What is the Dentist Lab Laminar Air Flow Unit ?
There is a requirement for a clean air device to be located in dentists' surgeries to ensure that instruments that are autoclaved in do not become contaminated.
The Laminar Air Flow unit does this by taking air from an adjacent room using a fan, then passing it through a HEPA filter to clean it before discharging it into the surgery. The fan/filter module is designed to fit through a square aperture (500 x 500 mm) in an internal wall, and be connected to a mains socket. Instrumentation is kept simple to a mains power indicator, fan run/fan fail LED's and a three position speed selector.
Applications
The fan/filter module has been specifically designed for Dentists surgeries but would provide clean air protection in any room or lab application.
How does it work?
The fan/filter module is essentially a square metal enclosure with a HEPA filter at one end, and an inlet pre-filter at the other. Between the filters is located a backwards curved vane impellor or fan, and a control circuit. Beneath the HEPA filter is a small control panel.
The module works by taking air from an adjacent room, then passing it through the HEPA filter to clean it before discharging it into the surgery. The fan motor has 3 selectable speeds so that speed may be increased as the filter soils with time. A low fan or air flow alarm red LED is also situated on the control panel.
Advantages
The fan/filter module is a low cost unit which is simple to fit. It requires very little maintenance and its high fan efficiency means it is inexpensive to run. It may be left running 24 hours a day to ensure the surgery is kept extremely clean and free of airborne particles.
