Introducing the Sparkler® Reverse Flow Horizontal Plate Filter (RF)—a proven filtration solution engineered to meet the highest standards of efficiency, cleanliness, and product recovery. Designed specifically for industries requiring zero-heel filtration and stringent sanitary conditions, the Reverse Flow RF sets a new benchmark in filtration efficiency.
Eliminates residual heel, ensuring complete product recovery and zero waste. This feature makes the Reverse Flow RF ideal for processes where every drop matters.
The reverse flow design ensures the vessel remains clean after filtration. With all filtrate solids contained within the cartridge, cleaning is quick and efficient, reducing downtime and labor. Additionally, all filter components are either disassemble-able or fully welded for easy cleaning and maximum hygiene, making this filter perfect for industries with strict sanitary requirements.
The innovative flow path directs the filtrate from the center column through the filter plates and into the filter tank, achieving superior filtration efficiency and consistent performance. This inside-out filtration design offers distinct advantages, particularly in applications requiring max throughput and cleanliness.
Available in a wide range of materials such as 304 S.S., 316 S.S., Hastelloy C-276, and more, the Reverse Flow RF can be customized to handle various chemical environments and process demands.
Unlike the Standard Flow filter, the Reverse Flow RF does not require venting in many operations, simplifying the process and improving efficiency.
With over 2,500 Sparkler® Reverse Flow Filters in operation worldwide, our filters have been tested and proven across hundreds of unique applications. The Reverse Flow RF’s sanitary and zero-heel design enables it to excel in industries such as pharmaceuticals, resins & epoxies, chemical , precious metal recovery, polyol, food & beverage , and any application where “Every Drop Matters.”
It is also used in solids collection applications where the solids put up too much resistance to build a thick cake on a single plate, requiring multiple plates instead. Containing the solids within the filter cartridge in the RF configuration is a viable option when a Nutsche is not feasible.
Curious if we’ve handled your specific application? With decades of expertise, the answer is almost always “yes.” Contact us today to discuss how the Reverse Flow RF can meet your needs.
