Ac Slot Grill
Model LSDLSD
Polyaire Linear Slot Diffusers are an attractive alternative to the ceiling or high sidewall supply diffusers. Slot diffusers can be installed individually in set lengths or in a continuous line. They can also be installed in any type of ceiling application.
The modules are available with a 20mm or 25mm Slot with the number of slots ranging from 1 to 8 slots and are further available as fixed or removable core. (Fixed Core - Model LSD-FC, Removable Core – LSD-RC.
The air pattern control is adjustable from the diffuser face and is achieved by means of an adjustable pattern control with each slot, enabling a full 180º air pattern adjustment. The suggested volume control should be from the main duct run take-off, or from a butterfly damper fitted to the inlet of the cushion head box.
Construction is from extruded aluminium and the recommended maximum length for each section is 3 metres. Standard finish is powder coat white while other finishes are available to suit the interior and architectural design requirements.
- Nailor 5000 Series Linear Slot Diffusers provide architectural excellence and outstanding performance flexibility. An extruded aluminum border and frame construction ensures the dimensional precision of the diffuser and a precisely shaped aerodynamic pattern controller provides a full range of air pattern adjustment from vertical to a tight ceiling-hugging horizontal air pattern.
- 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.
Registers and grilles are essential in regulating and directing the airflow to and from the HVAC unit in your home, keeping your living space comfortable while also concealing the duct work. Lowe’s carries a variety of grilles, registers and air deflectors to ensure you get airflow where you need it most.
