SMH's range of air filtration units also known as air scrubbers or negative pressure units (NPUs) provides mobile filtered air extraction to control environments where airborne contaminants are a potential risk to human health, such as in pharmaceutical, biomedical, demolition and …

The AM-AIR/5000H is a Negative Pressure Unit (NPU) with a nominal airflow capacity of 5000 m3/h. A machine designed to work in large industrial confinements. It incorporates a speed regulator to adjust the air flow and a pressure gauge to control the status of the filters.

What is a Negative Pressure Unit (NPU)? A negative pressure unit is designed to reduce the risk of stagnant air within an environment: reducing the risk of airborne particulates by creating an airflow system for the air to be extracted. Thermac's NPUs are fitted with HEPA filters to filter harmful airborne particulates while in use.

SMHs dust and air filtration Negative Pressure Units (NPUs) are designed to tackle a wide range of contaminants. The NPU 5000+ has a totally redesigned body. Weldfree, it is easy to clean and the polyethylene case is light and yet still sturdy enough to withstand daily use on site.

The NPU 5000+ is a medium unit in our range, providing a nominal airflow of 5000 m3/hr. It is housed in a weld-free, polyethylene case, making it light and yet still sturdy enough to withstand daily use on site.

RONDA® NPU 5000 is a heavy-duty negative pressure unit for large areas. With 5000 m3/h the machine moves a lot of air and helps to ensure a good working environment at larger demolition-, asbestos removal-, and renovation jobs. The machine is equipped with a large pre-filter, which captures most airborne dust particles.

RONDA NPU 5000 is an effective and user-firendly Negative Pressure Unit for large spaces. By means of its strong suction power, the NPU is able to build up negative pressure inside a defined area. Thereby, the amount of air borne dust particles is reduced, and at the same time the spreading of dust in other parts of the building is prevented.
