Product Overview
A.J. Antunes 8021204014 Differential Vacuum Air Pressure Switch
The A.J. Antunes 8021204014 Differential Vacuum Air Pressure Switch monitors air pressure in HVAC systems. This switch can be adjusted between 0.17" water column and 6.0" water column. When air pressure goes above or below the set water column, the switch will trip. This causes the equipment, or another part in the system, to either turn on or turn off. This keeps the system safe from failing.
