Duct and Fitting Cleaning

Clean-Air has developed a variety of techniques and equipment to clean the Duct and Fittings throughout your HVAC System.

Contact Vacuuming

By using HEPA filtered vacuum cleaners the entire surface of each duct is cleaned. HEPA stands for High Efficiency Particulate Air. To be considered as HEPA an air filter must remove 99.97% of all particles greater than 0.3 micrometre from the air that passes through it. This stops any recontamination of the duct by the air which has passed through the vacuum cleaner.

Air Cleaning Brushes

These are air driven devices which make physical contact with the surfaces of the duct to loosen any build-up of dust or debris. They rely on the rotary action and the contact of the bristle to dislodge any debris.

Air Whips

Air Whips are air driven devices which make physical contact with the surfaces of the duct to loosen any build-up of dust or debris. They rely on the whipping action of the tubing to dislodge any debris

Air Bullets

Air Bullets are air driven devices which travel down the duct air sweeping any loose dust or debris. They can be used to move debris forward or backward from the operator to control

Air Compressors

The air brushes and bullets require an air compressor to power them. We use various types depending on the location and access available including our own design of portable air compressors which are extremely easy to manoeuvre through lifts and other tight spaces.

Negative Air Pressure Device

In conjunction with the above equipment we use a Negative Air Pressure Device to apply a negative pressure to the duct to ensure that any loose material is collected. This unit is also HEPA filtered to stop any cross contamination. The insulation and protective surfaces within the ducts can become damaged over time. Clean-Air will repair or replace these items to restore the system. See Insulation Repair and Replacement

Ducts and Fittings can also be treated for Microbiological contamination. See Anti-Microbial Coatings
