Numatic 604116 Primary Permatex Filter

Genuine Replacement Filter for many machines, including James, Hetty, Henry, NRV200, PSP Range, NSP Range, George, and many more. If you have a 356mm vacuum cleaner from Numatic and are finding the suction is not as good as it once was, and have already replaced the bags it may be time to change your secondary filter. This basket filter is the last stage of filtration after your dust bags in your vacuum cleaner, it sits on top of the drum and prevents dust from escaping the vacuum cleaner and protects the motors from foreign objects. If this filter becomes dirty and blocked it can reduce the suction of the vacuum cleaner and it needs to be replaced.
