Now AJ Can Provide Everything You Need for Hospital Operating Rooms

Over the last year, we’ve told you how AJ Manufacturing is helping our customers use valuable ceiling space more efficiently. Our Criti-Clean Fan Powered Laminar Flow HEPA Filter Diffusers with built-in surgical grade lighting (both fluorescent and LED) do the work of two operating room fixtures in one unit. Even better, options for our Laminar Flow Diffusers like 100% shut off dampers and room-side access to filters and pre-filters also substantially increase efficiency when it comes to maintaining these units.

Now we’re proud to offer you an even more convenient, time-saving solution that can mean greater efficiencies for hospital operating rooms: our new heavy-duty Ceiling Grid Systems. That means AJ – the company you know and trust for custom and standard stainless steel air distribution products – can now also be your one-stop source for complete ceiling systems for hospital critical environments.
