The three brush tools included in the 94311 have a curved surface designed to engage the surface of ventilation duct or other similar round surfaces from 6” in diameter all the way up to five feet in diameter

Cleaning HVAC ducts overhead used to mean wobbly ladders, dropped tools, and a sore neck. The Cen-Tec Systems 94311 changes that with a 12-foot reach system that keeps you safely on the ground while tackling ducts from 6 inches to 5 feet in diameter. The curved brush heads wrap around round ductwork to scrub away dust and debris that standard vacuum attachments can’t touch.

What makes this kit stand out is the secure locking mechanism on every connection point. When you’re working overhead or from a platform, the last thing you need is a brush head crashing down. Each piece locks firmly in place so you can focus on the cleaning job instead of worrying about equipment failure. The system connects directly to your existing vacuum setup whether you’re using a commercial backpack unit, a shop vac with 1.5-inch hose, or professional equipment from brands like ProTeam, Hoover, or Bissell.

Who Is This For?

This kit works for facility managers maintaining commercial HVAC systems, contractors offering duct cleaning services, and homeowners with high ceilings or exposed ductwork in basements and garages. If you’ve got round ventilation ducts that are hard to reach and you already own a compatible vacuum, this extends your cleaning capability without requiring a completely new system. The 12-foot reach handles most residential and light commercial applications without scaffolding.

Bottom Line

The Cen-Tec 94311 solves a specific problem: cleaning overhead round ducts safely and effectively with equipment you likely already own. The curved brushes actually conform to duct surfaces instead of just poking at them, and the locking connections mean you won’t be dodging falling tools. It’s a practical addition to your cleaning arsenal if ductwork maintenance is part of your regular routine, whether professionally or around your own property.
