IRR™(Internal Retention Ring)-N series

IRR™ system utilizes a strong, yet light weight specialty material to construct the internal support ring. It helps the soft fabric air dispersion system retain inflated look without static pressure. The system is extremely light weight, and adds very little extra installation time. The patent pending sew-in pocket construction makes the system very flexible and easy to wash. Additional tension cables at the end of each straight section ensure fabric between rings is kept round and taut when deflated.

ADVANTAGE
Provide full 360 degree support Provide full 360 degree support

Entire portion of the flexible fabric surface remain round and taut when deflated. Fully maintain the inflated appearance.

Keep the full round shape when not inflated Keep the full round shape when not inflated

No inflation / deflation motion, Completely eliminate start up pop.

IRR system is factory pre-installed IRR system is factory pre-installed

It adds very little extra time to system installation. The rings can also be very easily removed for laundering the fabric portion

Light weight and quick installation Light weight and quick installation

The system is also much lighter and easier to transport and install comparing to old generation of external circular or axial metal support system.

Other metal supporting duct system
Half round metal support system. Half round metal support system.

There is still drop or sag at lower part of the duct, wrinkles exist on surface, bad visual appearance.

Multiple points internal support system Multiple points internal support system

Triple points internal support, there is still sag or drop between suspension points, cause interference to the internal airflow. Start-up pop noise can't be erased completely.

Other external metal frame structure Other external metal frame structure

Difficult for packing and transportation,heavy weight, Difficult for installation, it takes 3 times more time to install than Durkeesox IRR system.

WHERE TO USE?
High Demand for Visual Appearance
High Demand for Visual Appearance

Public facilities, offices, sports facilities, and any building that has high demand of aesthetic.
Buildings that require minimum noise. (Including start up pop noise and airflow noise).

Frequently cycled fan / VAV System
Frequently cycled fan / VAV System

Application with prolonged period when the fan cycles on and off during occupied hours.
Large percentage variation VAV system requires the fabric air dispersion system to keep the round shape at minimum occupancy.

Complex Layout
Complex Layout

System with complex layout, excessive fittings and elevation changes can benefit from the easy installation of single row suspension in IRR system
