Io Hvac Controls OAD-14-120V Fresh Air Intake Damper 14in 120V

Product Description

The IO HVAC CONTROLS OAD-14-120V is a round fresh air intake damper designed to control outdoor airflow entering a forced-air HVAC system. Operating on 120 volts, it opens and closes to regulate ventilation, helping maintain indoor air quality while preventing uncontrolled outside air infiltration when the system is off. The damper measures 14 inches in diameter and is sized for round duct applications common in residential and light commercial installations. Licensed HVAC technicians typically install this component as part of a fresh air ventilation strategy or makeup air system.

This damper is suited for residential and light commercial forced-air systems where controlled fresh air intake is required. It fits into 14-inch round duct openings and connects to a 120-volt control circuit. Typical applications include whole-home ventilation setups, energy recovery ventilator bypass connections, and makeup air configurations for tight building envelopes. The unit's housing measures 16 inches wide by 16 inches deep by 9 inches tall, allowing installation in standard plenum or duct chase locations where clearance permits.

Key Features

• 14-inch round duct opening fits standard residential and light commercial duct diameters
• 120-volt actuator integrates with common HVAC control circuits and ventilation controllers
• Motorized operation opens and closes the damper blade automatically on demand
• Housing dimensions of 16 x 16 x 9 inches accommodate typical plenum and inline duct installations
• Designed to block unconditioned air infiltration when the system or ventilation cycle is inactive

Compatibility

Designed as an OEM-style replacement or new-installation damper for 14-inch round fresh air intake duct applications in forced-air HVAC systems requiring 120-volt actuator control.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the HVAC system and control circuit before beginning work. Confirm the duct connection is sealed with approved foil tape or mechanical fasteners per local mechanical code requirements. Verify the 120-volt supply circuit is correctly sized and protected before energizing the actuator.
