Product Overview
Genuine Nilfisk GM80 GM90 Motor Protection Replacement Filter
This Nilfisk 11730410 polyester motor protection filter is designed for the GM80 and GM90 series, providing a critical barrier that prevents fine particulates from reaching the motor assembly.
As a downstream microfilter that sits between the primary dust bag and the motor housing, it captures leakage dust that can erode fan blades, bearings, and windings over time. This unused OEM filter preserves the airflow characteristics Nilfisk vacuums are known for while helping extend service life in continuous-use environments.
Product Condition
Unused, new old stock in original OEM packaging. Clean and intact with no signs of wear or installation.
Product Overview
The Nilfisk 11730410 is a shaped polyester microfilter engineered for GM80 and GM90 vacuum motor housings. Positioned downstream of the main bag and upstream of the motor, it protects the fan system from abrasive fines that escape primary filtration. In cleanroom, industrial, and high-filtration configurations, this filter functions as a sacrificial stage that maintains suction consistency and reduces long-term motor wear.
Vendor data describe the filter class as a microfilter rated to retain approximately 99.5 percent of 2 micron particles (DOP-tested). It is not a HEPA final filter but an intermediate stage essential for proper multi-stage filtration performance.

Frequently Asked Questions
Is this an OEM Nilfisk filter?
Yes. This is a genuine Nilfisk 11730410 motor protection filter, unused and in OEM packaging.
Is this a HEPA filter?
No. It is a microfilter stage rated for fine particulate retention. HEPA performance requires a downstream certified HEPA cartridge and intact upstream seals.
Where does this filter install?
It fits into the GM80 and GM90 motor housing, positioned between the primary dust bag and the motor to protect the fan and windings.
How often should it be replaced?
Replace when visibly soiled, damaged, or when suction loss persists after changing the dust bag. Regular replacement helps preserve motor performance.
Will this improve suction power?
It maintains designed airflow by preventing particulate buildup in the motor area. A fresh filter helps prevent the gradual performance decline associated with dust migration.
Nilfisk built its reputation on durable, serviceable cleaning systems, and this untouched OEM filter continues that lineage by safeguarding the heart of the GM80 and GM90 vacuums for years to come.
