TPI Wall & Ceiling Inlet Valves

Insulated Fresh-Air Inlets for Poultry and Livestock Ventilation

TPI Wall & Ceiling Inlet Valves provide controlled fresh-air intake for commercial poultry and livestock buildings. Manufactured from specialized polyurethane, these agricultural ventilation inlets combine insulating properties with a range of wall-mounted, ceiling-mounted and tunnel ventilation configurations.

Available through County Line Equipment, the TPI inlet range helps producers select the appropriate air intake solution for their barn layout, ventilation capacity and climate-control requirements.

Whether installing fresh-air inlets in a new poultry barn, upgrading a hog facility or planning a tunnel ventilation system, TPI offers multiple inlet sizes, configurations and accessories to support efficient air distribution.

Key Features & Benefits

• Insulated Polyurethane Construction: Specialized polyurethane provides effective thermal insulation, helping reduce condensation concerns around incoming-air openings during cold weather.
• Controlled Fresh-Air Intake: Regulated inlet openings allow incoming airflow to be managed as part of the barn’s ventilation system.
• Wall and Ceiling Installation Options: Multiple configurations accommodate different building designs and fresh-air distribution requirements.
• Multiple Airflow Capacities: Choose from standard wall inlets, ceiling inlets and higher-capacity modular tunnel inlets according to the building’s ventilation needs.
• Cold-Weather Ventilation Support: Insulated construction is particularly valuable in Ontario barns operating through significant seasonal temperature changes.
• Coordinated Inlet Operation: Compatible control arms, pulleys, cables and connection hardware support coordinated inlet adjustment.
• High-Capacity Tunnel Ventilation: Modular 6000 VFG inlets provide substantial airflow for larger ventilation systems and can be stacked to increase total intake capacity.
• Corridor Ventilation Options: The TPI 220-P Corridor Inlet directs incoming air toward the corridor rather than directly onto animals.
• Optional Wind Hoods: Available exterior accessories help accommodate specific installation and weather-exposure requirements.
• Optional Light Traps: Compatible light-control accessories are available for applications where daylight entering the barn must be limited.
• Optional Protective Mesh: Wire mesh options help restrict unwanted bird or pest entry while maintaining an air intake opening.
• Flexible Installation Accessories: Wall liner extensions, closing latches, pulleys and support hardware provide options for different inlet installations.

How TPI Wall & Ceiling Inlet Valves Work

TPI inlet valves regulate how fresh outside air enters an agricultural building.

Step 1 — Fresh Air Enters the Building

Outside air enters through a wall-mounted or ceiling-mounted inlet as the ventilation system creates the required pressure difference.

Step 2 — The Inlet Opening Is Regulated

Compatible control hardware adjusts the inlet opening to accommodate the building’s ventilation requirements.

Step 3 — Incoming Air Is Directed

The selected inlet design influences where incoming air travels. Wall inlets and ceiling inlets use different airflow arrangements to suit the barn layout.

Step 4 — Air Mixes Within the Building

Properly designed air distribution helps incoming fresh air mix with the indoor environment before reaching the animals.

Step 5 — Exhaust Equipment Removes Used Air

Working alongside appropriately sized exhaust fans and climate-control equipment, the inlets form part of a complete agricultural ventilation system.
