Aldes Airlet TL98 Adjustable Fresh Air Inlet
Adjustable 4" round sleeve can be used in walls from 2-1/2" to 8" in thickness.
Make-up air is an essential element in a complete central exhaust indoor air quality ventilation system, particularly in structures that are well-insulated and build tightly. The introduction of fresh air from the exterior provides the make-up air to replace air being exhausted by an exhaust fan. Thus, indoor relative humidity levels are kept to acceptable levels and a healthy atmosphere is assured. Fresh air vents protect from excessive negative pressure in the living space and can also be a safeguard from the backdrafting of toxic combustion by-products.
Best results will be obtained in homes with tight air-vapor retarders, and continuous central exhaust from bathrooms, kitchen and laundry.
The goal is to achieve a home with slight negative pressure, to avoid exfiltration into the walls and attic. Install one fresh air inlet in each bedroom, and living/ dining room area(s)1. Inlets should not be installed in kitchens, bathrooms or laundry areas. These areas should be exhaust points to a central exhaust system. When placed high on exterior walls, drafts from the inlet should not be noticeable. The interior fixture produces a thin ribbon of fresh air deflected upwards, which quickly mixes with the warmer air near the ceiling.
The Airlet Model TL98 manually adjustable fresh air inlet incorporates a unique variable precision control damper that provides superior comfort control for the user. The damper is manually adjusted using a discreet slide control accessible from behind the front cover, which prevents unwanted tampering. An aesthetically pleasing interior grille is both attractive and multifunctional. The slightly arched grille face and horizontal lower slot take advantage of air currents to provide condensation protection. Superior air distribution pattern ensures draft-free performance. Every Airlet TL98 includes a permanent easily accessed washable filter, expandable wall sleeve, and exterior louver. The white color blends well with any decor and is cleaned simply with a damp cloth.
