Aeroseal offers a new and simpler design making it easier to use and more rugged than ever before for increased uptime. Aeroseal’s HSC 4.0 includes several updates improving its ability to apply certified, industry-standard methods to virtually eliminate duct leakage in any HVAC system, guaranteed. The latest iteration of our award-winning duct sealing technology not only makes it easier to use, more efficient, and more cost-effective, but it delivers greater value to our network of contractors who are working to reduce global CO₂ emissions.

New Features Keep Contractors in the Field, Sealing Ducts

Several new HSC 4.0 hardware features are designed to make the device easier to use, ensuring contractors can focus on sealing ductwork. 

• Quad Digital Power Control: Finer control of HSC 4.0’s pump and heaters ensure tighter seals and prevent overheating.
• Field Replaceable Antenna Extension: If a device’s antenna mount is damaged, technicians have a way to repair this connectivity issue in the field.
• More Robust Design: Enhancements including a stainless-steel solenoid diaphragm and new relay board contribute to more uptime and promote device longevity.

Proven Technology, An Industry Standard in Duct Sealing

Aeroseal is the trusted choice by HVAC contractors, duct cleaners, and solar installers to eliminate leaky ductwork. This proven technology dynamically measures the pressure and airflow inside the ducts with the use of a calibrated fan and user-friendly software.

The HSC 4.0 system then injects a fog of non-toxic sealant particles into pressurized ductwork to safely seal air leaks as big as 5/8” and as small as a human hair from the inside. The water-based sealant particles only accumulate where leaks are located, gradually closing them, ensuring leaks are sealed. The entire process is managed through HSC 4.0’s system software which measures and records airflow and leakage in real-time. Once the ductwork reaches its target goal, a post seal test confirms the amount of leak reduction, issuing a certificate of completion with before and after stats, equating to as much as a 90% reduction in duct leakage or more. 

Small Leaks, Big Problems

Buildings represent the fourth largest source of CO₂ emissions -- due in part to small leaks in an HVAC system’s ductwork. In fact, ASHRAE estimates 75% of homes and buildings contain leaky ductwork, making it clear that ductwork is inadequately sealed by manual solutions.Visit https://aeroseal.com/ for more.
