Each vessel model or style has specific design features. Please contact us to discuss your application and the most suitable design to suit your needs.

• TBF Design - Featuring a "goose neck" or "over-the-top" inlet design
• SBF Design – Side entry inlet, mid-priced and extensively used for industrial applications
• FBF Design - An entry-level housing for industrial applications

Obtain all the details of the liquid/solid composition. You need to confirm the chemical compatibility to ensure the proper material is used for the bag, housing and seals.

Consider the pH level in order to choose the proper material. Is the product an acid with a pH of 1-7 or is it Alkaline 7-14?

Viscosity is the resistance of a fluid to the motion of its molecules among themselves. Water, ether, and alcohol have low viscosities; heavy oil, glycerin, and syrup have high viscosities. Viscosity affects resistance directly. If all other conditions remain constant, doubling the viscosity in a filter system results in twice the original resistance to flow. Consequently, as viscosity increases, the pressure required to maintain the same flow rate increases. Centipoise is the unit of measurement comparing the viscosity of a fluid with that of water, which has a viscosity of 1 c. p.

The temperature at which filtration will occur can affect both the viscosity of the fluid, the corrosion rate of the filter or housing, and the filter medium compatibility. Viscous fluids generally become less viscous as temperature increases. If a fluid is too viscous, it may be advisable to preheat the fluid and to use a jacketed housing or an electrical heat jacket on the housing. Temperature also has an impact on the selection of filter media and the O-ring seals.

For example: In an application with a low flow rate and a high solid loading it may be preferable to oversize the unit providing a greater surface area and dirt holding capacity. The increased surface area provides reduced pressure resulting in increased filter life.

Crystalline solids can form a permeable layer on the filter media and gelatinous solids can form an impermeable layer that will cause blinding off of the filter media.
