Tamarack Technologies, Inc., headquartered on Cape Cod Massachusetts was founded in 1993. Tamarack is an industry leader in ventilation solutions, manufacturing state-of-the-art whole house fans, indoor air exchange products and electronic controls using minimal or no energy. Our products save money, are maintenance free and reduce the carbon footprint while delivering a cleaner, comfy, healthier home environment. 


Our products reduce energy expense and improve indoor air quality (IAQ).

Whole House Fans:
Air exchange is critical for a healthy, comfortable home. Our products get the job done efficiently and economically. The HV® and Ghost® whole house fans bring cool outside air into the home and push it out through the attic. The TC series is designed for sunrooms and solid roof/wall applications. The Mainstream® is a replacement fan for manufactured housing. The Dragon® series will remove dangerous fumes and toxins from the garage. The Multi Aire IIP will deliver 400 cfm of filted air through four ports for in homes requiring make up air caused by high volume exhaust. The Infinity® ducted whole house ventilation system offers an infinite range of positive and negative air flow solutions for multiple applications. 

Fan Controls: 
The Airetrak©1A Advantage is an electronic control that allows the programming of the bath fan to operate intermittently throughout the day. This helps reduce the propensity of mold build up in bathrooms and improves indoor air quality. The Airetrak 62.2© fan control converts the existing bath fan switch from on and off... to hi and low speed. This meets/exceeds Energy Star, LEEDS and ASRAE 62.2 standards for indoor air quality.

Backdraft Dampers:

The Cape Backdraft Damper fits inside 4", 5", 6" 7" or 8" ducting. It requires minimal pressure to open and close. This allows full flow of fan and SERIOUSLY outperforms a traditional butterfly damper. Air flow is in one direction, designed for cold and hot streams. Tested to NFPA 255 and UL723 standards.

Pressure Balancing:
The Return Air Pathway (R.A.P.) allows the movement of air from one room to the next, equalizing pressure in the home while dampening sound and light from one room to the next and is easily installed in a retro-fit application for walls. The Perfect Balance In-Door pressure relief grille is designed to balance pressure within the home and installed as a simple retro-fit to the bottom of interior doors.

Air Purification:
The DreamAire 5000 is a compact portable HRV that has a single exhaust duct. It features an Electrostatic Precipitation Filter (ESP) that kills 97% of viruses, molds spores and bacteria before entering the home. Features a "lung" action reversing direction of air flow every 30 seconds, in and out of the house on a 4, 8, 12 or 24 hour cycle.

The Multi-Aire IIP brings outside air in through a single 8" duct, filters it through a merv 13 filter. Four-4" ductable ports allow delivery of fresh clean air to multiple areas.
