• Large variety of sizes and screen options

• Large inventory - typical lead time less than one week

• Large screen surface area reduces maintenance

• Less than 1 PSI pressure loss (clean)

• Minimize operating costs• Simple, reliable design - no

tight spaces• Flush particles via bottom

flush port• High quality stainless steel

construction (type 304 or 316)

Unlike conventional strainers, the Thompson Series uses an inverted strainer basket. This allows heavier solids to settle in a collection chamber in the housing bottom, below the screen, resulting in longer filtration run times. The bottom flush port allows removal of the settled solids without interupting downstream flow. An optional automatic flush valve removes the settled solids at field adjustable timed intervals. The optional pressure differential alarm package lets you know when the filter needs to be cleaned.

Completely customizable to fit your filtration needs.

PRESSURE DIFFERENTIAL ALARM PACKAGE (PDA)

The Pressure Differential Alarm Package (PDA) continuously monitors the pressure drop across the

internal conical screen. When the strainer screen becomes dirty, the switch-gauge triggers an

audible and visual flashing alarm, intended to alert maintenance personnel when the screen needs

to be removed from the housing for manual cleaning. At maximum flow, all Thompson Strainer

models operate with less than a 1 PSI pressure loss (when clean). The alarm is factory set to

engage when the differential pressure reaches approximately 7 PSID; however, this setting is

adjustable by changing the set point contact at the base of the differential pressure gauge.

The PDA package comes standard with auxiliary contacts for remote monitoring of the alarm.

The PDA is housed inside a NEMA rated enclosure and comes with a 110V / 12VDC wall mount

power supply.

AUTOMATIC TIMER FLUSH PACKAGE (ATF-EA-1.5)

The Automatic Timer Flush Package (ATF-EA-1.5) automatically purges particles that have gravitated

down into the debris reservoir at the base of the strainer. Purging the reservoir; however, does not

clean the internal screen (see above PDA explanation). Depending on the solids’ loading of the

application, the user simply dials in the FLUSH FREQUENCY (time between flushes) and

FLUSH DURATION (length of flush) of the valve. The flush frequency is preset for (24) hours and the

flush duration is preset for (8) seconds; these settings can be substantially changed. Based on the

parameters programmed, the robust stainless steel ball valve opens and closes. The user can

override the timer by engaging a manual flush cycle.

The controller attached to the valve is housed inside a

NEMA enclosure. If ordered with the PDA alarm

package, an electrical cord from the PDA supplies

power to the ATF-EA-1.5 valve package. If the

ATF-EA-1.5 is ordered separately, a 110V / 12VDC

wall mount power supply is included.
