PVC Side Wall Inlet

The W400 Wall Air Inlet is a versatile, all-season inlet that offers air direction control through the use of its bottom deflector louver. The W400 can be mounted to control airflow through a wall by framing in an opening. The W400 inlet has a bottom deflector louver that is used to direct airflow and, if desired, to shut off the inlet.

• Counterbalanced louver adjusts automatically to fan speed
• Bottom deflection louver is also used to shut off the inlet, giving it a virtually leak-proof seal
• PVC plastic is corrosion resistant and the smooth surface cleans easily
• 400 CFM at .08 SP
