Product Description

These Lamb Electric carbon motor brushes (part number Star 27-43838) are OEM replacement components designed for Lamb central vacuum power units. Supplied as a 2-pack, these brushes are critical wear items that maintain electrical contact between the rotating armature and stationary field coils, ensuring consistent motor performance and longevity.

Carbon brushes are engineered for reliable current transfer in high-speed motor applications. As brushes wear over time, they naturally reduce in length and should be replaced to prevent motor damage, noise, and efficiency loss. These genuine Lamb brushes meet OEM specifications for fit, electrical conductivity, and durability.

Compatible with Lamb Electric central vacuum motors used in residential and light commercial central vacuum systems throughout the Wasatch Front.

Use Case

Central vacuum motor brushes wear gradually with normal use and should be inspected annually. If your system has lost suction, makes grinding or squealing noises, or sparks are visible inside the power unit, brush wear is likely the cause. Replacing carbon brushes is a cost-effective maintenance procedure that extends motor life by 5+ years and prevents catastrophic motor failure. Homeowners with established central vacuum systems should keep a spare 2-pack on hand for routine maintenance or emergency repairs.
