Product Details ＋

Description

Duct Filter Box: This product is engineered for use with inline fans, enabling fresh air circulation and blockage of dust and odors. It is constructed with 1mm thick cold-rolled steel alongside aluminum duct flanges, ensuring durability and the ability to withstand extreme weather conditions.

Efficient Design Features: A slide lock door offers easy accessibility to the inner chamber, while its soft neoprene layer serves to create a dust-free seal. The box comes with a standard high efficacy filter that effectively traps particles like dust, dirt, lint, and odor.

Dimensions and Capabilities: The duct filter box measures 23.46 x 8.42 x 11.73 inches, fits 4” inline fans, offers 400 CFM maximum, and accepts 12 x 20 x 1” filters.

Whole-House Air Filtration System: The design is intended for use with inline duct fans, like the CLOUDLINE Series, to circulate fresh air by blocking particles like dust and dirt from entering your home. A hinge-sealed door provides easy access to the inner chamber while keeping the filter in place and preventing dust.

Applications: The air filter box uses standard MERV filter replacements that slide into the chamber’s filter slot. The included high-efficacy pleated air filter is capable of trapping particles ranging from 0.3-1.0 microns, such as dust, dirt, lint, and odor. The duct flanges are compatible with 4” inline fans, facilitating efficient installation for HVAC and grow applications. Using this in the starting end of your ductwork will dramatically reduce airborne particles in your home. Use with a high static pressure fan, like the CLOUDLINE Series of duct fans, is highly recommended for maximum filtration.
