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 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 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.
