Highlights

  • Air inlets and tunnel doors provide precise control and distribution of airflow into or out of any type of ventilation system.
  • Energy savings and low maintenance.
  • Power washer friendly.
  • Corrosion resistant construction.

Built to Perform

Actuated Ceiling Inlets

Actuated ceiling inlets are available in a 2500 to 4000 CFM bi-directional or 2500 CFM uni-directional models and with stainless steel or plastic housings.

Actuated Ceiling Inlets

Cut to length on site for a customized-fit

Actuated PVC Wall Inlets

Opens automatically based off negative static pressure supplied by the exhaust fans. Available in bi-fold or four-sided models for ceiling inlets, and in top-hinged counter-balanced model for wall inlets. Corrosion-resistant plastic and aluminum housing and doors. Hardware package and insulation stop with every inlet. Panel dimensions are 1.5″ thick x 30″ tall x 24’ long.

Actuated PVC Wall Inlets

Adjust-A-Baffle™ Systems

Constructed of one-inch thick polystyrene with a rugged plastic coating fastened to UV-stabilized PVC channels. Any length possible in 8″, 12″, 16″, 18″, and 24″ sizes. Flexible PVC hinge and sealing strip slide into the PVC channels. Stainless steel cable or rod hardware packages available.

Adjust-A-Baffle™ Systems

Bi-flow ceiling inlet sizes: 1000 & 2700 CFM

Non-Actuated Ceiling and Wall Inlets

Non-actuated ceiling and wall inlets models are available with plastic or aluminum housing. The counter-weighted baffle system allows the 12″ baffle to become automatic without the use of mechanical static pressure control.

Refer to the actuator manual to set limit switches in the actuator for the proper amount of travel needed.
If the pulley ratio is 1:1 the travel needed in the actuator is the same as the maximum opening listed above.
If the pulley ratio is 2:1 the travel needed in the actuator is twice the maximum opening listed above.
