NVM 1CH Hepaflow Dust Bags
Numatic NVM-1CH HepaFlo dust bags are replacement consumables for machines that specify this bag fitting. Keeping suitable replacements beside the vacuum helps teams change a full bag promptly and prepare for the next cleaning round.
The clearly identifiable NVM-1CH reference is useful in shared cleaning cupboards. Check the complete machine model and instructions when choosing stock, particularly where similar-looking vacuums use different bag sizes.
Layered Material and Self-Seal Closure
The three-layer material supports filtration and airflow during dry collection. It forms part of the vacuum’s collection arrangement, working alongside the separate filter specified for the machine.
A self-seal tab closes the inlet when the used bag is removed, helping contain the contents during handling and disposal. Replace the filled bag as directed and keep unused bags clean and dry until needed.
Compatible Stock for Routine Machine Care
Match the bag specification to the vacuum rather than choosing by appearance alone. HVR200, HET160, PSP180, NVQ240 and NQS250 are examples that use NVM-1CH, subject to the exact model instructions.
Plan bag changes alongside checks of the hose, floor tool and filter. Keeping those checks together helps the cleaning team investigate reduced pickup and prepare the machine for the next room or shift.
The NVM-1CH code is particularly useful when a cleaning cupboard contains several similar-looking Numatic vacuum cleaners with different bag requirements.
These bags are intended for dry collection. Their use does not turn a dry machine into a liquid-recovery vacuum or change its approved dust classification. Use our Numatic vacuum accessories range when other compatible parts need attention.

Ideal Applications

- Regular cleaning rounds in offices, shops and schools.
- Hospitality cleaning cupboards with identified machine consumables.
- Planned bag changes and routine vacuum servicing.
Directions for Use
- Check the bag code: Read the vacuum's model label and instructions to confirm NVM-1CH compatibility. Switch the machine off and unplug it before opening the head or changing consumables. Follow the machine-specific removal procedure.
- Remove and close the used bag: Detach the bag carefully from the inlet connection without tearing it. Close the self-seal tab and handle the bag gently to contain its contents. Dispose of the collected material according to the site's waste procedure.
- Fit the replacement: Seat the new bag securely on the inlet as shown in the vacuum instructions. Arrange it in the drum without trapping it under the rim, then refit the required filter and machine head before restarting.
- Check during routine use: Inspect the bag regularly and change it before overfilling. If pickup falls, switch off and unplug before checking for a full bag, dirty filter or blocked tools and hose. Keep unused bags clean and dry.
FAQs
Will they fit every Henry or Numatic vacuum?
No. Match NVM-1CH to the exact machine instructions. HVR200 and HET160 are examples that use this specification, but other Numatic machines use different bag sizes, so a family name or similar appearance is not sufficient.
Are NVM-1CH and NVM-2BH interchangeable?
They are different bag specifications. Select the code stated for your machine rather than choosing by packaging colour or a related-product suggestion. Ask Astral Hygiene for help if the model label or required code is unclear.
Do HepaFlo bags give my machine a HEPA rating?
HepaFlo is the bag range name. Fitting a bag alone does not establish a HEPA filter rating or hazardous-dust approval for the complete vacuum; use the filtration system and equipment specified for the task.
Can I use these bags for wet pickup?
No. They are for dry collection. If a compatible wet-and-dry machine is being changed to liquid pickup, follow its instructions for the correct wet setup and removal of dry-collection components.
When should I replace a bag?
Check it regularly and replace it before it becomes overfilled. Reduced pickup may also indicate a blocked hose or tool, or a filter needing attention, so unplug the machine and investigate those causes rather than assuming the bag is always responsible.
How does the self-seal tab help during replacement?
It closes the bag inlet after the bag is detached from the vacuum, helping contain collected dust. Handle the used bag gently, follow the machine’s removal procedure and dispose of the contents according to the site’s waste arrangements.
