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.

Grilles and Registers. We sell both stock size as well as custom made rectangular grilles and registers as well as stock round registers for both supply and exhaust applications. Made to order grilles and registers: All of our Dayus grilles are cut to size, aluminum construction, rustproof and only 40% weight versus steel.

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.

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.

Many heating, ventilation and air conditioning (HVAC) systems are made up of traditional duct work that runs between the furnace and the individual rooms of a house.

Heat registers are vent covers that cover the hole in the wall or floor where the duct enters the room. Louvres, or dampers, are often attached to the back of a heat register. These adjustable louvers/dampers can open or close the register to open and close the flow of air. Many of our grilles have an added custom damper or louver option and all registers include a damper.

A supply vent cover comes with a louver/damper to control air flow. These are only used for vents that supply air and are optional.

A grille is a vent cover through which air is blown into or out of a room for circulation back to the central heating or cooling unit. These are commonly found if you have heating or central air conditioning. A grille has no damper to control air flow, so air is left to flow freely. Grilles do not have the damper normally found on registers.

An air return is a vent grille that is usually located either in a hallway or in the ceiling, and its purpose is to extract air from a room and recycle it through the system to further condition it by cooling or heating. Air returns don't have a damper as they need to allow free flow of air into the vent.
