Improving Air Quality and Comfort with Destratification Fans for Restaurants & Bars
Restaurants and bars must balance two very different indoor environments. Kitchens generate substantial heat, moisture, odors, and airborne cooking contaminants, while dining rooms and bar areas need to remain comfortable and inviting regardless of how busy the establishment becomes.
Changing occupancy, kitchen exhaust, frequently opened doors, lighting, cooking equipment, and high or exposed ceilings can all affect temperature and airflow. Airius systems can help improve circulation, temperature consistency, and indoor air quality while working alongside the restaurant’s required HVAC and kitchen ventilation systems.
The Challenge
Restaurant HVAC is particularly complex because the kitchen, dining room, and bar cannot simply be treated as one environment. Commercial kitchens require significant exhaust to remove heat, moisture, grease, and cooking effluent. ASHRAE recommends maintaining kitchens at a slightly negative pressure relative to adjacent dining areas to help contain cooking odors, while dining spaces should have even air distribution without noticeable drafts or significant temperature variations.
That creates a balancing challenge. Exhaust systems continuously remove large volumes of air, outdoor and replacement air must be introduced, cooking equipment generates substantial heat, and customer occupancy can change dramatically throughout the day. Dining areas can experience their own problems including hot and cold spots, stagnant air, lingering odors, and temperature stratification in spaces with high ceilings. Without effective circulation, conditioned air may not be distributed where customers and employees actually experience it.
The Airius Solution
Airius fans can provide supplemental air circulation and air treatment within appropriate restaurant and bar spaces while complementing required kitchen exhaust, makeup-air, and HVAC systems.
For restaurants and bars, two Airius systems are particularly well suited.
PureAir Series
The PureAir Series is particularly valuable where indoor air quality and odor control are priorities. PureAir combines Airius air circulation with NPBI™ Needlepoint Bipolar Ionization technology. The system continuously distributes treated air throughout the occupied space while helping address airborne particles and odors, including cooking-related odors and VOCs. This makes PureAir especially appropriate for dining rooms, bars, breweries, entertainment areas, and other occupied spaces where odors and stagnant air can affect the customer experience.
Retail EC Series
The Retail Series EC provides a strong solution for restaurants, bars, dining rooms, and hospitality spaces where temperature balance and targeted circulation are the primary concerns. Its compact design and variable-speed EC operation allow airflow to be matched to different seating areas and room configurations without introducing excessive drafts. Airius specifically identifies restaurants among the recommended applications for the Retail Series. BACnet and 0–10V integration also allow circulation to operate alongside existing building controls and adjust as occupancy and indoor conditions change.
Potential Benefits
A properly designed Airius installation could help reduce hot and cold spots, improve air circulation throughout dining and bar areas, mitigate persistent odors, reduce stagnant air, and help existing HVAC systems distribute conditioned air more effectively. PureAir systems can add supplemental air treatment where indoor air quality is a priority, while destratification can help facilities recover conditioned air that would otherwise accumulate near high ceilings. These systems supplement rather than replace required kitchen exhaust, makeup-air, ventilation, and pressure-control systems.
Proven Results
Bierstadt Lagerhaus in Denver selected the Airius PureAir Series to address indoor air quality within its restaurant and brewery environment. Airius identifies the installation as a restaurant application demonstrating how PureAir can combine continuous circulation with supplemental air purification in a busy hospitality setting.
The application is particularly relevant to restaurants and bars because PureAir addresses two challenges simultaneously. The fan continuously circulates air throughout the occupied space while NPBI™ technology is designed to help reduce airborne particles and neutralize odors, including odors associated with cooking.
better airflow is on the menu
Every restaurant and bar has different kitchen equipment, exhaust requirements, seating layouts, ceiling heights, occupancy patterns, and HVAC systems. Airius systems can be selected and positioned around those conditions, using PureAir where indoor air quality and odor mitigation are priorities and Retail Series fans where targeted comfort and temperature balance are the primary goals.
The objective isn’t to interfere with the carefully balanced kitchen ventilation system. It’s to improve the air customers and employees experience throughout the rest of the space.
