Krueger HVAC Air Distribution Products and Terminal Units
Krueger HVAC provides air distribution products and HVAC system components used in commercial HVAC applications, including diffusers, grilles, dampers, terminal units, and related accessories. The product portfolio supports applications such as air distribution, air balancing, variable air volume (VAV) systems, return air systems, exhaust systems, and flexible duct connections. For organizations managing complex commercial and industrial buildings, LONG Building Technologies supports the application, engineering, integration, and long-term support of HVAC systems that incorporate products from manufacturers such as Krueger HVAC.
HVAC Diffusers, Grilles, Dampers, and Terminal Units for Commercial Air Distribution
Krueger HVAC's product offering includes several categories of air distribution equipment and accessories designed for a variety of HVAC system requirements.
The diffuser lineup includes louvered face diffusers (SHR series), architectural plaque diffusers (PLQ series), perforated face diffusers (6600 series), and perforated return panels (6790 series). These products support supply air delivery, room air mixing, architectural ceiling designs, and return air applications.
Grille products include S80 return grilles, EGC5 egg-crate return grilles, and 880 double deflection supply grilles. These products are used for return air and supply air distribution in commercial applications, with certain S80 models also applicable in residential settings.
Krueger HVAC also offers airflow control products such as OBD opposed blade dampers and PRN100 radial fan dampers for air balancing and flexible duct installations. The LMHS single duct terminal unit supports HVAC systems that require compatibility with various control strategies and pressure classifications.
Additional accessories include hard ceiling frames, plaster frames, filter frames, straightening grids, insect screens, debris screens, square-to-round adapters, and other support components used with air distribution equipment.

Common Use Cases for Krueger HVAC Products
Krueger HVAC products are used in a range of air distribution and airflow management scenarios.
The SHR louvered face diffuser is designed for VAV systems experiencing above-normal temperature differentials, areas with higher load demands, applications requiring increased room air mixing, centrally mounted installations, and environments that require horizontal air distribution.
PLQ plaque diffusers are used where a clean ceiling appearance is desired, where radial air distribution is needed, and where access to ducts or dampers through a removable faceplate is beneficial.
S80 return grilles support return air distribution in both commercial and residential applications.
EGC5 egg-crate return grilles are suited for applications requiring large return air volumes, limited visibility through the grille opening, and designs that prioritize lower pressure drop and reduced sound characteristics.
880 double deflection supply grilles are used where airflow direction must be adjusted horizontally or vertically after installation.
OBD opposed blade dampers are installed directly behind grilles and registers for air balancing purposes, while PRN100 radial fan dampers are used in flexible duct and neck-mounted applications requiring airflow adjustment.
The LMHS single duct terminal unit supports low-, medium-, and high-pressure HVAC systems, applications requiring auxiliary heat, and projects utilizing pneumatic, analog, electronic, or direct digital controls.
The 6790 perforated return panel is intended for non-ducted return systems, exhaust systems, and lay-in ceiling applications.
Why Work With LONG
LONG Building Technologies supports commercial and industrial facilities through engineering support, HVAC system integration, and long-term lifecycle service. When projects involve air distribution products, terminal units, dampers, and related HVAC system components, LONG's role is to help apply and support these solutions within broader building systems.
Rather than functioning solely as a product supplier, LONG works as a technical partner that helps building owners, operators, engineers, and facility teams integrate HVAC equipment into complex building environments. Support may include product application guidance, system coordination, and ongoing service throughout the life of the HVAC system.
