Velum protective filters have been designed by ​​Nitty-Gritty in order to protect electronic equipment, such as compressors and electric motors, from oily mist and dust produced in industrial manufacturing facilities.

Velum protective filters


Velum Standard
Velum protective filters are applied directly to the external entrance grid of ventilation and cooling unit systems. Once applied, Velum holds dust and oily mist in its patented knitted fabric which protects the inner filter and allows fresh, clean air through the equipment. To ensure the best efficiency of your equipment, replace Velum once a week.

Velum Air
Velum Air has a thicker fabric but lower porosity and is designed to ensure better airflow and prevent overheating. It is ideal for compressors, cooling systems, and heat exchangers.

Velum XL
Velum XL is larger to fit heat exchangers, conditioners, compressors, or related equipment. Velum XL is thicker but more porous for better airflow without overheating. Velum XL captures dust and dirt before it enters your equipment. Protect your investment and reduce maintenance costs with Velum XL.

Velum Motor
Velum Motor is the perfect solution for the protection of electric motors. The patented system and reusable polypropylene support can be easily applied with a magnet and a normal O-Ring (included in the package).
