A self contained HEPA Fan Filter Unit provides Class 100 HEPA filtered air in a horizontal laminar flow pattern within the workspace.
Standard voltage is 115 volts with other voltage options available. Separate On/Off switches for the fan and lights are located above the workspace. All 115 volt models are equipped with a 8 foot power cord and 3 – prong plug. Other voltages require electrical connection to the power source by a qualified electrician.
HEPA filters are 99.99% efficient @ 0.3 micron or larger with anodized aluminum frame. ULPA grade filters are 99.9995% efficient @ 0.12 micron, and are available as an option.
A pleated type, disposable prefilter rated at 30% ASHRAE efficiency is standard.
A solid state variable speed control is mounted on the M Series unit.
Horizontal flow clean benches have a polystyrene grille inserted in an anodized aluminum frame which is hinged to open. This permits removal of the HEPA filter without removing the HEPA fan unit from the frame.
All horizontal flow models with lights are equipped with a 4-lamp light fixture, 120 volt, 60 hz with T8, 32W electronic ballast. Fluorescent light tubes are not furnished with the units because of potential breakage during shipment.
