We have added videos on how to assemble our CFB and unboxing our Balanced Make-up Air System components. It is part of our ongoing goal to share new and interesting content and information to help you with your next project. What is a CFB? What is a Balanced Residential Make-up System? Lets break them down for you.

CFB Series MERV-13 Inline Filter Boxes

A CFB filter box is a high-performance solution for any application requiring in-line filtration. Constructed from 5052 H32 aluminum, the CFBs holds a standard 4″ filter and are designed to fit either 6″, 8″, 10″ or 12″ diameter duct. The lid attaches securely with latches, and opens easily for quick filter replacements. MERV-13 filters are included with every unit, but you can also upgrade to a MERV-15 filter. The higher the MERV rating the better the filtration and the cleaner the air will be in your home.

A balanced make-up air system is designed to “make up” the air in your interior space that has been removed due to process exhaust fans. This type of HVAC solution pulls in fresh, tempered air from outside your building to replace existing air that cannot be recirculated. The International Residential Code (IRC) requires that makeup air be provided for kitchen hood exhaust systems with a capacity of 400 cfm or greater. Our balanced make-up air system can be customized to fit your needs with silencers, electric heater for cold climates and wall/roof caps.

Both provide better air filtration for your home to keep the air clean of allergens, smoke odors and particulates in the air, as well as provide the in-home air circulation that you need. You can check out our videos by clicking the links below.

Smoke And Grease Be Gone…

The Kitchen…a place of interest for those of us who like to eat.

Most of us are familiar with the noisy, rattling, ineffective range vents usually installed in a home. These units typically have some form of fan and motor right above the range, causing all sorts of racket, and struggle to pull all the smoke from the fish that my wife I burned last night.

Is there a better way? You bet. Fantech Component Kitchen Exhaust systems. These have the a powerful fan located in the attic, coupled with a Silencer (muffler for the automotively inclined) that is able to pull massive amounts of air and do it without driving you from the kitchen with noise.

The ideal setup would have some sort of Hood Liner, a Backdraft Damper to prevent air from coming down the pipe when the Fan is off, the Silencer, The Fan and some sort of discharge hood in that order. All that is left is some hard wall galvanized pipe and you have a vent system that is unparalleled in terms of performance and quiet operation.

Sizing the system can be done by using our handy System Builder or a few simple rules of thumb:

  • The hood should be wider than the range.
  • Multiply the size of the hood to get surface area (36×22=792sq in)
  • Divide that by 144 to get square footage (792 sq in=5.5 sq ft)
  • Use around 75-100 CFM per square foot minimum to get the size fan you need
