The Communicator III
A truly portable, dual input, pressure reading instrument

Know Exactly When To Change Your Filter Element

Change your filter bag before it's completely dirty, and you're wasting money. Wait too long, and you reduce the efficiency of your system with clogged filters. Using Rosedale’s COMMUNICATOR III, you’ll know exactly when your filter element needs changing.

Communicate Intelligently
Starting with our standard, high-quality filter housings, we add an electronic indicator that will signal when pressure drop across the filter is too great. This indicates that your filter element is clogged with dirt and requires changing or cleaning.

• LED warning light when differential pressure reaches 15 psid
• Fully portable, no external power required
• Powered by two long life 9VDC lithium batteries, with 2 to 4 year battery life under normal use AC adapter for continuous read mode
