1 SLO DIFFUSERS ALS SERIES SLO DIFFUSER For, and Installation Series ALS Architectural Linear Slot Diffusers are designed for installation in the ceiling, sidewall or sill and are recommended for supplying heated, ventilated or cooled air and for returning or exhausting room air. Air pattern directional changes through are effected by the integral "Uniflex" combination pattern and volume controller, permitting pattern adjustment to meet changing requirements. heir reliable performance assures confident use of cooling temperature differentials up to F at predicted low air motion FPM in the zone of occupancy. Series ALS Diffusers perform efficiently with air loadings of to CFM per square feet of floor area or to air changes per hour (based on ft. ceiling height) at a sound level range of to. When installed in the ceiling, Series ALS Diffusers provide a horizontal air path that is adjustable through in each slot opening. One to ten slot ALS Diffusers can be adjusted to provide oneway or twoway air patterns by directing the controller as required to either side. Vertical downward air pattern can be adjusted from all slots. A combination horizontal pattern and vertical down pattern can be effected from a two (or more) slot diffuser. Series ALS diffusers are fabricated of highquality aluminum extrusions. he pattern controller is coated dull black to accent the slot opening. Components are mechanically interlocked together for a blemishfree appearance. Keyways and splice plates facilitate sections over to form continuous lengths. Ninety degree mitered corner sections are furnished in one piece. ALS FEAURES HREE SLO SIZES, /", /" and ". ONE O EIGH slots wide for air volume of 0 CFM per foot.

"UNIFLEX" ADJUSABLE PAERN AND VOLUME CONROLLER provides positive positioning, constant static pressure, constant outlet area. Concealed mounting brackets fit in a hemmed duct collar to positively hold the diffuser in ceiling and sidewall installations. Series ALS diffusers used for return or exhaust air are identical to supply sections except the pattern controller is removed to increase air capacity.
