Every door that swings open in a commercial kitchen presents an opportunity for something unwanted to slip in. It might be a cloud of hot, humid air or a curious fly. Either way, the result is the same: sanitation risks increase, food safety takes a hit, and the HVAC system works harder to keep the environment stable.

For operations managing constant foot traffic, open service windows, or climate-sensitive zones, traditional pest control methods often fall short. Chemical sprays have health concerns, and manual traps rely on visibility and timing. None of them stops the problem at the threshold.

What’s needed is a smarter way to protect the kitchen without closing it off; something automatic, unobtrusive, and built into the very entrance itself. That’s where air curtains come in.

What an Air Curtain Actually Does

Air curtains operate by creating a continuous stream of high-speed air across an open doorway. This invisible barrier helps seal off the interior from whatever is on the other side, whether that’s flying insects, exhaust fumes, or unfiltered outdoor air. Unlike a physical door, the air curtain allows complete visibility and access, letting staff and customers move freely while keeping the environment inside stable and protected across multiple entry points. Some are mounted above main entrances to reduce energy loss. Others are fitted to drive-thru windows or walk-in coolers to help isolate temperature zones. Regardless of placement, the goal is the same. Air curtains serve as a frontline defense for kitchens that cannot afford to compromise on cleanliness or comfort.

A Pest Control Solution That Works Without Chemicals

Mars Air Systems has built its reputation on providing commercial-grade air curtains that offer consistent, chemical-free pest protection for kitchens, restaurants, and institutions. With models designed for everything from service doors to display cases, Mars delivers targeted pest control that activates the moment a door opens, repelling flies, mosquitoes, and other airborne pests before they ever enter the space.

The system runs continuously and quietly, forming a seamless part of the building's structure. There are no sprays to reapply and no staff training required to maintain protection. For foodservice operators who want to remove the guesswork from pest control, Mars offers a proven, no-contact solution that works behind the scenes and around the clock.

The Safety Benefits of Keeping Flies Out

Kitchens are held to high sanitation standards, and for good reason. The presence of flies can lead to real health concerns. These insects can spread bacteria linked to cholera, typhoid, dysentery, and other foodborne illnesses.

Mars air curtains help reduce these risks by keeping disease carriers from ever getting through the door. By supporting clean entry points, they reinforce the daily efforts of kitchen teams and help protect both front- and back-of-house environments. For operations working under strict safety guidelines, this technology adds a practical layer of defense that enhances compliance and confidence.

How Air Curtains Support Energy Efficiency

Mars Air Systems designs its equipment to do more than stop pests. Their AMCA-certified models also help maintain temperature consistency throughout a facility. This makes it easier for HVAC systems to operate efficiently, reducing energy use and keeping indoor environments more comfortable.Whether installed at the loading dock, a walk-in entrance, or a customer-facing doorway, these air curtains help preserve the separation between outdoor and indoor climates. Over time, that separation translates into lower energy bills and less wear on climate control systems.

Cleaner Air With Added Protection

For operations that want even more control over what enters their kitchens, Mars offers a Clean Air Series. These advanced models include features like HEPA filtration, UVC germicidal lamps, and plasma ionization. Together, these enhancements help sanitize the air entering the space, reducing the presence of allergens, pathogens, and odors.

This level of purification is beneficial in hospitals, institutional kitchens, and any environment where indoor air quality directly affects food safety or public health. The Clean Air Series provides another way Mars helps facilities meet the highest standards of cleanliness at the point of entry.

Proven Results in Real-World Kitchens

Mars Air Systems has been installed in delis, food processors, restaurants, and hospitality venues across the country and is trusted in environments where food safety, guest experience, and operational efficiency matter.

For foodservice teams looking to repel flying insects, maintain climate control, and improve air quality, all without relying on chemicals, options from Mars provide a single, effective solution. Making it easy for operators to protect their staff, customers, and investments.
