Capture, clean, expel: how Ronningen-Petter systems from Eaton work
Every process is unique - that’s why we offer several backwashing/tubular systems in several configurations.

Our flagship tubular systems. During backwash, a single tube is taken off-line from the process flow via a three-way valve. Once an element is clean, it is returned to service and the next element may be cleaned. The remaining elements in the filter remain operational throughout this cycle. F-Series and AFC-Series multiplex units consist of 2-20 individual tubes valved in parallel to common inlet, outlet, and drain headers. AFC-Series units are also available in economical single and duo-tube configurations, which must be removed from service for manual cleaning.

AFC-Series - high-pressure capability and modular flexibility
When your application demands high-pressure operation - up to 1,000 psi (69 bar) - and scaleable flexibility, the Ronningen-Petter AFC-Series is optimal. AFC-Series systems are available in single-, duo-, and multiplex configurations to meet your application and business demands.

Multiplex Filters
Multiplex units consist of two or more single filter units valved in parallel to common headers. This configuration enables sequential backwashing of individual elements while the system remains in operation.

AFC 2200 available in 1000 psi (101.3 bar) only.

Cake Formation Increases Operational Efficiency

N/A While the filtration media provides some of the filtration action, collected contaminants actually further increase efficiency. We call this phenomenon "cake formation." The collected solids (or "cake") trap additional contaminants. The key to making this principle work is timely cleaning - too soon and you lose the benefit, too late and the system flow becomes hindered.

Ronningen-Petter systems come factory pre-set to backwash when the differential pressure from inlet to outlet reaches 15 psi (1 bar) - typically the optimum time to initiate backwashing, although this is adjustable.

Internal and External Backwashing Configurations

N/A Ronningen-Petter AFC-Series tubular multiplex systems are available in both internal and external backwashing configurations. Internal backwashing systems are designed for processes with system pressure greater than or equal to 45 psi (3.1 bar) and low viscosity process liquids. External backwashing systems are designed for applications with high-value process liquids and/or processes with low operating pressures.
