The new FLN Inline Filters and FLND Inline Duplex Filters from HYDAC have built-in quality protection (QPD) to prevent the use of non-quality protected filters in your machines. The proprietary design from HYDAC has a unique interface between the filter and filter element. This design feature prevents the use of inferior filter elements from counterfeit sources and ensures high-quality elements are installed on your equipment.
Dangers of Using Non-Quality Protected Filters
Counterfeit sources of filter elements have no regard for quality, performance, critical component protection, production downtime or system repair costs. Their non-quality protected filters can result in a catastrophic failure of your filtration system and machine downtime for repairs. Below photos show a pirated version of a replacement filter element and the results after use.
