The DEL-AIR design is based on the use of exhaust fans, fresh air inlets, heat exchangers and controls to achieve a negative pressure ventilation system. Equipment engineered to the highest standards guarantees optimum environments for production and worker health.
Northwind Fans       DEL-AIR exhaust fans are conveniently named for their air moving capacity to simplify selection and sizing. Six sizes to choose from deliver 750 to 20,000 cfm. All Northwind fans come with the trademark engineered weather hoods, ensuring the fan will perform in all weather conditions.
Durability       DEL-AIR's reputation for durability comes from well-engineered construction of polyethylene, stainless steel, nylon, and other corrosion-proof materials. These fans can be used for exhaust or re-circulation in a wide variety of configurations
Inlets       DEL-AIR inlets are made to last. Inlets have never been so trouble free!       DEL-AIR manufactures three styles of reliable and effective inlets - DEL-AIR HiFlo inlets, DEL-AIR wall inlets, and DEL-AIR ceiling inlets - all designed to supply the correct air pattern for your animals' comfort.       The simple, effective design allows fresh air to enter the barn with ease. A spring balanced extruded polystyrene baffle adjusts air flow automatically as fan speed and negative pressure changes. To adjust to unique barn conditions, DEL-AIR inlet slide adjuster is used to control the volume and speed of incoming air. With a simple adjustment, you can vary the amount of pressure needed to allow a specific volume of air into your environment.       DEL-AIR also offers the option of cable control for all styles of DEL-AIR inlets.

Single Room Controls       DEL-AIR controls have easy-to-read display faces with optional digital readouts for dim lighting conditions. Tailor your controls to your needs by opting for model features that include: second stage relay for heating or cooling; combination variable speed/ single speed control; built-in alarm signals for temperature spikes, power failure, or low line voltage; and a variety of programming options.
Heat Recovery Ventilator       HRVs offer you a fresh look at an energy management tool that is dust free, freeze-resistant and easily maintained. Winter ventilation is necessary to provide fresh air, remove manure gases and control unwanted moisture buildup. You can accomplish this by using exhaust fans and supplemental heat, however, excessive energy costs make this expensive. A DEL-AIR HRV will reduce heating costs dramatically when ventilating buildings in the coldest subzero weather. The principle that makes this possible is 'heat transfer'. DEL-AIR's patented energy efficient core recovers animal heat that would normally be exhausted, virtually eliminating the need for supplemental heat!
