What Filter Housings are Suitable for Chemical Solvent Filtration?

Chemical solvent is a substance that can dissolve solids, liquids, gases, common types of solvents are aromatic hydrocarbons, aliphatic hydrocarbons, alicyclic hydrocarbons, halogenated hydrocarbons, alcohols, ethers, esters, ketones, glycol derivatives, etc., and inorganic solvents are generally acidic solvents, alkaline solvents, amphoteric solvents, inert solvents and so on. Different components of chemical solvents will choose the corresponding material filter, usually choose PPH filter housing, PVDF filter housing and FRP filter housing.

PPH (Polypropylene Homopolymer) Filter Housing

1. What are the types of PPH filter housing?

Ⅰ. PPH Bag Filter Housing

PPH Bag Filter Housing can be categorized into swing bolts type and screw cap type according to the structure of the filter housing. Hongtek's PPH bag filters can be adapted to different sizes of bags (e.g., Size #1, Size #2, Size #4, Size #5 and Size#6, etc.) according to the requirements, and there are also multi-bag PPH filter housing to choose from.

Ⅱ. PPH Cartridge Filter Housing

In order to meet the requirements of different project sites, Hongtek has developed a variety of different specifications of cartridge filter housing for selection. It can be adapted to pleated filter, melt blown filter and string wound filter, etc., and can be installed with different lengths of cartridges (e.g., 10 inches, 20 inches, 30 inches, 40 inches, etc.) and there are also multi cartridge model from 1 round to 53 round are available.

Ⅲ. PPH High Flow Filter Housing

Hongtek has also developed PPH high flow filters that are easier to install and replace, reducing filter maintenance costs and system downtime. PPH high flow filter housing can be adapted to 10 inch, 20 inch, 30 inch and 40 inch high flow filter cartridges. In addition, in order to meet the needs of different flow rates, we can also customize the PPH high flow filter housing from 1 round to 7 rounds.

2. What kinds of chemical solvents are PPH filter housing suitable for?

PPH is a thermoplastic resin material polymerized from propylene monomer, which has excellent chemical resistance, heat resistance, pressure resistance and impact resistance, and good stability to most chemicals and solvents. The substances in the table below are some of the common chemical solvents that are compatible with PPH filter housing.

PVDF (Polyvinyl Fluoride) Filter Housing

1. What are the types of PVDF filter housing?

Ⅰ. PVDF Bag Filter Housing

The housing body and cover of Hongtek's PVDF bag filter is fixed and locked through swing bolts, which are suitable for size #2 filter bag. Since PVDF filter housing are usually used to filter highly corrosive chemical solvents, filter bags made of highly corrosion-resistant materials such as PVDF, PTFE and PES are generally selected.

Ⅱ. PVDF Cartridge Filter Housing

Hongtek's PVDF cartridge filter can be adapted to different types of filter elements, such as pleated filter, melt blown filter, string wound filter, etc. Consumables are generally made of PVDF, PTFE, PES and other materials with strong corrosion resistance. Now 40 Inch with 5 round model are available.

2. What type of chemical solvents are PVDF filter housing suitable for?

PVDF is a polymer material made form the polymerization of vinylidene fluoride. It has high mechanical strength, excellent thermal stability, radiation resistance, chemical corrosion resistance and ultraviolet resistance. It is compatible with most chemical solvents. The substances in the table below are some common chemical solvents that are compatible with PVDF filter housing.

FRP (Fibre Reinforced Plastic) Filter Housing

1. What are the types of FRP filter housing?

Ⅰ. FRP Bag Filter Housing

The housing body and cover of FRP filter housing is fixed and locked through SS316 swing bolts. It is usually installed with size #2 filter bag. In order to meet the different flow requirements of various project sites, Hongtek provides FRP bag filter that can be adapted to 1 bag, 3 bags, 4 bags, 5 bags, 6 bags and 7 bags.

Ⅱ. FRP Cartridge Filter Housing

The consumables of FRP cartridge filter housing generally choose pp melt blown filter or pp string wound filter. Hongtek's FRP cartridge filter housing can be adapted to filter elements with length of 20 inch, 30 inch and 40 inch. FRP cartridge filter housing with 5 round, 12 round and 22 round are available now.

Ⅲ. FRP High Flow Filter Housing

In order to reduce filter maintenance costs and shorten system downtime, Hongtek has developed FRP high flow filter housing that are easier to install and replace. It usually installs with 40 inch length high flow filter. In order to meet the flow requirements of more different projects, we also provide FRP high flow filter housing with 1 round, 3 round, 4 round, 5 round, 6 round and 7 round.

2. What types of chemical solvents are FRP filter housing suitable for?

FRP is a high performance fiber composite material mainly made of glass fiber and epoxy resin through wire winding, molding, pultrusion and other molding processes. With its chemical resistance, wear resistance, light weight, and high strength, it is often used in chemical solvent filtration. The substances in the table below are some common chemical solvents that are compatible with FRP filter housing.
