Type H and H Class (Hazardous or Toxic Material)


When the collected dust is determined to be hazardous special filtration and protection must be incorporated into the industrial vacuum cleaner to meet exacting standards.

 

 

But, what standards? Trying to digest the various classifications and standards for HEPA filters and Industrial Vacuum Cleaners for hazardous and toxic materials can be challenging. Many Filters in BVC Vacuum Cleaners are manufactured by a leading Worldwide filter manufacturer, and when we recently asked them to confirm the current standards they use for the HEPA filters they supply to us, gave us the following answer:-

HEPA FILTERS

“There are essentially 2 types of test that we use for our HEPA filters. The first is BS3928 the Sodium Flame Test. We use this for all our nuclear grade filters as it is specified in the nuclear filter standards and is the test used for all filters supplied to the MOD. The standard is now 50 years old and is likely to be reviewed in the next year or so, however the basic method, test and validation criteria are unlikely to change.

Then there are the DOP tests which are carried out on all our other, non nuclear grade HEPA filters. The standard test specification for these has been BS EN 1822 which was published in 2010. Parts of this have now been superseded by ISO 29463 from 2018. However part 1 of 1822 is still valid, this being the section that covers the classification, the nature of the performance testing and filter marking. ISO 29463 deals with the test apparatus, test procedures and how the results are interpreted and is, in effect, identical to BS EN 1822 but is designed to be a world standard rather than limited to the UK and Europe. This is particularly relevant to us in light of the Brexit.”

STANDARDS FOR INDUSTRIAL VACUUM CLEANERS

Relating to the two current filter tests and standards are two British standards concerning Vacuum Cleaners for hazardous dusts: BS 5415-2.2:Supplement No. 1:1986 describes “Type H” vacuum cleaners and relates to BS3928 and BS EN 60335-2-69:2012 which introduces “H-Class”, relates to BS EN 1822. Helpfully, another standard; BS 8520-1:2009 describing the correct use of vacuum cleaners for handling asbestos states that “Class H vacuum cleaners are commonly referred to as H‑type vacuum cleaners”,  indicating machines complying with either standard are appropriate.

All the standards have the same objective – to ensure that Vacuum Cleaners used for hazardous dusts have high performance filtration capable of efficiently filtering tiny particles measuring a fraction of a micron.

Currently, BVC Industrial Vacuum Cleaners in our Professional ranges are typically designated Type H units to BS5415 – the standard preferred by MOD and Nuclear facilities, whilst our Greenline models are designated H Class units to BS EN 60335.

A Vacuum Cleaner with a HEPA filter is not automatically classified as Type-H or H-Class; further tests are required on the whole machine before the classification can be confirmed.

Also, the classification of a particular Industrial Vacuum Cleaner does not automatically indicate its suitability or not for a particular application. The weight and consistency of the product greatly influences the choice of unit. For example, there is little sense in choosing a machine with a 100 litre collection bag if the product is heavy – it becomes impossible to safely lift the bag, similarly a machine with a small collection bag will clog and blind almost immediately with a product consisting solely of very fine dust; for this application the bigger the primary filter surface area or collection bag the better.

Some of the Vacuum Cleaners in the BVC Type H range can be supplied with both ATEX and Type H ratings. These Type H + ATEX Industrial Vacuum Cleaners have been endorsed by the Technical Advisory Section of the Defence Infrastructure Organisation ( Authors of Joint Services Publication JSP403 ) as suitable for use within MOD indoor firing ranges as part of a holistic cleaning programme where the hazards are potentially both lead dust and un-burnt propellant.

BVC CV7 - Type H Cylinder Vacuum


CV7 is a development of the original cylinder vacuums. Today it offers a unique solution where a compact Type H vacuum unit is required. Although still available as a stand-alone vacuum cleaner, CV7 is now mainly used as an OEM component to incorporate into other equipment.

Designed to run very quietly, the 3 or 4 stage filtration with in-line turbine allows the exhaust air to be piped away.

Applications include medical equipment, cleanrooms, gloveboxes and other areas where hazardous dusts may be present. The design allows the disposal bag to be removed under vacuum to assist dust containment.
