Product information "Belimo 01APS-10R.1 Differential Pressure Switch (20…300 Pa)"

The Belimo 01APS-10R.1 is an adjustable differential pressure switch for monitoring overpressure, vacuum, and differential pressure in air and other non-combustible, non-aggressive gases. It is commonly used in HVAC applications such as filter dirty indication, fan status proving, and airflow/duct pressure supervision.

This model covers a switching range of 20…300 Pa, with a durable enclosure suitable for standard AHU/plantroom environments.

HVAC applications

Air filter monitoring (clean/dirty filter indication)
Fan proving (confirm airflow / pressure rise)
Duct static pressure supervision
Air handling unit (AHU) safety interlocks
General airflow/pressure switch duties in BMS/controls
