The Laminar Flow Diffuser for critical environments has been designed to comply with ASHRAE 170, offering important safeguards for surgical patients. Used as the primary diffusers in operating rooms, the vertical piston of air created by the TLFR is used to discharge clean air over the patient during operations. Including snap-in, auto-centering filter retainers, the TLFR reduces the amount of time and effort during installation and removal of filters. This decreases the time a lab or operating suite is out of commission, allowing facilities to maximize profitability and patient care. The TLFR diffusers are available in aluminum and stainless steel construction with filter retainers that require no tools for installation or removal and automatically align the filter gel seal on the diffuser knife edge, opposed to filter retainers that need to be loosened and removed. In addition to its high-quality construction and ease of use, the TLFR assists in delivering lower energy consumption and aids in meeting lower first costs, stated the manufacturer.
