The ProSelect PSRG3W1818 is engineered for residential forced-air comfort applications, providing an excellent intake option for central return duct systems. This model utilizes a 1-way blade configuration paired with high-density 1/3-inch fin spacing, which provides enhanced concealment of the internal ductwork and filter media without restricting return air velocity.
Formed from high-grade steel, the square grille panel retains its shape and structural integrity over years of continuous system cycles. The resilient white powder finish resists chipping and scratching, providing a lasting, low-maintenance surface that aligns nicely with traditional and modern residential paint schemes.
When executing a residential system overhaul or replacing aged vent faces, matching the 18 in. x 18 in. nominal dimensions to the existing duct box is necessary for a leak-free fit. HVAC professionals and landlords select this fine-fin grille to optimize room air return while keeping internal system components discreetly out of sight.
