Io Hvac Controls BN-06-SD Auxiliary Vav Diffuser

Product Description

The IO HVAC CONTROLS BN-06-SD is a 2-foot by 2-foot auxiliary variable air volume (VAV) diffuser with a 6-inch neck, designed for ceiling-mounted supply air distribution in commercial HVAC systems. This unit integrates BACnet communication, allowing it to operate within building automation systems for zone-level airflow control. At 7.25 pounds, the BN-06-SD is sized for standard 2x2 ceiling grid installations. HVAC technicians and mechanical contractors install this diffuser where digitally controlled zoning is required, particularly in light commercial and office environments where VAV systems manage occupant comfort and energy efficiency.

The BN-06-SD is suited for commercial VAV air distribution applications in 2-foot by 2-foot suspended ceiling grid systems. Its BACnet protocol support makes it compatible with open-architecture building automation systems, enabling integration with third-party controllers and building management platforms. Typical install scenarios include multi-zone office buildouts, tenant improvement projects, and commercial renovations where zone-by-zone airflow control is specified. The 6-inch neck connects to standard round duct branch takeoffs commonly used in low-pressure VAV distribution systems.

Key Features

• BACnet communication protocol for open-architecture building automation integration
• 2-foot by 2-foot face fits standard suspended ceiling grid openings
• 6-inch neck diameter connects to standard round duct branch takeoffs
• Auxiliary VAV design provides zone-level airflow modulation
• Compact profile at 12.5 inches height for above-ceiling plenum installations

Compatibility

Designed as an OEM-style replacement or new-installation VAV diffuser for commercial ceiling grid systems using BACnet-compatible building automation controllers.

Installation Notes

Installation should be performed by a licensed HVAC technician or mechanical contractor familiar with VAV system commissioning and BACnet device configuration. Power down the VAV system and de-energize the control circuit before making electrical connections. Verify that the existing ductwork branch takeoff matches the 6-inch neck diameter before mounting. BACnet device addressing and network integration should be completed and tested per the building automation system manufacturer's commissioning procedures.
