Description
The Filtrair TP series pocket filters are designed for optimal performance and longevity. Their rigid design prevents particle migration in Variable Air Volume (VAV) systems and ensures stability even when airflow is reduced. The filters use synthetic fiber-based media developed in the Netherlands, featuring a multi-layer construction for high dust holding capacity and low pressure drop.

Flammability Ratings
The filters meet German fire classification standards (DIN 53438-F1).

Features and Benefits

• Rigid thermal pocket design suitable for VAV systems and turbulent air streams.
• Aerodynamic pocket separators for uniform airflow and maximum media usage.
• Low resistance reduces operating costs significantly.
• High dirt holding capacity, 2-3 times more than traditional filters.
• Efficiency levels include 35%, 45%, 55%, and 65%.

Applications
These filters are ideal for general ventilation and air conditioning in hospitals, universities, research and manufacturing facilities, commercial buildings, and industrial plants. They are also suitable for supply air units in surface finishing applications like automotive painting.
