## Description

Master Flow whole house Fan, belt drive, model: 30BWHFS, 30 in blade, 6000 cfm, 1/3 hp power, 120 V, 4 a, 2 speeds, 3 blades, aluminum blade, 34 in overall height, 11 in overall width, 34 in overall depth, includes: seal-tite white aluminum ceiling shutter, installation hardware, plenum boards and easy-to-follow dyer instructions, UL listed.

Review: Good service - Arrived with a damaged shutter. Replaced it quickly. Thanks
Review: Bigger job than expected - It is not a pop and swap job. The way this is secured either calls for working inside the attic --or-- removing a larger bit of ceiling to access the rafters on either side of the new fan because the bracing is above each rafter.

### ⭐⭐⭐⭐⭐ Good service
*by J***S on December 30, 2025*

Arrived with a damaged shutter. Replaced it quickly. Thanks

### ⭐⭐⭐⭐ Bigger job than expected
*by C***E on February 5, 2026*

It is not a pop and swap job. The way this is secured either calls for working inside the attic --or-- removing a larger bit of ceiling to access the rafters on either side of the new fan because the bracing is above each rafter.

### ⭐⭐⭐⭐⭐ Came as described.
*by J***N on July 23, 2025*

Just installed today. Works fine. Insuffucient time to grade product efficiency. Will be able to fully rate product once it has been functioning during the upcoming hot weather.
