Contaminated ductwork systems can create an ideal environment for microbiological growth, leading to the spread of bacteria. Filtrex offers cleaning and decontamination of dust and debris from within ventilation systems, and a deep clean of plant using our Filbac antibacterial cleaning solution.

Grease in kitchen extract systems poses a serious fire risk. Filtrex provides a complete cleaning and degreasing service for kitchen extract systems and carry out fire damper inspections.

In LEV systems, dust build up in the ductwork leads to a reduction in air volumes resulting in extraction levels dropping. It can also be a major fire hazard, especially in ATEX classified zones. Filtrex carries out complete LEV system cleaning to ensure your extraction systems are kept working efficiently and safely.

As part of our cleaning and hygiene service, we also use a variety of specialised machinery that can enter into the duct called the DuctAsp, DuctBoss and DuctEye. These systems provide CCTV or photographic surveys of ductwork systems and sample testing to give an accurate report of the condition of your ductwork.

Specialist cleaning equipment allows correct and invasive cleaning of hard to reach and process extraction/supply lines.  Remote video cameras and cleaning equipment will verify long ductwork lengths from one access point.  This avoids the disruption of scaffolding and difficult access arrangements for high level ductwork or ductwork over plant machinery and production equipment.

DuctAsp surveys and cleans the ductwork all at once. It can be inserted into hard to reach air handling or LEV ductwork, which then is jet blasted by compressed air and released into a negative suction chamber to be collected.

The DuctAsp is excellent for verification of LEV systems that are handling food production clear out the duct deposits that harbour microbial build up.

A cleaning certificate with before and after images are supplied following successful completion of the system clean.

DuctBoss offers the perfect drive into the ductwork internals to assess cleanliness and blockages from different viewpoints. The DuctBoss can travel up to 40 meters from one access point to assess the dust build up and can be used to verify ductwork cleaning programmes.

DuctEYE shows you exactly what is going on in the ductwork and LEV aspirations systems.  When dust builds up in ductwork leads it causes a reduction of air flow volumes resulting in extraction levels dropping.  Blocked ducts effect efficiency of the fans as they have to work harder.  The DuctEYE will detect and assist in keeping your ductwork safe and clean.

The Filtrex Rotary Brush can survey and clean economically as only one person is required to handle the entire process.

It is ideal for use in grease systems as a dense foam is discharged into the duct and attaches itself to the wall that then melts off the grease.  Grease build up in kitchen extract poses risk of a serious fire.  Filtrex provides a complete clean and de-greasing service for kitchen extract systems and carry out fire damper inspections.  Video-verification with before and after images can be supplied.
