Criti-Clean Fan Filter Unit

Criti-Clean is a fan powered laminar flow HEPA/ULPA filter diffuser with a successful track record in a wide range of critical environments. Combining proven vertical air mass laminar flow technology with the latest ECM fan motor capabilities. The Criti-Clean FFU produces a non-aspirating, low velocity, uniformly distributed downward moving “piston” of filtered air. The AJ Mfg. FFU has a higher CFM output than competitive models, providing constant air volume of 250-700 CFM over a wide range of static pressures. It comes with a room-side accessible HEPA or ULPA filter and pre-filter. HEPA / ULPA filters have a separatorless 2" (51mm) deep media, integral test port and anodized aluminum gel seal frame.

The standard Criti-Clean FFU includes a computer controlled, variable speed ECM motor with internal microcomputer that provides low energy consumption, high performance and long motor life. The motor compensates for changes in static pressure, filter loading and more, greatly reducing the need for future balancing. A wide range of customizable controls is available with the ability to map and simultaneously control up to 800 linked units.

Type 304 stainless steel construction with all welded plenum is standard, built to meet the latest pressure testing standards and meets the Institute of Environmental Sciences and Technology (IEST) recommended practices for clean room air velocities.

A room-side digital CFM display and control offers instant visual verification, and can be set or adjusted in seconds.

The units can be provided with built-in white or green surgical grade LED lights.

AJ manufactures the FFU in their new 70,000-square-foot manufacturing facility and headquarters building in suburban Kansas City. This new space includes a second tower loader for another high-production laser cutters – an Amada Fiber Optic Laser with the world’s fastest linear speed (four times faster than conventional CO2 models). Adding another tower loader for auto-loading means that this laser will now be able to run around the clock, substantially increasing our capacity. Also installed is a new wash station, as well as a new state-of-the-art powder coating system, which will also allow for more throughput and give customers more finish options, all the while maintaining our industry-leading levels of quality!
