SMH NPU2500 Negative Pressure Unit

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 demolition and remediation work. They are designed to create negative pressure within a portable decontamination unit facility or working enclosure. All SMH NPUs comply with BS EN 8520-2:2009.

The NPU 2500+ is the latest addition to SMHs range of NPUs, with a totally redesigned body weld-free, it is easy to clean and the polyethylene case is light and yet still sturdy enough to withstand daily use on site.

Its powerful motor provides a huge nominal airflow of 2750m³/hr for what is still a relatively compact size and lightweight. With particle filtration of 99.995% at 0.3µm, the HEPA (High Efficiency Particulate Air) filter can clean contaminated air of potentially harmful particles such as asbestos.
