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.
