Carrier DAMPSLB08X18 Slip-in Bottom Mount Damper 8x18

Product Description

The CARRIER DAMPSLB08X18 is a slip-in bottom mount damper designed for zone control in forced-air HVAC systems. Rated at 24 volts AC with a 15-second travel time, this damper regulates airflow through duct branches to balance comfort across multiple zones. It measures 8 inches high by 18 inches wide and installs directly into compatible ductwork without additional framing. Licensed HVAC technicians install this type of damper as part of a zoning panel system, where individual zones are opened or closed based on thermostat demand. The slip-in mounting style simplifies installation in retrofit and new-construction duct runs alike.

This damper is suited for residential and light commercial forced-air zoning applications. It fits into rectangular duct sections and is controlled by a low-voltage zoning panel operating at 24 VAC. The 15-second travel time provides smooth, gradual airflow transitions that reduce pressure spikes in the duct system. Typical installations include multi-zone residential systems where individual rooms or floors require independent temperature control.

Key Features

• Slip-in bottom mount design for straightforward duct installation without additional framing hardware
• 24 VAC low-voltage control compatible with standard zoning panels
• 15-second travel time for gradual, pressure-friendly airflow transitions
• Sized at 8 inches high by 18 inches wide to fit common rectangular duct openings
• Suitable for both retrofit and new-construction zoning projects

Compatibility

Designed as an OEM-style replacement for use with Carrier and Bryant low-voltage zoning systems requiring a slip-in bottom mount rectangular damper.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Disconnect power to the zoning panel and air handler before beginning work. Slide the damper into the duct opening from the bottom mount position and secure according to the panel manufacturer wiring diagram. Follow all applicable mechanical and electrical codes, including local HVAC and duct construction standards.
