Duct Cleaning

Duct Cleaning

McMahon Services has developed

a proven, patented and unique

solution to clean asbestos

contamination from ductwork

Duct Cleaning

Background

A hidden risk within hundreds of buildings in Australia is asbestos and biological

hazards/dust contamination originating from air conditioning systems.

During the 1960’s and 70’s many buildings were sprayed with asbestos to insulate

the structural steel from deformation during a fire, and the spray was at times

inadvertently directed into air conditioning ductwork. In addition, heater coils within

the ductwork were often insulated with friable asbestos board.

The Solution

The McMahon Services duct cleaning system has successfully completed more

than 100 major asbestos duct cleaning projects across Australia.

The patented cleaning system uses a purpose designed and constructed Ceiling

Access Unit and a unique Cleaning System.

Key Benefits

f The mobile self-contained work area enables cleaning to be undertaken safely,

without the need to establish large enclosures, which are disruptive to tenants

f The patented process ensures superior surface cleaning with no re-working of

areas and eliminates the need to introduce harmful chemicals into the duct to

seal surface residue

f The process enables up to 20 metres to be cleaned in one set-up, via a

single access panel, therefore maintaining the strength and integrity of the air

conditioning system

f Our remote controlled camera inspection equipment facilitates fast, efficient

and thorough inspection with accompanying video record to demonstrate all

asbestos has been removed

CapabilityPlant and Equipment

Ceiling Access Unit

A mobile work unit comprising a

ceiling access work chamber and

decontamination chamber, without

requiring the construction of large

protective enclosures.

The unit ensures the operator is in a safe

environment and not subject to high

pressure air and asbestos fibres.

Cleaning System

A powerful radial blower unit couples

to two pre-filters and a final HEPA filter

ensure that the duct remains under

negative pressure throughout the

cleaning process.

Advanced Video Inspection System

The McMahon Services video inspection

equipment includes the R.I.C.O EHS.

Unlike other remote inspection cameras,

the EHS model is the first camera to

use digital transmission technology that

permits the camera to be accurately

steered within an air conditioning duct.
