A good ventilation system is an important consideration in any commercial or industrial building, and wall and ceiling inlets provide an effective fresh air solution. These air inlets allow the incoming air to be warmed and mixed with the existing air in the building, avoiding cold, uncomfortable downdrafts. They're commonly used in agricultural facilities, including greenhouses and hog, poultry, and dairy barns. 

With the right weather hoods for your air inlets, your building receives the fresh air it needs while staying protected from even the harshest winds and severe winter weather. Take a look at our inventory of innovative ceiling inlets from J&D Manufacturing, an industry leader that has long specialized in agricultural and industrial ventilation:

About Ceiling Inlets

There are a variety of ceiling inlet styles to choose from, but they all have a few things in common:

  • Durable and built to last

  • Easy to install

  • Easy to clean

  • Insulated to minimize condensation formation

  • Doors designed to direct air across the ceiling rather than drop it down on the animals

  • Innovative product design from a company that understands the industry and your unique needs

From there, you can choose the model that best suits your facility. These are just a few of the many options we have in stock:


This model has single-stream inlets for one way direct airflow or dual-stream inlets for double sided direct airflow. The heavy-duty PVC body and stainless-steel corner frame braces provide durability and reliability, and adjustable counter balanced doors operate automatically as the static pressure increases in the building. 


The IC44F ceiling inlet features European style doors for enhanced performance. With sealed inlets and foam-filled insulation, these air inlets are energy efficient, corrosion resistant, and easy to clean with a high pressure washer. 


The wall series of air inlets are equally durable and easy to install. They're lightweight and made smooth to minimize air resistance. Different models are designed to aim and project air differently to suit your ventilation needs. The TPI-1800-VFG-C-Y is a smaller wall inlet option. 

Depending on your chosen air intake model, you may see a selection of compatible weather hoods to choose from before you make your purchase. You'll also notice a variety of information, including product catalogs and brochures, photos, descriptions, and availability and lead time, listed with each ceiling inlet. This is to help you make an informed purchase, which is part of how we ensure you get the HVAC products you need as quickly as possible. 

For agricultural facilities, fresh air intake is essential for the comfort of your animals and, ultimately, their health and performance. Finding the right solution is key to a successful operation.
