Self Supported Rigid Box Frame
Extended surface self-supported rigid box filter
AIRFLOW PAK extended surface self-supported rigid box filters are designed for use in air filtration systems and equipment where medium to high efficiency filtration is required. Available in a wide variety of standard sizes and depths, the AIRFLOW PAK provides optimal performance in variable air volume systems.
Galvanized frame construction, diagonal metal support stabilizers, injection molded plastic media separators and expanded metal media support create one of the most rigid filters of its type in the industry.
The media pack, comprised of 100% polypropylene fibers, is bonded to the inside perimeter of the enclosure frame by a moisture resistant adhesive, providing a continuous and positive seal.
The standard offering is rated by Underwriters Laboratories as Class II, per UL Standard 900.
The AIRFLOW PAK is designed so as to work suitably within built up filter banks and/or side access systems. The standard offering is box-type in construction. Peripheral headers, (7/8″) are available as an option.
Rigid construction, extended surface, low initial pressure drop measured in inches w.g., long service life and savings in energy costs are features and benefits which make the AIRFLOW PAK an excellent option for meeting the requirements of medium to high efficiency filtration.
The Airflow Pak is made from 100% synthetic polypropylene microfiber media attached to a 26 gauge galvanized steel frame using a solid, water-resistant adhesive. The media support stabilizers are sturdy polypropylene polymer. Galvanized cross braces upstream and downstream are standard. Sturdy expanded metal faceguards are offered as an option. The Airflow Pak is also available with header.
