Produkteinführung

Round inlet and outlet transitions distinguish this safe-change housing from rectangular AHU sections. The welded stainless cabinet retains a side-access bagging ring while adapting the filter cell to circular ventilation ductwork. Gasket or gel sealing can be selected to match the HEPA element. Because the transition geometry affects face distribution, the inlet diameter and available straight length must be coordinated with the filter airflow.

Key Features

Circular duct integration

Factory transitions connect a rectangular HEPA face to round process or exhaust ductwork.

Compact containment section

A single side-service cabinet reduces field transition work on small vent lines.

Selectable seal interface

The internal frame can be arranged for a compressed gasket or gel-trough filter.

Applications

For compact nuclear support vents, biocontainment exhaust branches and process ducts that use round connections but require contained HEPA replacement.

Solutions for Your Application

A short round transition creates a high-velocity jet across only part of the HEPA face.Size the transition angle and straight length for uniform distribution and verify filter-face velocity at design flow.

The bagging port collides with nearby circular duct supports.Coordinate door swing, bag extension and hanger positions on the installed layout before fabrication.

Verfügbare Optionen

Confirm duct diameters, airflow, transition lengths, stainless grade, filter seal, access side, test ports and support brackets.
