The CE linear slot diffuser is designed to give continuous air diffusion with a pleasing aesthetic appearance. Hairline butt joints held by special alignment strips ensure that continuous, unbroken runs of active and dummy sections are readily achieved. The SDS linear slot diffuser is designed to satisfy architectural applications that require continuous lengths without compromising air distribution performance. These linear slot diffusers feature fully adjustable, aerodynamic pattern controllers fabricated from extruded aluminum, and are available in a large selection of frame styles.

A Vairtech slot diffuser is a building component used to deliver air to a room. These diffusers serve as a critical component in a heating, ventilation, and air conditioning (HVAC) system. Unlike traditional square or round diffusers, a slot diffuser features a long, narrow design. This special shape makes it easy for builders to fit these diffusers into tight spaces, and helps to conceal the diffuser from view to create a more aesthetically pleasing design. A slot diffuser may also be known as a linear or linear slot diffuser in some areas.

1. Plenum Slot Diffusers BA Series is made to install in parallel t-bars that form a continuous slot. BS Series is made for a standard t-bar lay-in application. Constructed of 24 gauge steel with exposed surfaces and pattern controller painted black.
2. CONTINUOUS SLOT DIFFUSER introductionThe LCS series diffuser has been developed to provide a simple and economical form of continuous slot air distribution system and is suitable for variable air volume schemes or fan coil applications.

Central heating and cooling systems distribute air through a building using a series of metal ducts. A slot diffuser sits at the duct terminal in each room and allows heated or cooled air to enter the space. Each slot diffuser features a linear plenum, or box that fits above the ceiling. This plenum space helps to improve air flow, and allows air to enter the space at an even, steady pace. The surface of the slot diffuser typically features a set of adjustable fins to further control and direct the flow of air.

Contractors may utilize a number of slot diffuser installation methods. They are typically concealed within a suspended ceiling, but may also be placed in dry wall partitions or ceilings. Some designs call for these diffusers to be installed in soffits above a window, or in a built-out area below a window sill. In some applications, the diffuser may even be placed in the floor. In rare cases, linear slot diffusers may also take the place of an exhaust grill to return air from a room back to the heater or air conditioner.

Continuous Slot Diffuser

Slot diffuser units offer a number of advantages over traditional square or round diffusers. They are an unobtrusive way to supply air to the room, and are designed to blend in with surrounding finishes. Slot diffusers also provide a high level of control over the design and layout of a space, and allow users to utilize fewer diffusers while supplying the same volume of air flow.

Compared to other types of diffuser models, slot diffusers generally represent the most expensive method of air distribution. An HVAC system equipped with linearslot diffusers will cost more in terms of upfront material costs than one equipped with round or square diffusers for the same volume of air. The linear plenum design also generates more noise and allows for greater pressure drops than more traditional diffuser designs.
