Numatic HZ370 Hazardous Dust  Vacuum Cleaner H13 Filtration 

The HZ370 is essential for anyone who works in places that has the potential of hazardous dust being present (Silica Dust, Asbestos) . The H13 Hepa filtration system offers 99.95% filtration efficiency, keeping collected fibres & H Class dustsafely contained within the vacuum. 

Like other numatic models the 370 stands for drum size in the case the this drum provides a generous 15Litre capacity without being to big to get into confined areas but still allows for alot of capacity to be used.

What makes the HZ370 different from a normal numatic vacuum?

The HZ370 is specially designed to be used to clean up hazardous dust or materials which a normal machine will not be able to do without the H13 FIltration, the vacuum is fitted with a H13 Hepa Module which ensure 99.95% filtration is collected, these main filters can last up to 3-5 years before requiring replacement of the filter..

How durable is the HZ370?

The drum on this machine is made from a durable plastic similar to that used in the commercial machines in the Numatic range, it is hard wearing and will stand up proper use without any issues. 

All the accessories are the same as those used in the industrial grade machines in the Numatic range and are therefore more than strong enough to stand up to daily use on site. 

The head of the vacuum cleaner is made from steel and features NuCable technology, this makes the mains cable very easy to replace as it is similar in style to a Kettle type lead. 

How do I know what grade of a machine I need?

It is not always obvious which materials are hazardous and which are not, we ALWAYS recommend having a full risk assessment carried out on site before purchasing a machine. This will tell you what grade of vacuum is require H class machine is needed. We also advise to go with a H Class even if only M Class dust is present to ensure full filtration just incase there is any H Class present.

What accessories come with the HZ370?

  • Included Accessories - The vacuum is supplied with a full set of hand tools, spare secondary filter, dust bags and waste bags to, this allows for most cleaning tasks to be complete. 
  • Optional Accessories -  We offer an optional secondary floor tool kit that makes floor cleaning much easier, this is especially convenient for cleaning down at the end of the day on-site or in a workshop.

Regardless of which kit that you opt for the vacuum comes supplied with all that is needed to carry out the most common cleaning tasks right out of the box.

What bags should I use with the HZQ370?

The NVM-2BH are the correct bags to use with this vacuum cleaner, 10 bags come included with the machine out of the box. They provide the first 3 layers of filtration and make the vacuum cleaner and safer to empty by containing the waste. Additional bags can be found here

How do I ensure that no waste escapes the machine during transit?

The vacuum is supplied with screw on dust caps for both the drum and head, these allow the vacuum drum to be sealed off when the machine is not in use or in transit, preventing any hazardous material escaping the machine.

What certification does the HZQ370 come with?

Every HZ 370 is tested before leaving the Numatic factory and is supplied with the appropriate certification to show that it is suitable for the intended application. 

What is the difference between the HZ370 and HZQ370?

You will notice that some places refer to the HZQ370 as the HZ370, they are both the same machine. Numatic updated the name system for these machines in 2014 from HZQ to HZ.

ASH Chimney Sweep 10/06/2020

Fantastic piece of kit. It's light weight, quiet and very powerful suction. Ideal for domestic chimney sweeping.

MC 13/05/2020

Excellent vacuum. Best thing with this machine is the low noise level, and the exhaust vent in the top which can be used with a hose to duct the air outside.
