MSR Steel, Fixed Pattern, Round Neck

Square/ Round Diffusers

These louvered diffusers come in a multitude of air patterns, sizes, and mounting methods—a wide range of products to choose from. A heavy-duty margin and one-piece removable center core make the MSR round neck diffusers the ideal choice.

  • Optional damper can be operated from the diffuser face by detaching the spring-loaded inner core assembly
  • To create a ceiling pattern at reduced air flows, the individual louvers are furnished with a horizontal lip
  • The snap-in core is held in place by two tabs which slide into the outer margin and works best where no screws are required

    Product Application

    Model MSR combines flexibility with versatility to meet your air distribution requirements. It is designed to provide a fixed horizontal discharge pattern and longer throws, making it suitable for high-ceiling applications. The horizontal lip featured on the deflecting louvers creates a tight ceiling air pattern and increases the discharge velocity. The high induction created by the diffuser then leads to excellent mixing. The flush appearance of the diffuser helps it blend in with the surrounding easily without being obtrusive.
    Product Application

    Features

    • Model MSR is of steel construction and features a round neck
    • Accessories include round butterfly damper (RBN,RBD), round opposed blade damper (RON,ROD), round radial blade damper (RRN,RRD), steel plaster frame (SMF) and aluminum plaster frame (ASMF)
    • It features a removable core. 1, 2, 3, or 4-way deflection patterns are available
    • The manufacturer provides published performance data tested in accordance with ANSI/ASHRAE Standard 70-1991
    • Standard finish is White (WH) electrocoat in an anodic acrylic paint, baked at 315°F for 30 minutes with a pencil hardness of HB to H
    • The trim frames and dampers are ordered separately and shipped loose for field installation
    • A round inlet will be provided as a factory mounted square to round transition

    Benefits

    Quiet Operation
    Quiet Operation

    The diffuser is capable of handling large volumes of air while maintaining low pressure drop and noise level.

    Improved Air Mixing
    Improved Air Mixing

    High induction produced near the face of the diffuser creates a tight ceiling air pattern for excellent mixing.

    Easy Installation
    Easy Installation

    The inner core assembly can be removed in the field without tools, making duct access and installation easier.
