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 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 0.3 microns, the HEPA (High Efficiency Particulate Air) filter can clean contaminated air of potentially harmful particles such as asbestos, bacteria and some viruses.
