Universal, 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/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.
Select model (above) for dimensions and comparisons to traditional filter housings.

Configuration
Different Outlet Fittings
Please select outlet connection, fitting and size.
Configuration:
*Notes: Pumps with SP2, SP3, or SP5 pressure switch stroke detection come without shuttle valve. Pump operation in timer mode requires end-of-stroke detection (pressure switch) to prevent over-stroking. Operating pumps in timer mode without end-of-stroke detection voids the pump warranty. Do not use fiber optic stroke detection in applications over 135°C
*Notes: Fiber optics are required for operation. Standard configuration comes dual-probe WITHOUT fibers. Please see stroke detect option for fiber optic cables. Pump operation in timer mode requires end-of-stroke detection (fiber-optic stoke detection) to prevent over-stroking. Operating pump in timer mode without end-of-stroke detection voids pump warranty. Pump requires use of the included White Knight quick exhaust valves (QEVs) or QEVs supplied by the customer used with the optional NPT adapter. Operating pump without QEVs voids pump warranty.
*Notes: Proximity switch required for operation. Standard configuration comes WITHOUT proximity switch. Please see stroke detection options to order proximity switch. Pump operation in timer mode requires end-of-stroke detection (pressure switch stoke detection) to prevent over-stroking. Operating pump in timer mode without end-of-stroke detection voids pump warranty. Pump requires use of the included White Knight quick exhaust valves (QEVs) or QEVs supplied by the customer used with the optional NPT adapter. Operating pump without QEVs voids pump warranty.

Configuration:
Notes: CPA includes two liquid fittings and one drain/vent fitting. If liquid or drain/vent fitting styles or sizes are different please define the first fitting, and repeat fitting style and size for any fittings that are different from the previous call out. All fittings will be the same as the last fitting style and size defined.
Different Outlet Fittings
Configuration:
Note: Flow through is 1/8-in. smaller than fitting size.
Configuration:
Notes: If Housing Bowl Fitting styles or sizes are different from Manifold Drain/Vent Fittings, please define the Manifold Drain/Vent Style and Size first (7-8) and use section below to define the Housing Bowl Fittings (9-10). All Housing Bowl fittings will be the same as Manifold Drain/Vent unless otherwise specified.

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/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.
