Description
The A.J. Antunes 8024202041 is a genuine OEM air pressure switch designed to monitor and control air or differential pressure in commercial HVAC and mechanical systems. It provides reliable pressure sensing and actuates a control circuit when the sensed pressure passes a preset threshold.
Key Features
- Pressure range: approximately 0.17″ – 1.0″ W.C. (water column) — ideal for many low‑pressure air sensing applications
- SPDT (Single‑Pole, Double‑Throw) switch contacts provide dependable on/off control for equipment logic or safety interlocks
- Connection sizes: 1/4″ male NPT and 1/8″ female NPT ports for standard pneumatic tubing
- Compact, durable design engineered for long‑term service in HVAC controls and industrial equipment
- Commonly used in air handlers, blower circuits, duct pressure monitoring, and similar applications where low‑pressure detection is required
