How to Properly Install Nozzles on a Mosmatic Duct Cleaner

Installing Mosmatic nozzles the wrong way can lead to poor cleaning performance and equipment damage. The correct method is to install them horizontally, not vertically. Here’s how to do it right.

Why Horizontal Installation Matters

Mosmatic duct cleaners are designed to produce a balanced spray pattern that effectively cleans the interior walls of ducts and hoods. To achieve this, nozzles must be installed so they spray out horizontally.

  • Maximizes surface coverage inside the duct
  • Ensures smooth rotation and turbine balance
  • Reduces wear on internal components
  • Improves cleaning consistency and efficiency

What Happens If Nozzles Are Installed Vertically?

Installing the nozzles vertically (facing up and down) may seem like a small mistake—but it can lead to major issues:

  • Unbalanced rotation and vibration
  • Inefficient cleaning pattern
  • Missed surface areas inside the duct
  • Premature wear on bearings and spray arms

Always install the nozzles so they spray side-to-side—not up and down.

Step-by-Step: Installing Nozzles the Right Way

  1. Check the Spray Arms: Locate the threaded ports at the ends of each arm.
  2. Align Horizontally: Hand-thread the nozzles so the spray jets point sideways (not vertically).
  3. Tighten Carefully: Use thread sealant if needed, and secure the nozzles with a wrench.
  4. Run a Test: Test spray the system before use to confirm proper alignment and rotation.
