4-inch Rack System

The 4 inch Rack System is versatile, easily installed, and adapts to various exhaust fans. The custom manufactured filter (aka “pillow”) is inside the rack. The rack has a built in drain that allows water to pass through the system at a high volume. After the initial installation of the rack, only the pillow needs to be replaced during regular scheduled hood cleanings depending on the volume of the restaurant. The pillows are inexpensive making this option one to consider for your restaurants.

For high volume/high grease producing fans, we recommend using our 7 inch System.

Rack Systems come ready to install, including filters, and mounting holder, and our new deflector shield.

Replacement Filter

Each 4 Inch Rack System comes with a custom DRIPLOC Filter inside. We recommend the filter be changed after each exhaust fan cleaning, however grease exhaust volume will dictate the changing frequency.
