Key Features
Three Functions in One
Combines air separation, dirt separation and ferrous-impurity removal, replacing three separate devices.
Magnetic Ferrous Capture
Rare-earth neodymium magnets deliver roughly 2.5x the ferrous removal of a standard separator.
5 Micron Dirt Removal
An internal screen coalesces micro-bubbles while capturing non-ferrous debris down to 5 micron.
Removable Magnet & Blowdown
Captured debris is purged through the drain valve online; the magnet is removable for cleaning.
12 In Ansi Flanged Connection
12 in ANSI flanged connection sized for the application.
Steel Construction
Steel body with stainless and EPDM internal components for hydronic service.

Frequently Asked Questions
This DISCALDIRTMAG adds dirt separation to 5 micron and magnetic capture of ferrous particles, while a DISCAL removes air only.
The rare-earth neodymium magnet delivers roughly 2.5 times the ferrous-impurity removal of a standard air and dirt separator.
No. Captured debris purges through the drain valve while the system stays online; the magnet is removable to release ferrous particles during blowdown.
