Strong 4000 Negative Pressure Unit, 2018, Vantaa

Strong 4000 is one of the most powerful negative pressure units on the market. It combines high power, low operating noise and a light yet robust construction. The Strong 4000 introduces a completely new filter solution: in this model a single large HEPA filter is replaced by 16 smaller filters. The solution brings several advantages, such as reduced weight and significantly lower filter costs. This approach keeps the airflow at an unusually high level, and the total HEPA filter area meets requirements for, for example, asbestos work. In the event of a human-caused filter breakage you do not need to replace the whole HEPA module, only the damaged filter cartridge.

The unit has a powerful, automatically adjustable motor that increases torque as back pressure rises.

The Strong 4000 is suitable both for depressurising large spaces and for air cleaning: its task is to capture airborne dust and prevent it spreading to clean areas.

The unit can be fitted with either HEPA H13 cartridge filters or a HEPA H14 box filter.

The total air volume of the Strong 4000 negative pressure unit measured using the comparable Bellmouth measurement method (VTT) is 2600 m³/h. Remember to request Bellmouth measurement documentation for easier comparison.
