1. Introduction
This manual provides essential instructions for the proper installation, operation, and maintenance of the Dri-Eaz Velo and Velo Pro HEPA Filter Kit, model F518. This kit is designed to enhance air quality by capturing microscopic particles when used with compatible Dri-Eaz Velo and Velo Pro air movers, including models F504 and F505. Please read this manual thoroughly before use to ensure safe and effective operation.
2. Safety Information
Always observe basic safety precautions when handling and installing the filter kit. Ensure the air mover is unplugged from the power source before performing any installation or maintenance. Do not operate the air mover without the filter kit properly installed if air filtration is required. Keep filters dry and free from damage.
3. Setup and Installation
The Dri-Eaz Velo and Velo Pro HEPA Filter Kit F518 is designed for easy integration with compatible Dri-Eaz Velo and Velo Pro air movers (e.g., F504, F505).
- Prepare the Air Mover: Ensure the air mover is turned off and unplugged from the electrical outlet.
- Access the Filter Compartment: Locate the filter housing area on your Velo or Velo Pro air mover. This is typically on the intake side.
- Install the HEPA Filter: Carefully insert the cylindrical HEPA filter into the designated slot. Ensure it sits securely and creates a tight seal to prevent air bypass.
- Attach the Prefilter Cover: Place the prefilter cover over the HEPA filter. This cover helps protect the HEPA filter from larger debris and extends its lifespan. Ensure it is properly seated and secured.

Once installed, the air mover is ready for operation with enhanced air filtration capabilities.
4. Operating Instructions
After the HEPA Filter Kit F518 is correctly installed, operate your Dri-Eaz Velo or Velo Pro air mover according to its specific operating manual. The filter kit works passively to clean the air as it passes through the air mover.
- Air Filtration: The HEPA filter captures 99.97% of airborne particles 0.3 microns or larger, including dust, mold spores, pet dander, and other allergens.
- Applications: Ideal for use in environments requiring improved air quality, such as during water damage restoration, construction, or general dust control.
- Monitoring: Periodically check the airflow from the air mover. A noticeable decrease in airflow may indicate a clogged filter requiring maintenance.
5. Maintenance
Regular maintenance of your HEPA Filter Kit F518 ensures optimal performance and extends the life of your air mover.
- Filter Inspection: Inspect the HEPA filter and prefilter cover regularly, especially after use in dusty environments.
- Prefilter Cover Cleaning: The prefilter cover can be gently cleaned with a vacuum cleaner or by shaking off accumulated debris. Do not wash the HEPA filter.
- HEPA Filter Replacement: The HEPA filter is not washable and must be replaced when it becomes visibly dirty, airflow is significantly reduced, or odors persist. The lifespan of the HEPA filter varies depending on usage and environmental conditions.
- Storage: When not in use, store the filter kit in a clean, dry place to prevent contamination.
6. Troubleshooting
If you encounter issues with your HEPA Filter Kit F518, refer to the following troubleshooting guide:
