Delta Breez Ventilation Fans. Perfectly Quiet. Perfectly Green.
Super Low Profile. Super Low Energy Consumption.
Weighing in at less than 5 lbs, the powerful yet compact Delta BreezSlim sets the bar for performance in the popular small fan size of 7.2” x 7.25" x 3.94". Operating at just 1.0 sone, this quiet fan features Delta’s super reliable DC brushless motor, and an LED indicator light so you know it’s running, and a modern grille design. Perfect for retrofit into an existing space or for ceiling mount or wall mount installation (UL listed for both) into your next multifamily or single-family project. BreezSlim breaks the mold of the everyday bathroom exhaust fan.
The BreezSlim SLM50 features innovative DC brushless motor design for long life, low noise, and low power consumption. It's UL approved for ceiling and wall mount installation. LED indicator will be green when power is on.
CFM (Cubic Feet per Minute)
CFM is speed of 'air flow' - the amount of air extracted per minute when the fan is running. The amount of CFM needed is generally related to the size of area ventilated.
Energy Savings
*Calculations based upon U.S. average retail electricity. Actual results may vary.
Sone Level is how loud the fan is to the human ear. Doubling the sone value means doubling the noise. The average 80 CFM bath fan runs at 0.8~2.5 sones. Delta Breez 80 CFM fans run as low as <0.3 sones. At less than 0.3 sones, the fan is virtually silent.

Why is Ventilation Important?
Many of today's homes are airtight and highly insulated, which are good for cost and energy effective temperature control, but terrible for indoor air quality. Without adequate exhausting and exchange of indoor air to the outdoors, the concentration of pollutants indoors is often many times higher than that of the outdoors. To improve indoor air quality, pollutants must be exhausted, indoor air must be replaced by fresh outside air, and moisture must be controlled. This is best accomplished using ventilation systems.
