## FAQs

### When should I choose an HFH horizontal housing?
Choose the HFH when vertical headroom is limited. The horizontal design with side access allows installation in confined spaces while maintaining easy cartridge change-out.

### What cartridges fit the HFH housing?
The HFH is designed for 6.5" OD high flow cartridges with outside-to-inside flow and 338 O-ring seals, including Fil-Trek HF Series and compatible high flow elements.

### What internal linings are available?
HFH housings can be lined with ceramic, epoxy, PFA, ETFE (Tefzel), ECTFE (Halar), PVDF (Kynar), or rubber for corrosion protection in aggressive chemical applications.
