CF Bathroom Exhaust Fans are available as complete fan assemblies and come in easy-to-install contractor packages. The units are designed to fit 3- and 4-inch duct sizes and include a built-in damper that prevents backdraft, keeping tempered air in the home when the fan is not operating.
These thinline stationary louvers can be used for interior and exterior applications where a high, free area for improved airflow is required or when narrow frame depth and horizontal sightlines are desired.
Where do contractors even begin when they are deciphering the options available to them in the high-efficiency arena? Are there certain types of products that are essential? Or, is each situation truly unique? To try and tackle these questions head-on, members of The NEWS’ advisory board were presented with a simple prompt: If you were to design a high-efficiency movement/ventilation equipment system, what products would you choose for the job and why?
OEMs are striving to improve efficiencies at all costs and seeking ways to offer better options and improved solutions to consumers. However, in the blower marketplace, tightening global regulations are forcing manufacturers to create products that cater to highly-specific consumer needs based upon different requirements in different regions.
Manufacturers of all sizes are introducing energy recovery ventilators (ERVs); heat recovery ventilators (HRVs); blowers; air curtains; high-velocity systems; and high-volume, low-speed (HVLS) fans that push the industry forward in response to a demand for more efficient ventilation systems.
Being accountable for proper airflow delivery causes a tech to examine every portion of an installation differently. Airflow is no longer assumed since test instruments now measure it. Let’s look at some of the most common obstacles to achieving a successful air balance on a residential HVAC system.
Greenheck’s Vektor line of laboratory exhaust systems now offers a direct-drive arrangement with four-options available on Vektor-MH (High Plume), Vektor-MD (High Plume with Dilution), and Vektor-MS (Variable Geometry Nozzle) models.
The Backward Curved Centrifugal Fan, equipped with a plastic impeller, is high-voltage powered by a built-in electronically commutated motor (ECM), which enables the fan to run efficiently with low-energy transmission loss.
The Model ABD-SEA-E provides precise and automatic airflow regulation for supply or exhaust ventilation systems in any residential or commercial building. It is designed for use in any HVAC application with a static pressure between 0.2 and 2.0 inches water column.
Understand why system and duct design, duct tightness both inside and outside the envelope, and testing are the future of all successful HVAC companies. Get your head around the simple, practical steps to prove your company is scientifically superior to the competition, and ready for 21st century demands of smarter, more informed customers.
During this webinar, our expert speaker will discuss how contractors will be able to recognize the differences between blow through (HTHV) and draw through (MAU) technologies, as well as their respective strengths/weaknesses for different applications.
