Nilfisk CTT40

Industrial Vacuum Cleaners - CTT40CTT 40L

For maximum airflow in explosion-proof environments

Thanks to its small size and high performance, this three phase model is ideal when a powerful machine is needed for confined areas. Functional, compact, stable, solid and easy to operate.

The three phase CTT40 machines have a 4 kW turbine. The suction units are placed on the bottom of the painted steel mobile chassis making the vacuum very stable.
The power is supplied by a 9 metre-long cable with plug. A manometer is installed as standard on the cover in order to check the filter condition. A Class “L” star-shaped polyester filter is fitted as standard, its 19,500 cm² filtering surface ensures highly effective filtration. Furthermore, the external manual filter shaker enables an easy filter cleaning.
Absolute filtration is available by the upstream HEPA 14 filter and the downstream Hepa & Ulpa 15 filters. “L” – “M” & “H” versions are available to meet the EN 60335-2-69 – All.AA and ATEX versions are available as well for all the Zones: 1 – 2 for Gas & Zones 21 – 22.

The steel waste bin with a capacity of 50 litres is fitted with Castor’s and is easily removable by a simple and functional release system. The handle remains on the bin itself for a practical transport.
A wide range of kits/accessories are available to meet the needs of every application.
