Product Description

Duct cleaning procedure Work includes cleaning entire lineal length of ductwork including drops and rises, cleaning any internal components associated with the ducts (such as fire dampers, sound attenuators, turning vanes, volume dampers) removing and cleaning/disinfecting all grilles and registers (vent covers), replace all vents in the same way they were removed, and clean up after ourselves. It has been our experience that most duct system have little or no access and our procedure includes installing access panels or access doors to gain access. Inspection before Cleaning:- Inspection of Air Duct is an important part of the service. Robocam helps to reach out places where human eye cannot reach. A thorough inspection is done using Robocam and Inspection Video System (IVS). Robocam is inserted into the Air Duct through any of the grills or any opening. Information received on the IVS is carefully viewed and also recorded onto a VHS tape. After viewing the data available, proper measures for taking up cleaning procedure are planned. Duct Cleaning using Negative Pressure Machine and Brush:- After proper inspection and planning, Negative Pressure Machine (NPM) is installed at one end of the air duct and from the other end rotating brush is inserted into the duct. Rotating brush helps in loosening of the dust. Dust is then sucked by the NPM.Duct Cleaning using Air Whip:- The technique is only used if solid dust or debris is stuck onto the walls of Air Duct. Air Whip uses a vibrating and high-pressure air that breaks solid dust particles which gets stuck to walls of air duct. High Air pressure helps in pushing them forward and is then sucked by NPM. Contact Vacuuming:- Lastly contact vacuuming is done. It can reach places where brush cannot reach and also at air duct joints where dust are stuck giving a completely Clean Air Duct. Also grills and filters are cleaned used contact vacuuming. Dust/Debris Disposal:- Dust/Debris disposal is done in very careful manner. Removal of dust from NPM and other machines is done in appropriate way. Dust/Debris is untouched by any workers. It is either disposed of or given to client for chemical test Inspection after Cleaning:- Inspection after cleaning using Robocam and IVS is done to verify whether any dust/debris is left over and has not been removed. It also provides proof of cleaning.
