarvi Energy High performance filter elements combine the advantages of conventional filter bags and filter cartridges in one filter element. By the patented vertical pleating a substantially bigger filter surface (4.4 m2 to 0.5 m2) is reached compared with filter bags. Service life and dirt-holding capacity will increase several times. Analogues to the filter bag is the filtration from the inside instead of the outside. All dirt particles are reserved inside the filter element and will not contaminate the clean room during the filter change. High temperature fluids, Glycols, Fuels, Process fluids, Various hydrocarbons, Biofuels, Organic solvents, Produced water& Disposal water

Bag Filters Element

Aarvi Energy High performance filter combine the advantages of conventional filter bags and filter cartridges in one filter element. It is produced by the patented melt blown process. In this case the pore structure and the polypropylene fibres are from the inside to the outside increasingly refined. This structure allows the storage of different sized particles of dirt. Thanks to its large filtration thickness they have a particularly high-performance depth filter. Analogues to the filter bag is the filtration from the inside instead of the outside. All dirt particles are reserved inside the filter element and will not contaminate the clean room during the filter change.

Oil Absorbent Bag Filters

Aarvi Energy manufactures two different types of Oil Absorbent Bag Filters and in different sizes. These Absorbent bags are made from multiple layers of polypropylene micro fiber nonwoven that attract (oleophilic) oil droplets within the nonwoven matrix.

The degree of effectiveness of these bags is dependent on the type of oil you are trying to remove as well as the differential pressure across the bag filter media. The greater the differential pressure the greater the propensity will be for the oil droplet to deform, and migrate downstream which you don’t want.

For this reason, we encourage you to use gauges on your housing to decrease your risk of forcing oil droplets downstream.
