Manifold Heads Configured for Your Foodservice Filtration System

One cartridge, all the water

A single-head manifold routes all incoming water through one cartridge before it leaves the manifold. There is nothing to split and nothing downstream for the water to pass through again: the cartridge installed is doing the entire job. It is the simplest arrangement in this lineup, and the most straightforward to service because there is only one cartridge to track and change.

Best for: Lower-volume applications, a single piece of equipment, or any spot where one cartridge's flow rate and capacity are enough.

Two cartridges sharing the load, in parallel

A twin manifold splits incoming water across two cartridges running side by side, then recombines the two streams on the outlet side. Each cartridge only treats its own share of the flow. Splitting the load this way raises the combined flow rate the manifold can support and stretches the combined capacity before either cartridge is due for a changeout, while the level of filtration each gallon receives stays the same as a single cartridge would provide.

Best for: Equipment or a location that draws more water than a single cartridge comfortably supports.

Three cartridges in parallel, higher combined flow

A triple manifold splits incoming water across three cartridges running side by side and brings the three streams back together on the outlet. Each cartridge only carries a third of the total flow, so the bank as a whole supports more combined volume and more combined capacity before a changeout than a single cartridge could. The filtration each gallon receives does not change; what changes is how much water the manifold can move.

Best for: Higher-draw equipment lineups or sites where flow demand has outgrown a twin manifold.

Four cartridges in parallel, the largest bank

A quad manifold divides incoming water across four cartridges running side by side and recombines the four streams on the outlet. Splitting the load four ways is how this family supports its highest combined flow rate and its longest combined capacity before any cartridge needs changing. Each gallon still only passes through one cartridge; the four positions exist to carry more total volume.

Best for: The highest-draw sites in the lineup, where even a triple bank would be undersized.

One cartridge, then a second in series to polish

In a 1+1 manifold, all the water passes through the first cartridge, then every drop of that same water passes through a second cartridge downstream before it leaves the manifold. Nothing is split: the two cartridges are in series, so the second one is a polish stage that adds a further treatment step rather than added flow capacity. It is a way to layer two different jobs, for example a sediment stage ahead of a taste-and-odor stage, onto one water stream.

Best for: Applications that need a second treatment step on the full flow rather than more volume.

Two cartridges in parallel, then a polish stage

A 2+1 manifold pairs a two-cartridge parallel bank with one more cartridge in series downstream. The parallel pair splits the incoming water and supports higher combined flow and capacity; the water then recombines and every gallon passes through the third cartridge as a final polish step. One manifold delivers both added flow support and an additional treatment stage.

Best for: Sites that need the flow support of a two-cartridge bank plus one more treatment step on the full stream, such as a dedicated scale-reduction or taste stage after the main filtration.

Three cartridges in parallel, then a polish stage

A 3+1 manifold splits incoming water across three cartridges running side by side, recombines the flow, then runs every gallon through a fourth cartridge in series. The three-cartridge bank carries the flow rate and capacity; the fourth cartridge downstream is a polish stage the whole recombined stream passes through once, adding a treatment step rather than more volume.

Best for: Higher-flow sites that also need a dedicated final treatment stage, such as scale reduction, on the combined output.

Four cartridges in parallel, then a polish stage

A 4+1 manifold is the largest configuration in this family: four cartridges run side by side to carry the flow, and a fifth cartridge sits downstream in series, treating the full recombined stream one more time before it leaves the manifold. The parallel bank gives the manifold its flow rate and capacity; the fifth position is a dedicated final stage every gallon passes through.

Best for: The highest-draw sites that also require a dedicated final treatment stage on the entire flow.

105220   BGX 1+3 Stage Manifold, 3/4 in NPT Inlet, Pressure Gauge, No Rinse Valve

The 105220 is a four position BGX manifold, 22.283 inches overall, with a 3/4 inch NPT inlet and 3/4 inch NPT elbow fittings. It carries a pressure gauge and no rinse valve. The full incoming stream passes through a single first stage, then divides across a three cartridge parallel bank.

Port connection: 3/4 inch NPT. Contact Customer Service before specifying.

105221   BGX 1+1A Manifold, 1 in NPT, Rinse Valve and Pressure Gauge

The 105221 is the 1+1 arrangement built on 1 inch NPT connections rather than the standard 3/4 inch, with a rinse valve and pressure gauge. The engineering drawing shows the same two head layout and the same series crossover as the 105216, so the water path is identical; the A designation marks the larger port size and the alternate outlet fitting.

Port connection: 1 inch NPT. Contact Customer Service before specifying.
