Grilles, Registers & Diffusers

TRUaire differentiates itself from competitors by meticulously manufacturing each component, painting them individually prior to assembling their grilles, registers and diffusers. Also known as the SmoothGlide technology, this process ensures that each product has 100% powder coat coverage and is highly resistant to corrosion and rattling. In contrast, many other registers on the market are painted after assembly, leading to flaking and corrosion when exposed to humidity.

TRUaire has created a full line of styles & models driven by distributor & contractor feedback
