For collection of non-explosive, fine, potentially hazardous dusts - such as dust arising from ceramic fibres, dusts from asbestos containing materials etc - Type-H vacuums are commonly required (and often mandated by H&S regulations).

Type-H vacuum cleaners are constructed to BS5415 and incorporate multi-stage filtration to deliver filtration standards in excess of 99.995% capture of dust particles as small at 0.3 micron. The final filtration stage incorporates a HEPA (High Efficiency Particle Attenuation) module and each individual filter system is tested and certified for its filtration efficiency. Dependant on intended application the filtration system will be re-tested at intervals as short as 6 months, and in any event at intervals not exceeding 14 months. The HZC 390 Vacuum is ideal for contractors who need a Type-H vacuum only occasionally.

It features a sealed-for-life 13-litre waste container, preventing access to the collected contents, and a HEPA filter
