Supco NPC112H Negative Pressure Trap 1.5" x 1.5" Clear Horizontal Mount

The Supco NPC112H is a clear PVC negative pressure condensate drain trap designed for HVAC equipment operating under negative pressure conditions. This horizontal-mount trap allows liquid condensate to drain efficiently from the system while preventing air from entering or escaping the equipment, maintaining proper system operation and efficiency.

Key Features:

• 1.5" x 1.5" connection size for standard drain line applications
• Clear Schedule 40 PVC body for easy visual inspection of condensate flow
• Horizontal mounting configuration for versatile installation options
• Operates effectively in both wet and dry conditions
• Prevents air infiltration and loss in negative pressure HVAC systems
• Allows condensate to drain continuously without system disruption

This negative pressure trap is essential for maintaining the proper function of air handlers, fan coils, and other HVAC equipment where condensate must be removed while preserving system pressure integrity. The clear body construction allows technicians to quickly verify proper drainage and identify any potential blockages during routine maintenance.
