KT-928 Trolley-Mounted Ventilation Duct Cleaning Flexible Shaft Machine:

During long-term operation of central air conditioning ducts and industrial ventilation pipes, dust, particulates, and other deposits accumulate on the inner walls. For short-distance ducts, conventional flexible shaft cleaning equipment may be sufficient. However, when ducts are long and access points are limited, cleaning efficiency is often constrained by shaft length and equipment mobility.

To address these challenges, Anhui Kuaitong Pipeline Cleaning Technology Co., Ltd. has developed the KT-928 Trolley-Mounted Ventilation Duct Cleaning Flexible Shaft Machine.

The KT-928 features a trolley-mounted design and is available with 22 m or 45 m flexible shafts. It supports duct cleaning from 80–800 mm and integrates 0–1000 rpm speed control, forward/reverse rotation, automatic forward/reverse cycling, and manual/remote operation—making it particularly suitable for professional duct cleaning technicians performing long-distance mechanical cleaning.

1. Which Customers Is the KT-928 Primarily For?

The KT-928 is not designed for small, single-duct applications but is better suited for the following customer groups:

Professional Central Air Conditioning Cleaning Companies
Frequently undertaking duct cleaning projects in shopping malls, office buildings, hotels, and other large buildings where duct runs are long and access points are widely spaced.

Large Building Property and Maintenance Teams
Requiring periodic maintenance of central air conditioning ventilation systems, with a need to reduce equipment relocation and additional access openings.

Industrial Facilities
Facilities such as flour mills and chemical plants requiring cleaning of industrial ventilation ducts, dust extraction piping, or material conveying lines.

Pipeline Cleaning Contractors
Requiring professional equipment capable of covering long distances while facilitating site mobility and shaft management.

2. What Problems Does the KT-928 Address?

Insufficient shaft length for long ducts
Standard shafts are limited in length. When encountering long duct runs, equipment must be frequently repositioned. The KT-928 offers 22 m and 45 m shaft configurations—the 45 m shaft extends cleaning reach significantly.

Difficult shaft management
Longer shafts are more prone to tangling, loose coiling, and storage issues on site. The KT-928 features a coil-type holder that allows the shaft to be wound directly on the equipment and released as needed during operation.

Cumbersome long-distance cleaning operations
The equipment supports automatic forward/reverse cycling, reducing manual switching of rotation direction.

Different duct diameters require different brushes
The KT-928 covers 80–800 mm duct diameters, with brush heads available in corresponding sizes.

3. How Does the KT-928 Work?

The KT-928 uses a power drive unit to rotate a flexible shaft.

During operation, a cleaning brush matching the duct diameter is attached to the front of the shaft, which is then gradually fed into the duct. The brush head rotates at high speed inside the duct, mechanically removing dust and deposits from the duct walls.

For dust-type contamination, the equipment can be paired with industrial negative-pressure vacuum systems to collect loosened dust. This combination of mechanical brushing + negative-pressure dust collection is better suited for professional duct cleaning projects.

4. Core Configuration of the KT-928

45 m Long-Distance Shaft
The KT-928 can be configured with a maximum 45 m shaft. For large commercial buildings and industrial ducts, this reduces the need for frequent equipment repositioning due to insufficient cleaning reach.

80–800 mm Diameter Range
Covers a wide range of duct sizes—from smaller ducts to large ventilation pipes. In practice, appropriate cleaning brushes should be selected based on actual duct dimensions.

0–1000 rpm Speed Control
Allows speed adjustment based on dust accumulation and brush specifications. Compared with fixed-speed equipment, this provides more flexible parameter adjustment for different projects.

Automatic Forward/Reverse Cycling
Supports forward rotation, reverse rotation, and automatic forward/reverse cycling. The automatic mode reduces the need for frequent manual operation, particularly beneficial for long-distance continuous cleaning.

Manual + Remote Control
Operators can choose between manual and remote operation based on site conditions.

Trolley-Mounted Structure
The equipment weighs approximately 43 kg and features a trolley design, facilitating site-to-site relocation on large projects.

6. How to Select the KT-928 Based on Project Requirements?

The KT-928 is well-suited for projects with the following characteristics:

① Long duct runs
Standard short shafts cannot reach; multiple access point changes must be minimized.

② Varying duct diameters
The project includes ducts of different sizes within the 80–800 mm range, requiring brush head changes to match diameters.

③ Frequent equipment relocation on site
The trolley-mounted design reduces transport difficulty on long-distance projects.

④ Need to reduce manual operation
Automatic forward/reverse cycling and remote control reduce operational frequency during cleaning.

⑤ High frequency of professional cleaning projects
For professional cleaning companies, large property maintenance teams, and industrial users, long shafts and wide diameter coverage improve equipment utilization.

7. KT-928 Application Scenarios

Central Air Conditioning Duct Cleaning
Suitable for mechanical cleaning of central air conditioning ducts in shopping malls, hotels, office buildings, and other large buildings.

Industrial Ventilation Duct Cleaning
Can be used for cleaning dust and deposits from ventilation ducts in industrial facilities.

Flour Mill Pipes
For pipes with significant dust and powder material accumulation, mechanical brushing combined with negative-pressure vacuum collection can be used.

Chemical Material Handling and Ventilation Pipes
Appropriate brush heads should be selected based on specific media and pipe material.

Important Note: For industrial pipes containing hazardous chemical media, combustible dust, or other special materials, appropriate cleaning methods should be selected only after media verification, risk assessment, and safety isolation are completed.

9. Frequently Asked Questions (FAQ)

Q: What is the biggest difference between the KT-928 and standard duct cleaning machines?
A: The biggest difference is long-distance cleaning capability. The KT-928 can be configured with up to a 45 m shaft and features a coil-type storage structure, making it better suited for large duct and industrial pipeline projects.

Q: Can the KT-928 clean a 45 m duct?
A: The 45 m refers to the shaft length. Actual effective cleaning distance depends on duct configuration, bends, branches, and brush head conditions. Therefore, it cannot be assumed that the KT-928 can continuously clean 45 m in all scenarios.

Q: What duct diameter can the KT-928 clean?
A: The product documentation specifies a cleaning diameter range of 80–800 mm.

Q: Can the KT-928 be operated remotely?
A: Yes. The equipment supports both manual and remote operation.

Q: Does the KT-928 have automatic forward/reverse cycling?
A: Yes. The equipment supports forward rotation, reverse rotation, and automatic forward/reverse cycling.
