A sanitary filter removes suspended particles from process liquids to protect pumps, valves, and downstream equipment. Its internal screen retains unwanted solids while allowing fluid to pass through. Proper selection depends on particle size, flow rate, pressure drop, material compatibility, and pipeline connections.
The available construction options include SS304 and SS316L stainless steel, 1–4 inch (DN25–DN100) connections, and 30–165 mesh screens. Screen structures include metal mesh, perforated plate, and wedge wire, with EPDM, silicone, NBR, and FKM sealing options.
Screen Selection and Filtration Performance
A sanitary strainer should match the type and size of particles being removed. Mesh count alone does not define the exact filtration aperture, which also depends on wire diameter and screen construction. Finer screens capture smaller particles but may clog faster and increase differential pressure.
| Selection factor | What to check | Purpose |
|---|---|---|
| Screen opening | Mesh specification and aperture | Determines particle retention |
| Flow rate | Expected flow and solids load | Reduces excessive pressure drop |
| Body material | SS304 or SS316L compatibility | Addresses corrosion resistance |
| Connection | Thread standard and nominal size | Ensures proper installation |
| Seal | Chemical and temperature compatibility | Supports leak prevention |
Inline Protection for Process Equipment
A sanitary inline strainer is commonly installed upstream of pumps, valves, and narrow flow passages to reduce blockage from suspended solids. Installation should allow convenient screen removal and cleaning. A rising differential pressure, where monitored, can indicate accumulated debris and the need for maintenance.
Cleaning frequency depends on particle concentration, operating conditions, and observed pressure changes. The screen, gasket, and connection should be inspected during maintenance to maintain reliable operation.
Compressed Air Requires a Different Filter Design
A sanitary compressed air filter serves a different purpose from a liquid-line screen. Compressed air systems require components rated for gas service and selected for the required air purity and contaminant removal. A liquid filter should not be used for compressed air unless its pressure rating, materials, and design are confirmed as suitable.
Recognizing Screen Fouling in Daily Operation
As particles accumulate on the screen, flow may decline and differential pressure may rise. Matching the mesh opening to the contaminant size and cleaning the screen when fouling restricts flow supports consistent filtration without unnecessary maintenance.
