FHA Series Filter Housings

Compact multi-chamber filter housings for high-purity chemicals

Filter Housings

Two-chamber and four-chamber filter housings are available for parallel or series (in-line) operation. Their compact, non-metallic PTFE and PFA designs offer superior containment and high-flow performance. They fit many filter types, and enable filters to be changed without disconnecting liquid lines. They may be installed with standard fluid connections without use of NPT threads.

White Knight also offers FHU Series filter housings for fluid temperatures up to 210°C (410°F).

Compact Footprint

White Knight’s unique manifold filter head and ports flow to each filter simultaneously to provide greater surface area while eliminating the fixturing and welding associated with typical filter housings, and this results in typical footprint savings of 50%.

Configurable

White Knight offers parallel two- and four-bowl filter housings, each with port options on the front, back, sides, and bottom/top of the filter housing. All housings include inlet and outlet fittings, vent and drains. Our PTFE and PFA filter housing fit standard filter cartridges and sizes offered by your favorite supplier.

Greater Reliability

White Knight filter housings completely remove numerous leak paths by eliminating the necessity to plumb and weld multiple filter housings together. The redesigned O-ring sealing system between the housing head and bowl utilizes two O-rings and an angled sealing load system to maintain pressure and prevent leaks. This means no more costly filter housing leaks in your wet benches and chemical delivery systems.

Cost Savings

Manifolding filter housings together is costly and time-consuming. White Knight parallel filter housings come in a single, compact unit to save valuable space and setup time. Eliminating leaks also improves reliability and prevents costly downtime and expensive cleanup.
