• Universal Sensing: Compatible with positive, negative, and differential air pressure setups.
• Standard Connections: Equipped with dual 1/8" NPT ports and 1/4" quick-connect terminals for straightforward installation.

Common Questions

What is the maximum pressure rating for this switch?
The Antunes JD-2 series is typically rated for a maximum pressure of 35" W.C. Always verify your specific system peak pressure before installation.

Can I use this for gas pressure sensing?
This specific model is designed for air and non-combustible gases; it is not intended for use as a primary fuel gas safety shut-off switch.

How do I adjust the trigger point?
The set point is adjusted via the external screw mechanism, allowing for fine-tuning based on the specific inches of water column required for your equipment's sequence of operation.
