Cartoli Instruments

Cartoli Instruments supplies 4" duct cleaning brush options and related rotary brush accessories for HVAC and vent maintenance. These 4-inch brushes are commonly used for dryer vent cleaning and for smaller branch runs where a compact diameter improves maneuverability. Rotary brushes for duct cleaning setups may include flexible shafts, extension rods, adapters, and replacement heads designed to navigate bends while maintaining consistent contact with the duct wall. Technicians use these tools to remove lint, dust, and debris that restrict airflow and increase fire risk, then document results with inspection cameras when required. Cartoli offers contractor‑ready kits and replacement parts, with guidance on matching brush diameter, material, and drive compatibility to the specific duct type and service workflow. Options are available for common residential and light commercial applications, including tight chases and longer exhaust runs.
