Aldes Airlet 100 Rectangular Fresh Air Inlet - 5-3/4" TO 8" Sleeve
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 100 is of a rectangular design. The horizontal lines thus presented by the interior and exterior grilles make it unobtrusive in most decors.
AIRLET 100's may be installed either before or after the interior and exterior surfaces have been applied. Two telescoping sleeve combinations are available ( 5-3/4" to 8" and 8" to 12") to accommodate different wall thicknesses. A rough opening of 1-3/4" x 11" is required. Exterior and interior grilles are made of white plastic.
The interior grille, which incorporates a flow regulating damper, deflects a thin ribbon of fresh air upwards. In this manner, the AIRLET 100 provides draft-free fresh air which quickly mixes with the warmer air near the ceiling. A filter is provided in the sleeve and may be easily accessed for cleaning by removing screws on the interior grille. There are no manual controls.
