Workbook: Dust extraction for Dry Vent

STEP 2 OF 2

Cleaning Process

With equipment properly set up, the cleaning process focuses on efficiently removing dust and debris while monitoring for consistent performance throughout.

a. Power on the device
- Turn on the vacuum or dust extractor before inserting any tools into the vent.
- This creates negative pressure, preventing loosened dust from blowing back into the room.
- Check that air is flowing through the hose — poor airflow at this stage suggests blockages or poor suction.
b. Adjust Settings Based on the Environment
No two vents are alike. Use these environment-based guidelines to avoid over-agitating fragile ducts or under-cleaning robust commercial systems.
- Residential Dry Vent (typically 4" aluminum or semi-rigid flex duct):
  - Use medium suction to avoid collapse or tearing.
  - Start with soft brush heads.
  - Avoid over-extending powered rods that could puncture elbows or joints.
- Commercial Vent Systems (metal ducting, long runs):
  - Use maximum suction and firm brushes.
  - Employ rotary brushes powered by a drill for deep cleaning.
  - If debris is compacted or oily, use compressed air tools to dislodge before vacuuming.
- Adjust Cleaning Tools Based On:
  - Length of vent: Use longer rods or camera extensions.
  - Bends or elbows: Be gentle when navigating to prevent tool jamming.
  - Moisture: Wet lint may require slower passes and more suction to remove.
c. Monitor Airflow and Coverage
No two vents are alike. Use these environment-based guidelines to avoid over-agitating fragile ducts or under-cleaning robust commercial systems.
- Real-Time Monitoring Tips:
  - Check the extraction hose for debris movement — a clear stream of lint confirms effective suction.
  - Use a vent camera or flashlight to check wall buildup before and after cleaning.
  - Visually inspect exterior vent flap or hood for lint discharge and full airflow.
  - After a full pass, run the vacuum a few extra minutes to collect any remaining suspended dust.
- Quality Control:
  - Wipe down vent edges and surrounding walls.
  - Take a before/after photo using inspection camera for record-keeping or customer confidence.
- Log:
  - i. Date and time of service
  - ii. Type of equipment used
  - iii. Amount of debris collected (rough weight or bin capacity)
  - iv. Any issues encountered (e.g., bird nest, crushed duct, clogged lint trap)
