Category: Automatic Strainers
Series: 98-Series
Model format: `[BODY MOC]98-[INLET/OUTLET SIZE][STYLE]-[SCREEN SIZE]-[SCREEN MOC]-[DESIGN PRESSURE]-[CONTROL LEVEL]`
Example: `S698-12F-500-S6-PT1-L1`

## Overview
Automatic, motorized self-cleaning strainers offering continuous removal of debris while maintaining full-time, uninterrupted flow. Offset inlet/outlet orientation, low pressure losses, and configurable controls allow the unit to adapt to changing process conditions.

## How It Works
Unfiltered fluid enters the strainer through the inlet and flows into the centre of a wedge wire strainer basket.

Particulate collects on the screen as clean fluid passes through.

As differential pressure increases to the setpoint, the cleaning cycle initiates automatically.

An internal scraper (blades or brushes) rotates against the screen, removing buildup and directing it to the bottom sump.

A fast-acting blowdown valve opens to flush out collected solids; clean flow is uninterrupted during the cycle.

Clean fluid exits via the outlet toward the next process stage.

## Applications
- Cooling tower closed loop
- Cooling water, once through (e.g. large Power Gen cooling water intake)
- Pump-seal cooling water
- Firewater pump protection
- Lube oil systems
- Industrial produced water
- Renewable fuel feedstock (coarse screening at offloading), (fine screening downstream)
- Steel mills & foundries, quench water filtration
- Industrial wash stations (protecting spray nozzles)
- Produced water & salt water disposal (SWD)
- Specialty designs available for SWD service
- Pulp & paper
- Miscella filtration & separation (-50°F methanol service)
