Filtration Foams PPI for Air and Liquid Filtration

Filtration foams, also known as PPI foams (pores per inch), are materials with controlled pores used in various filtration processes. Depending on the application, a specific number of pores is selected. These foams are available in two main bases:

• Ester-based (black color): Ideal for smoke filtration, ventilation, and dust.
• Ether-based (blue color): Better suited for liquid filtration, such as aquariums or aqueous systems.

Types of Filtration Foams Available

At Obiform, we offer a wide range of filtration foams to suit different needs. The most common types of PPI foam we provide are:

• PPI 10: Low-density foam, ideal for coarse filtration.
• PPI 20: Recommended for ventilation applications and air conditioning filters.
• PPI 30: A good option for air filters and dust filtration.
• PPI 45: Medium filtration, used in a variety of industrial processes.
• PPI 60: Suitable for finer filtration, such as compressed air systems.
• PPI 80: Ultra-fine filtration, ideal for applications requiring high precision.

We offer these foams in sheets of 2000 x 1000 mm, with the necessary thickness or in pre-cut pieces to size.

Applications of Filtration Foams

Polyurethane filtration foams have multiple applications in sectors such as:

• Ventilation systems and air conditioning.
• Filtration in aquariums and other aqueous solutions.
• Air filters in industrial machinery and devices.
• Control of dust and smoke in industrial environments.

Advantages of Using PPI Filtration Foams

Our air filter foams offer several advantages, such as:

• High durability and resistance to chemicals.
• Flexibility to adapt to various shapes and sizes.
• Efficient filtration in both dry and wet applications.
• Available in a wide range of densities, making them suitable for different sectors.
